INCLINATION MEASUREMENT - HYSTORY AND DEVELPMENT 

• The inclination measurement was used already in ancient times 

- for the construction of buildings 

- for the creation of simple city maps 

- for the navigation at sea. 

• The use of new materials and working methods allowed the development of new 

and more accurate inclination measuring instruments 

• 1727 the first Sextant was built according to Isaac Newtons designs 

• 1760 the first Theodolit was made by the physic Dollond 

Theodolit from 

W. & S. Jones 

Sextant 

Sir Isaac NEWTON 

1642 - 1727 

• Especially in the Quality Assurance the inclination measurement is 

applied in various different forms 

• An inclination measuring instrument is used for: 

- measuring an angle 

- measuring the flatness of a line, e.g. of a machine guide way 

- measuring a flatness surface profile 

- long term monitoring of objects 

• The „classic“ spirit level is, due to the higher requirements of precision, resolution and sampling time, reliability as 

well as data storage and protocoling more and more replaced by electronic inclination measuring instruments 

• The latest development clearly tends towards inclination measuring sensors bound in networks with the possibility 

of data transmission over short and long distances and collected in appropriate units such as computers and display 

units (Levelmeter)

Elektrolyte-Vials 

CLINOMETER 

Electrolyte vials are made of glass similar to 

precision vials but filled with a liquid that is 

electrically conducting. By inclining the vial 

the outer portions of the vial (electrodes) will 

be more o e or o less ess co covered e ed by the e liquid. qu d The e 

electrolyte vial will supply a voltage 

proportional to the inclination. 

CLINOMETER with built-in precision vial 

A clinometer has a precision vial 

combined with a precision mechanical 

device allowing a +/-180° scale 

positioning. 

The mechanical disk can be adjusted by 

using a micrometer until the precision vial 

shows an absolute horizontal value. 

On the large scale and on the 

micrometer scale the angle can be 

read to a precision of 0.3mm/m

Inductive systems 

Range II: +/- 0.150 mm/m 

Range I: +/- 0.750 mm/m 

Excellent zero point stability 

Measuring principle: 

The electronic inclination measuring instruments use a 

friction free suspended pendulum. At the end of the 

pendulum a ferrite core is fastened which is penetrating a 

double winded coil fed by alternating current (principle of 

an inductive probe). 

The output voltage is directly related to the instrument‘s 

inclination.

Capacitive measuring systems 

These electronic levels are based on the pendulum properties of a 

friction free supported disc of mass. A frequency is supplied to two 

ceramic and copperplated electrodes, which together with the 

pendulum p disc supported pp in the shielded and dust pproof ggap p 

between them, build a differential capacitor built of 2 ceramic and 

copper plated electrodes deliver the angular signal. This unit is

3. ANGULAR MEASUREMENT WITH LASER 

Laser 


Target laser 

The system consists of a laser sender and a laser 

receiver unit. The sender unit is high stabilility semi 

conductor laser prcisely adjustable with a 

mechanical device to the target. 

The receiver unit is a 10x10mm PSD (Position 

sensing detector), an opto electronic device with a 

complete amplifying and computing electronic 

based on a DSP (digital signal processor) 

Laser Interferometer 

The measuring system consists of a laser 

with detector, an angular interferometerreflector 

and a reflector. 

The laser beam is split in the 

interferometer and runs from there on in 

two different paths. (Measuring beam and 

reference beam) 

On the return way the two beams will be 

superimposed to one beam again. The 

difference in path distance leads to a 

difference in return time and therfore a 

phase difference is the result. 

This phase difference results in a 

interference that can be measured.

spirit p levels ( (up p to 50 µ µm/m) ) are 

manually precision scraped!!! 


Most important advantages of the 

new concept: 

1. Simple adjustment system 

2. Excellent view on the vial 

3. Modern design 

4. Tested according to 

DIN standards 

5. Stability of twist 

6. Comfortable handling 


WHAT IS „INCLINATION“? 

The definition ANGLE is the difference 

between two straight lines g1 and g2 in 

a flat plane. An angle will be created at 

the cross section between the two lines 

g1 and g2. 

The INCLINATION is a specific angle 

related to the angle a created between 

the line g3 and a horizontal line g4, 

whereas h th the hhorizontal i t lli line g44 li lies iin th the 

intersection between a vertical plane E2 

and the horizontal (reference) plane E1, 

which must be absolutely horizontal. 

Angle Inclination 

ANGLE α between lines g1 

and g2 g 

INCLINATION α between 

a line g3 and the „zero“ line g4, 

e.g. in [Deg/Min/Sec] or [Rad] 

g4: horizontal zero-line 

E1: horizontal plane 

E2: vertikal plane

MOST COMMON UNITS USED IN INCLINATION MEASUREMENT / 

DESCRIPTION OF AN ANGLE 

1 µm/m 

α 

Base length B = 1m 

Angle α, e.g. in xx°xx‘xx‘‘ or in mRad or 

Height „H“ refering to a base length „B“, e.g. mm/m or µm/m 

Multiply height „H“ and base length „B“ with factor 1000 


Result: 1µm/m = 1mm/km 

WHAT IS A POSITIVE, RESPECTIVELY A NEGATIVE INCLINATION? 

Positive negative 

A positive inclination is, when the line respectively the plane, 

in the measuring direction is inclined. The negative inclination is 

therefore when the line or plane is declined

Careful choice of coordinate system 

The program allows (under certain conditions) the 

integration of elements which have been measured 

earlier as well as the comparison between elements 

from separate measurements. 

This requires though the appropriate positioning 

within the coordinate system. The relevant entries 

are used to label the measuring results. Correct 

labeling allows the correct allocation for later 

analysis.

2D-AUTOMATIC REVERSAL MEASUREMENT HEAD ZEROMATIC 2/1 + 2/2 

Advanced technology in long-term measurement 

in X- and Y-axis 

The new developed high precision 2-axis inclination measurement 

instrument ZEROMATIC 

The ZEROMATIC is available in two different versions: 

• ZEROMATIC 2/1: 

Inclination measurement head with one ZEROTRONIC Sensor. 

Each single measurement is established by a reversal measurement, 

which delivers the absolute inclination value in both X- and Y-axis. For 

each measurement the ZERO OFFSET is calculated and compensated. 

Each measurement sequence, which consists of a complete reversal 

measurement, gives one set of output data. The user can define the 

interval between 2 sequences. 

• ZEROMATIC 2/2: 

Inclination measurement head with automatic reversal measurement with 

two ZEROTRONIC Sensors. The absolute inclination values in X- and 

Y- axis can be read continuously. At defined intervals, which can be 

set by the user, the zero offset is evaluated and compensated through a 

reversal measurement. The length of the interval is dependent on the 

required accuracy.

Longterm Monitoring of Dams, Bridges and Buildings with ZEROMATIC 2/1 + 2/2 

Our sensors ZEROTRONIC and 

ZEROMATIC are very well suited for long 

term monitoring of civil engineers 

constructions like dams, bridges or buildings. 

Very often such applications require data 

gathering and data transmission with remote 

indication and alarming. For such tasks we 

recommend the use of a DC3 system. 

DC3 allows the gathering of various types of 

sensors like GPS receivers, totalstations and 

inclination sensors. The data is then 

transmitted by internet, by phone lines or 

wireless to a central monitoring station. 

The picture left shows a typical display of a 

damn which is monitored with the help of a 

DC3 system.

EXPRESS REPARATUR SERVICE - WYLEX 

EXPTESS REPAIR SERVICE ERS / WYLEX 

A large number of customers are very dependent on their instruments as they are used daily. They can therefore not do 

without them for a long period of time. For these cases WYLER SWITZERLAND has created a new service called 

„Express Repair Service, ERS / WYLEX“. Employing this service the transport time from the user to WYLER 

SWITZERLAND and back and thus the complete repair time can be reduced considerably. 

A simplified description of this service: 

WYLEX 

• The customer announces the repair request to the local WYLER partner in his country 

• The WYLER partner will inform the customer about the possibility of the ERS / WYLEX service outlining the 

advantages and consequences of this service, such as e.g. 

o reduced total repair time 

o required acceptance to repair without quote up to 65 % of the price for a new instrument 

o suitable it bl packing ki for f air i transport t t 

o expenses of the ERS / WYLEX 

• In case the customer decides to use the ERS / WYLEX, the customer informs the local WYLER partner or 

directly WYLER SWITZERLAND providing the necessary data 

• The customer will receive all information and instructions necessary for a smooth handling, the customer has 

just to pack the product suitably and to fill in a form for the TNT courier service as well as to announce the 

readiness to the local TNT office for pick-up. Everything else will run automatically 

• Products reaching WYLER SWITZERLAND under this service will be handled with first priority, and the 

instrument will be returned using the same carrier 

• The invoicing will be through the WYLER partner in your country 


WARTUNGSVERTRAG FÜR WYLER-GERÄTE 

MAINTENANCE CONTRACT 

Measuring systems are becoming more and more complex and are therefore subject to continuous 

supervision in respect of quality and reliability. For this purpose WYLER SWITZERLAND offers the 

option of a MAINTENANCE CONTRACT with the purchase of new instruments. 

The MAINTENANCE CONTRACT offers the following services to the customer: 

Maintanance contract 

• Complete inspection and re-adjustment of the instrument / system in a yearly interval as 

well as remedy of defaults reported by the customer 

• The scope of delivery includes an internationally recognised Calibration Certificate SCS 

for the entire system confirming the performance after the service intervention. Traceable 

certificates SCS are issued according our accreditation as a calibration laboratory by the 

Swiss authorities 

• Highest priority for repair works 

• Technical enhancements and modifications published by WYLER if this is considered suitable 

82



New WYLER Service Concept 

VISION: Our customers should feel like this: 

“There are no problems with WYLER products, and in the rare 

case that there is a problem WYLER solves it efficiently 

and to my full satisfaction” 

We would like to make it as easy as possible for WYLER customers to deal with 

us us. We would like them to feel like WYLER being a “local local supplier” supplier . 

Wartungsvertrag 





Products under warranty: 

As of January 1, 2007 WYLER AG will absorb transportation costs to and from 

Switzerland for products showing errors during the warranty period There are 

very few WYLER instruments which fail during the warranty period. In order to 

increase customer satisfaction we would like to make sure that the customer 

who just invested into a new instrument does not have high costs if the 

instrument fails. WYLER is only absorbing the transportation cost and the 

cost to import the instrument into Switzerland. 

83





Products no longer under warranty 

IIn order d tto reduce d di distance t to t WLYER we would ld lik like to t make k sure that th t a 

Japanese customer does not pay more than a European customer and that a 

South American customer has the same short “distance” to WYLER (in terms 

of transportation costs) as a Turkish customer. 

Transportation costs (max amount for the whole world) 

• Clinotronic Plus: CHF 75.- for each way 

• Clino 2000: CHF 100.- for each way 

• Single Level 

(Minilevel / BlueLEVEL): CHF 125.- for each way 

• Engineers Set : CHF 150.- for each way 

• NivelSWISS: CHF 150.- for each way 

The difference between the above mentioned amount and the real 

transportation cost will be absorbed by WYLER for the transport to 

Switzerland.
