Absolute Pressure Transmitters

Current output transmitters for measuring pressure with an absolute reference.  Absolute referenced pressure transmitters genrate a 4mA output signal when the pressure corresponds to a perfect vacuum.  An absolute pressure transmitter is used in applications where the pressure of a gas or liquid is isolated from atmospheric pressure changes, for example when testing a sealed pressure vessel for leaks over a long period of time. 

Versatile low price pressure transducer with a wide selection of electrical and mechanical options to enable the customisation of the sensor to suit most industrial, automation and OEM design installations. A dry cell ceramic strain gauge sensing diaphragm provides a high corrosion resistance to many types of harsh chemical media commonly found in automated industrial processes and machinary monitoring applications.

Stainless steel 316L wetted parts pressure sensor for high pressure ranges from 60 bar (900 psi) up to 600 bar (9000 psi). Used on applications such as hydraulic test benches, presses, injection moulding machines, hydraulic actuation and vehicle hydraulic systems. Accurate to 0.35% FS with options for 0.25% or 0.1% FS. Good long term stability of 0.1% FS over a period of 1 year.

Dual analogue output signal transmitter for simultaneous measurement of media pressure and temperature. Pressure ranges from 100 mbar up to 1000 bar and temperature measuring range from -25 to 100 DegC. To ensure good thermal contact with the media the temperature is measured just behind a flush diaphragm which has sufficient surface area to ensure minimal losses in media temperature at point of measurement.

High precision pressure transmitter with an accuracy of 0.1%FS BSL NLHR and digitally adjustable pressure ranges from 400mb up to 40 bar gauge & absolute

High performance transducer with adjustable scaling for modifying the pressure range for different applications. Ranges from 0-60 bar up to 0-600 bar gauge or absolute. The output signal is accurate to 0.1% of base range or 0.5% with a 10:1 turn-down, and a 14 bit analogue to digital conversion provides a high resolution amplified output. Optional software and interface kit is available for re-ranging the output signal.

Three in one electronic pressure switch, digital pressure gauge and pressure sensor with pressure ranges from 100 mbar up to 600 bar (1.5 to 9000 psi) gauge or absolute.

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.

Combined sensor, electronic switch and digital gauge with an all welded stainless steel flush face diaphragm for measuring the pressure of high viscosity liquids or gases and fluid requiring a high level of cleanliness. Choose measuring ranges from 60 bar up to 400 bar with gauge or absolute reference. Select different sizes of BSP thread for a screw-in type pressure fitting. The integrated digital readout can be configured to read in any pressure units and process pressure limits can be set for controlling external equipment.

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.

Low cost ceramic diaphragm pressure transmitter available on a short lead time. Pressure ranges starting from 1000 mbar up to 0-700 bar gauge or absolute. Electrical signals 4-20mA, 0-5V or 0-10V can be selected. A choice of DIN plug connector or integral cable can be specified for the electical interface.

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.

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.

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.

Process transmitter for measuring vacuum, steam, food, pharmaceutical, oil, gas and other pressure readings necessary for the monitoring and control of bulk production processes. Suitable for deploying in many locations and feeding pressure readings back to the site distributed control system (DCS).
