Submersible Pressure Transducers

Watertight volts out transducers for submerging to measure liquid depth/level or underwater system pressures.  These transducers can be submerged underwater as part of a permanent installation such as in a borehole or a liquid storage tank. No installation mounting is required for these submersible transducers, each is fitted with a cable designed to support the weight of the transducer and cable, although it is recommend to lower inside a stilling well where the liquid is moving such as in tidal water or groundwater pumping installations.  Submersible pressure transducers are typically vented to compensate for ambient pressure changes when measuring liquid depth, but non-vented versions are also available for applications where the cable is not brought to the surface. 

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.

Submersible waste water level sensor with optional intrinsic safety certification for monitoring the level of sewage and effluent in water treatment plants. Available in level ranges from 4 up to 250 meters of water gauge.

Absolute referenced hydrostatic depth sensor with an IP68 sealed electrical interface, stainless steel 316L, Duplex or PVC housing and a mV, amplified voltage or current output. Available in depth ranges from 1 to 10 bar absolute.

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 Low Range waste water level transmitter with intrinsically safe option for monitoring the level of sewage and effluent in water treatment plants. Available in level ranges from 0.4 up to 100 meters of water gauge.

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.

Analogue output sensor for immersing in seawater to determine depth or change in water level by measuring hydrostatic pressure. This sea depth probe has a Marine bronze housing and Ceramic diaphragm for protection from saltwater corrosion. Select fixed ranges from 10 metres (33 feet) up to 100 metres (328 feet) depth in a number of analogue output configurations including low voltage strain gauge, amplified voltage and current loop output. Also suitable for use in brackish and inland tidal water or any other application where there is the risk of corrosion form a saline liquid.
