Water resistant pressure sensor for measuring hydrostatic pressures in the range of 0-0.5 mWC up to 0-100 mWC. An all stainless steel 316L construction with Viton O rings seals and a choice of PUR, PVC or FEP vented cabling. The IMSL is used for measuring groundwater, aquifer, reservoir and borehole water level. The internal silicon strain gauge sensor provides a stable water level reading accurate to 0.1% of span linearity with low hysteresis and repeatability errors.
Hydrostatic Level Ranges: 0.5 up to 0-100 mWC, 0-2 up to 0-10 bar absolute
Accuracy: 0.1% or 0.06% full scale BSL linearity (11-12 bit resolution)
Output Signal: 4-20 mA current loop output and voltage output, mV/V uncompensated
Electrical Connection: IP68 integral cable with a PUR, PVC or FEP jacket.
Pressure Connection: 1/4 BSP male with protective nose cone
Media Compatibility: SS 316L sensor body and diaphragm with Viton O ring seal and PUR, PVC or FEP coated cable
Diameter: 25 mm (1 inch)
Special Features: Low hydrostatic ranges
The IMSL submersible pressure sensor utilises a silicon strain gauge sensing element which offers a very linear accuracy performance over the hydrostatic pressure range with minimal hysteresis and repeatability errors. Silicon strain gauge diaphragms also make it possible to measure very shallow depths without the need for increasing the diameter of the probe.
A wide choice of electrical output signals is available with 4-20mA for use in process plants and utilities, 10V, 5V dc voltage output signals for telemetry or data acquisition equipment and mV/V or 0-2.5Vdc outputs for applications requiring a low power consumption.
