Description and examplesThe inductive analog sensor is suitable for noncontactingmeasuring of distance or positionreferred to metals. The measuring principle isbased on the physical effect of change of qualityof a resonant circuit which is due to eddy currentlosses in conductive material.The high-frequency pulsating field of a LCresonant circuit leaves at the active surface of thesensor and is periodically excited by a pulsestage. As soon as electrically conductive materialenters the field eddy currents result. Energy istaken from the resonant circuit, and its amplitudeand decay time are influenced proportionally tothe object distance. A µ-processor serves forintegration of the energy of the resonant circuitand determines the resulting output signal.The electro-magnetic field is non-interacting, i. e. itdoes not produce any heating in the object to bemeasured nor does it have magnetic influence.Acc. to function measuring is carried out referringto moved or stationary metals. For fast processes ithas to be considered that the periodically excitedresonant circuit reaches a measuring rate between100 and 250 per second.The robust design in potted housing and easyhandling make possible industrial standardsolutions as well as sophisticated applications.By means of two incorporated push-buttonsmeasuring range and individual curve shapescan be programmed. Apart from the measuringvalue output a serial interface is available.Distance measuring in case ofaxial approach of the object to be measuredDisplacement measuring in case ofradial deviation of the object to be measuredMeasuring of non-circularityor angle of rotationSelection in the production area:Height, surface or material propertiesProxitron GmbH • Gärtnerstraße 10 • D-25335 Elmshorn • Tel.: 04121 / 2621-0 • Fax: 04121 / 24404 • mail@proxitron.de

During this procedure the electro-magneticalternating field of a sensor induces eddy currents intothe surface the metallic object to be measured. Thetransmission of energy changes the vibrationbehaviour of the oscillator and is evaluated by theelectronic control unit. By means of a specialmodulation procedure the max. possible measuringrange is achieved. Sensors with measuring rangesbetween 0 to 5 and 0 to 150 mm are available.Practically accuracy’s between 1-2/10 mm can bereached because of inhomogeneity of the objectmaterial regarding alloy and hardness. If veryhomogenous material is used, accuracy’s upto 1/100mm are possible as well.The mobile measuring station MSZ 002 is suitable foroperation with 1 or 2 sensors. The internal battery iscapable of providing 12 hours operation.The movable measuring skid MAZ 002 fitted with 2sensors is moved through the strand guide of acontinuos casting plant. Each sensor detects thedistance to the rolls in passing. The MSZ computerdetermines and stores the min. gaps between the rolls.The internal display always shows the last three gapvalues. It is possible to store up to 2048 gaps in theintegrated Flash-ROM (permanent) and to read them atany time. Communication with the PC is effected via aRS232 interface.Thanks to the menu-guided operation the roll gapsensor can be applied comfortably and adjusted to theapplication in question. The MSZ 002 can beconfigured to operate in German, English and Spanish.The measuring skid MAZ 002 consists of two sensorsarranged axially in opposite measuring direction. The Ato D converter continuously produces the measuringvalues for both sensors which are transmitted to themobile measuring station via a RS485 interface and aconnection cable.Measuring accuracy and linearity are influenced byshape and material of the measuring objects. Thesystem is delivered configured to measure rolls 150mm diameter made from X20C13. In case ofconsiderable deviations from this basic setting this setupcan be changed and stored in the PC. This changecan only be accessed via the password protectedextended programming menu. Return to basic setting ispossible at any time.09.09.1999 Details are subject to change without notice.

So in thethree steps the speed ranges 5 - 50 (x1), 50 - 500 (x10) and 500 - 5000 (x100) pulses per minute are reached.HysteresisThe hysteresis is defined as the difference in speed between the relay switching on and off. Hysteresis tothe low speed switching point can be adjusted by the potentiometer "Hysterese%" from 5% to 100% (hysteresisfactor 1,05 to 2,0).Start DelayAfter start up a motor will not be at rated speed for some seconds. To avoid an unwanted alarm this time canbe adjusted up to 15 seconds. This delay time is adjusted by a potentiometer "Anlauf/sec." or, alternatively,by an external resistance between the terminals 1 and 2. For external adjustment, the internal potentiometermust be set to 15 seconds.Start up delay set by external resistance:Resistance [ohm] 27 K 56 K 120 K 270 K 470 K 1 m 2M2 withoutTime [sec.] 1 2 4 6 8 10 12 15Modes of operationBy means of the four-step slide switch "Funktion" different modes of operation are adjustable in order toguarantee compliance with the safety requirements.Function Modes of control Relay Contact LEDduring start at rated 9 / 10 10 / 11 A Bspeed 12 / 13 13 / 14I speed falls below off off close open •II rated speed on on open close •III rated speed off off close open •IV exceeded on on open close •during starting both LED`s lighten within preselected time • •25.03.1999 Details are subject to change without notice.Proxitron GmbH - Gärtnerstr. 10 - D-25335 Elmshorn - Tel. 04121/2621-0 - Fax. 04121/24404 – E-Mail: mail@proxitron.deD01E
