4-20mA Output Transmitters - Water Level

Water level pressure transmitters with a robust current loop output for use in process plants and with process instrumentation. 

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.

Level pressure sensor with semi-flush ceramic diaphragm and stainless steel or PVDF wetted parts for aggressive corrosive media in ranges from 4mH2O up to 600mH2O gauge or absolute.

Three in one hydrostatic level switch, digital level gauge and level sensor with level ranges from 1 mWG up to 600 mWG (3.3 to 1969 ftWG).

Measure vacuum, positive gauge and absolute pressures from -1 bar (-15psi) up to 40 bar (600psi) with this all in one electronic switch, gauge and sensor. Designed specifically for use in the food, drink and biomedical industry for measuring process pressures and vessel contents. Choose dairy pipe or clamp type sanitary process fittings and select a food grade oil fill as the diaphragm isolation fluid. For pharmaceutical installations requiring hazardous dust protection the instrument includes the option for ATEX intrinsic safety.

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.

Robust cable junction box for terminating vented electrical cable from a 2 wire submersible hydrostatic level transmitter. The inside of the IP66 sealed box is vented to the ambient outside air via a PTFE filter to ensure the level sensor is properly vented to compensate for atmospheric pressure.

IP68 sealed hydrostatic level transmitter with a 17mm diameter for lowering into ground water boreholes for environmental monitoring of water level. Available in level ranges from 6 up to 200 metres of water gauge (650 ftH2O gage) with an accuracy of 0.5% full scale.

Flush capacitive ceramic pressure sensor for measuring corrosive and viscous liquid level from levels 0.4 metres of water up to 200 mH2O. This screw-in fluid level transmitter features high overload rating up to 50x and options for all plastic wetted parts.

Marine approved level transmitter with 4-20mA current loop output for measuring the level of contents inside a ships ballast, fuel, liquid cargo or wastewater tanks with optional all CuNiFe construction for sea-water compatibility in ranges from 0.4 mH2O to 200mH2O gauge or absolute.

Submersible stainless steel pressure transmitter ideal for geotechnical surveying with a 19mm diameter for measuring hydrostatic water level in bore-holes. This small diameter level sensor has level ranges from 1 up to 250 metres water column and a 4-20mA current loop output signal.

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.
