High-accuracy heavy-duty pressure sensors with 1% total error band accuracy accomplished by marrying a high performance ASIC to a very stable, field-proven polysilicon, thin-film pressure sensor. These sensors are intended for use in demanding industrial and off-highway equipment.The Hydraforce Model ERP pressure sensors are high performance instruments intended for use in off-highway and industrial applications where the process media is compatible with the 17-4PH stainless steel sensor material and the 304 SS process connection. Mechanical Installation Guidelines:EnvironmentalThe ERP pressure sensors can be stored and used within the temperature limits of -40°C to 125°C (-40°F to 257°F). Ingress protection ratings of the units are IP67 standard, but dependent on the electrical termination specified for special models. MountingThe ERP pressure sensors require no special mounting hard-ware and can be mounted in any orientation with negligible position error. Although the units can withstand considerable vibration without damage or significant output effects, it is always good practice to mount the sensor where there is mini-mum vibration. For units with NPT type pressure fittings, apply sealing tape or an equivalent sealant to the threads before installing. When installing or removing the unit apply a wrench to the hex wrench flats, located above the pressure fitting. DO NOT tighten by using a pipe wrench on the housing. A 27 mm (11/16 inch) wrench can be used on the wrench flats of the hex. Electro-Magnetic InterferenceThe circuitry of the ERP pressure sensors is designed to minimize the effect of electromagnetic and radio frequency interference. To minimize susceptibility to noise, avoid running the termination wiring in a conduit which contains high current AC power cables. Where possible avoid running the termina-tion wiring near inductive equipment.Field AdjustmentsThe ERP pressure sensors are precisely calibrated and tem-perature compensated at the factory to ensure long and stable performance. There are no field accessible adjustments on the sensors.Electrical InstallationPlease refer to the performance ratings on the previous page for power supply requirements and for appropriate wiring proto-col based on the particular output signal and electrical termina-tion features of the unit being installed.
