High accuracy pressure sensing with corrosion resistance

The new sensor is based on a well proven piezo-resistive sensing element and latest ASIC circuitry which does not rely on O-ring sealing or silicon oil. This combines with IP67 environmental rating, additional EMI / RFI protection and MIL-STD shock and vibration specifications. Suitable for gauge, absolute and sealed gauge pressure measurement (gauge only on 0.01 pressure range), the EPT7100 series offers a compensated temperature range between -20 to 85°C where the tolerance band including thermal effects is within ±1% of span.

Error-free operation is guaranteed for media or environment temperatures between -40 °C and 125°C. Accuracy at room temperature is ±0.25% BFSL. The output signal is 0.5-4.5 VDC from a 5VDC supply. The new sensor is available as a stock delivered item with an M10 x 1 pressure port and a zero to 3.5 bar pressure range.

The EPT7100 is also available specifically configured for use in motorsports as an absolute pressure map sensor. With a pressure range from 0-3.5 bar this version includes all of the features of the full range model.

The new sensor series is part of a wide range of position, force, pressure, load, and temperature sensor technologies available from Variohm EuroSensor - a manufacturer, distributor and supply chain partner providing complete sales and application support for demanding measurement applications across industry, construction, agriculture, motorsports, research and more.
