Pressure Sensors Approved for Intrinsic Safety

Intrinsically safe pressure sensors certified for use in potientially flammable environments with IS barriers

Stainless steel pressure transmitter with ranges from 100mbar up to 40 bar gauge or absolute with optional accuracy ranging from the standard 0.35% FS up to 0.1% FS. Special options such as ATEX approval, SIL approval and compound ranges are also available.

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.

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.

Pneumatic pressure sensor for measuring very low gauge reference pressures with ranges starting from 10 mbar (4 inH2O) up to 1000 mbar (400 inH2O) gauge. Ideal for use on pneumatic control systems, heating, ventilation and air conditioning systems (HVAC) and computer equipment rooms.

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.

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.

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.

Low range three in one pressure switch, pressure indicator and pressure sensor for use on pneumatics and vacuum technology in a choice of ranges starting from 0 to 10 mbar gauge (4 inH2O) up to 0 to 1000 mbar gauge (400 inH2O) plus a 0 to -1000 mbar vacuum range. Compatible with gases, compressed air and low viscosity non-aggressive fluids.

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.

High precision compact wet wet differential pressure transmitter with digitally corrected 4-20mA current loop or amplified voltage output signal in pressure ranges from 1 up to 30 bar differential.

Passive compensated pressure transducer with a four arm semiconductor Wheatstone bridge circuit which produces a 100 millivolt with a 10 volt excitation. Pressure ranges from 0-100mbar up to 0-1000bar gauge or absolute. The silicon sensing chip is totally isolated from the media by an oil filled stainless steel 316L capsule with isolation membrane. This sensor is ideally suited for high frequency response applications since the output is only limited by the natural response of the silicon sensing capsule.

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). Includes HART protocol interface, 10:1 adjustable range scaling and ATEX intrinsic safety as standard, with options for 300degC media temperature and integrated local digital indicator. Available in pressure ranges from 0-400mbar up to 0-600 bar gauge or absolute, and compound ranges from -0.4 to +0.4 bar up to -1 to 10 bar gauge.
