316 stainless steel pressure sensors

15 May 2018

Variohm Euro Sensor has expanded its range of pressure sensors with the new and robust EPT7100 series featuring 316 grade stainless steel wetted parts and an integral Packard connector for excellent durability and convenient installation.

The sensors offer a choice of four hermetically sealed pressure ports and five standard pressure range options from 0.01 to 10 bar. The EPT7100 is suitable for gas or liquid pressure measurement for on- and off-highway automotive, HVAC, compressors, industrial hydraulics and more.

The new sensor is based on a well proven piezo-resistive sensing element and the 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 °C 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 5 VDC 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 to 3.5 bar this version includes all of the features of the full range model.
