What Are Field-Bus Systems?A field-bus system is a data network with the objective to receive data from a production process, exchange data betweendevices or machines, control steps or processes in production. Data transmission happens serially with digital signals(equivalent to Internet data transmission.)The most basic design of such a data network is a 2-wire cable with various individual sensors (e.g. Pressure transmitters),actors (e.g. solenoid valves), controllers, periphery units, and control units (e.g. PLC, industrial PCs) connected at any point.BUS participants need a suitable interface, which transfers flow of data.

Pressure SwitchesEDS 300 - ShipbuildingAbout EDS 300 Pressure Switches:The EDS 300 is a compact, electronic pressure switch with digital display. The pressuremeasurement is based on a thin film strain gauge sensor cell in stainless steel. All partsin contact with the fluid are in stainless steel, and are welded together. Since no sealsare required in the sensor chamber, leakage is eliminated.Two relay switching outputs with N/O function and an additional analog output signal (4to 20 mA) enable the pressure switch to be incorporated into the most modern controlconcepts. The switching points and the corresponding hysteresis can easily be adjustedvia the keypad.For optimum adaptation to a particular application, the unit has many additionaladjustment parameters, e.g. switching direction of the relays, switching delay times.Areas of application are pressure or maximum value monitoring on marine transmissions,diesel engines, pumps and general hydraulic and pneumatic systems.Technical Details:Input DataMeasuring ranges-14 to 75, 150, 1000, 3000, 6000, 9000 psi-1 to 5, 006, 016, 040, 100, 250, 400, 600 barOverload pressure200, 300, 3000, 7000, 11000, 13000 psi15, 15, 32, 80, 200, 500, 800, 900 barBurst pressure400% FSOutput DataAccuracy (display, analog output)≤ ±1% FS max.Repeatability≤ ±0.5% FS max.Temperature drift≤ ±0.3% / 10 K zero point max.≤ ±0.3% / 10 K range max.Analog output4 to 20 mA, ohmic resistance ≤ 400 ΩSwitching OutputsType2 relay contacts (N/O)Switching voltage10 mV to 60 V (AC or DC)Switching current0.01 mA to 1AMaximum switching output30 W / 30 VA(for inductive load, use varistors)Life expectancy20 million (min. load)0.5 million (max. load)Reaction timeapprox. 10 msAmbient ConditionsTemperature range of medium-13° to 176°F (-25° to 80°C)Ambient temperature range-13° to 176°F (-25° to 80°C)Storage temperature range-40° to 176°F (-40° to 80°C)Nominal temperature range-14° to 158°F (-10° to 70°C)markEN 50081-1, EN 50081-2EN 50082-1, EN 50082-2Vibration resistance5 to 25 Hz: 3.2 mm25 to 500 Hz: 4 gOther DataSupply voltage20 to 32 VDCElectrical connectionplug to DIN 43651 (6 pole + earth)Current consumptionapprox. 100 mASafety type IP 65Hydraulic connectionG 1/4 A male, (torque rating approx. 15 lb-ft)SAE 4 female thread (torque rating approx. 6 lb-ft)Parts in contact with fluidstainless steel, FPM sealMaterial of housingtube: stainless steelkeypad housing: PA6.6 Gf30Display4-digit, 7 segment LED, redWeightapprox. 300 gApplications:Approvals:American Bureau of ShippingNo.: 00-ES 19976-XLloyds Register of ShippingNo.: 00/20048Det Norske VeritasNo.: A-7710 (895.10)Germanischer LloydNo.: 15519-00HHBureau VeritasNo.: 10343 /A0 BV25Electronics Catalog

Flow Rate SensorsEVS 3100 Flow Rate SensorAbout EVS 3100 Flow Rate Sensors:The EVS 3100 series flow rate sensors are designed to accurately measure theflow-through volume of fluids in hydraulic systems. The unit uses a stainlesssteel turbine wheel internal to the construction, which converts the media flowinto a 4 to 20mA output signal.The in-line mounting design allows for most accurate and up to date flowmeasurements. The EVS 3100 also offers two additional hydraulic ports toaccommodate additional sensors, ex. temperature and pressure transducers.The design of the flow meter incorporates a lightweight aluminum housing withaccurate and stable measuring elements.The unit uses the Woltmann Turbine principle to measure flow. The fluid entersthe housing and passes through straightening blades, which assist in stabilizingthe media into a laminar flow. The stainless steel turbine wheel is rotated by themedia flow, which then influences the magnetic field of the inductive receiverwith the passing of each turbine fin. The inductive receiver is the sensing elementof this flow meter. This influence produces a voltage pulse in the receiver, whichit then converts into a 4 to 20mA output signal.This design provides precise data within the entire measurement range of theunit, and is relatively tolerant against minimal, gritty contamination. The meteralso allows for exceeding flow of up to 50% of the maximum range for shortperiods of time.Technical Details:Supply VoltageSignal OutputmarkTemperature of MediaAmbient TemperatureMedia - EVS 3100EVS 3110Permissible Viscosity RangeCalibrated at - EVS 3100EVS 3110Accuracy ClassMeasuring Ranges/Operating PressureEVS 3100-1EVS 3100-2EVS 3100-3EVS 3100-5Electrical ConnectionMechanical Connection/Torque RatingEVS 3100-1EVS 3100-2EVS 3100-3EVS 3100-5EVS 3100-1-SAE 37EVS 3100-2-SAE 37Additional Connectionson Housing10 to 32 V DC4 to 20 mA, 2 conductorEN 50081-1, EN 50081-2,EN 50082-1,EN 50082-2-4° to 194°F (-20° to 90°C)-4° to 158°F (-20° to 70°C)hydraulic oilwater1 to 100 cSt30 cSt5 cSt≤ 2% of the instantaneous value6 to 60 l/min / 400 bar (1.6 to 15.9 gpm / 5800 psi)40 to 600 l/min / 315 bar (10.6 to 159 gpm / 4567 psi)15 to 300 l/min / 400 bar (4 to 79.3 gpm / 5800 psi)1.2 to 20 l/min / 400 bar (0.26 to 5.28 gpm / 5800psi)4 pole Binder plug 714 M18x1G 1/2 female thread / approx. 130 NmG 1 1/2 female thread / approx. 600 NmG 1 1/4 female thread / approx. 500 NmG 1 1/4 female thread / approx. 60 NmAvailable with SAE thread using adapters.Thread is 37° flare.2 x G 1/4 female ports for pressureor temperature sensorsApplications:Approvals:47Electronics Catalog

Therefore, the majorityof commercially available sensors with standard output signals can beconnected and evaluated.• As well as the current measured values, the unit also records the minimumand maximum values, in addition to the differential between twosensors of the same type.12...30 V DC, charging current max. 500 mA constantsupply possible charging time approx. 3 hours whenbatteries flat4 x NiMH batteries 1.2 V, Mignondepending on the type of sensors connected e.g.:with 2 HYDAC pressure transmitters (4 to 20 mA signal)approx. 10 hours operation possible10° to 40°CGeneral:0 to 70% relative, non-condensingapprox. 500gThe HMG 2020 generally distinguishesbetween three measurement options:1. Normal measurementPurely a display function wherethe measured values are displayedimmediately.Ex: When HMG is measuringwith pressure sensors to act asa digital gauge.2. Curve measurementThe measured values are displayedand simultaneously storedcontinuously in the internalmemory. The courses of thecurves can be printed out on theprinter as soon as measuring hasstopped, or transferred to a PCand viewed with the software.3. Log measurementThe measured values are displayedand can be stored as logentries in the internal memory.This method of measurement isused primarily for long-termmeasurements (e.g. one week, onemonth, one year etc.). The log entriescan be printed out on a printeras soon as measuring has stopped,or transferred to a PC.The internal memory can store upto 50 different curves and logs with250,000 measured values in total.To optimize your measurements theunit has a wide variety of additionalfunctions:• Choice of languageThe user may define which languagethe unit will display thedata and parameters.49Electronics Catalog
