Groundwater Pressure Transducers

Measure the level of groundwater in a borehole with these voltage output pressure transducers.  Each transducer is waterproof protected and designed to be lowered into a bore hole from the ground surface. The volts output is linear and proportional to the measured water depth pressure.  A vent tube is provided running along the inside of the signal cable to provide atmospheric pressure reference. 

Economical IP68 protected sensor with stainless steel 316L housing and Ceramic strain gauge sensing diaphragm for measuring liquid depth pressure or the pressure in a submerged pipe or vessel. Measure hydrostatic pressure from from 0 to 10 mWC (33 ftWC) up to 0 to 100 mWC (330 ftWc) and convert reading to a millivolt, current or voltage signal output. The Ceramic diaphragm has a high chemical resistance to media such as leachate and seawater, and the housing can be upgraded to Duplex stainless steel if necessary for extra material protection. A PUR coated cable is fitted as standard, but for additional chemical protection an FEP coated cable can be supplied.

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.

IP68 protect pressure sensor for monitoring fresh water level to depths of 100 metres. This stainless steel drinking water compatible level sensor has been assesed and certified by the Water Regulations Advisory Scheme (WRAS) for compliance with the UK water regulations. The materials and fittings used in the mechanical construction of the IWSL water level sensor meet the standards required by the water supply byelaws of England, Wales and Scotland.

Submersible level transmitter for measuring liquid level with a 4-20mA current loop or a 0-10V voltage output plus optional ATEX approval for instrinsically safe use in hazardous areas in ranges from 1mH2O up to 250mH2O.
