3 wire 4-20mA Pressure Sensors

Current output pressure sensors with a three wire type 4 to 20 milliamp output signal.

Current output pressure transducer for measurement ranges from 0 to 2000 (30000 psi) range up to a maximum range of 6000 bar (90000 psi). All welded wetted parts and ATEX approved electronics for use in flammable gas or dust environments. Primarily used in hydraulic systems, waterjet torching and high pressure petrochemical applications. Accurate to 0.5% full scale output with adjustable zero and span trim via accessible potentiometers.

Ultra low differential pressure sensor for HVAC applications with 4-20mA current loop or amplified voltage output signal in pressure ranges from 0.1 mb up to 1 bar differential.

Differential air pressure sensor with a 10 volt or a 4-20mA output for building ventilation applications. Designed for incorporating into a building HVAC management system to monitor and control the distribution of warm or cool air through ventilation ducts. Pressure ranges from 0 to 1 mbar up to 0 to 1000 mbar differential.

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.
