Product Items

41X High Precision Low Range Pressure Transmitter

High precision pressure transmitter for measuring very low vented gauge reference or differential air pressures. Each presssure range can be adjusted to scale the 4-20mA or 0-10 volt output signal from 10 to 100% of the base range. Designed for measuring pressures across air filters, ventilation fans and valves on HVAC and pneumatic systems.

DDS High Over-Pressure Differential Pressure Sensor

Differential pressure transmitter with high over-load capability for measuring low differential pressures from 8mb up to 6 bar differential.

DMD331 Compact Differential Liquid Pressure Sensor

Wet wet differential pressure sensor with a high overpressure rating on both positive and negative side port for protection against accidental diaphragm damage. The DMD 331 has 6 nominal pressure range from 0-0.2 bar up to 0-16 bar differential and each range has a choice of sub-ranges which can be selected depending on the required level of overpressure rating. The differential pressure signals can be transmitted as linear 4-20mA or 0-10Vdc analog output.

DMD341 Compact Differential Air Pressure Sensor

Small size dp sensor for measuring differential air pressure on HVAC, compress air and pneumatic control systems. The DMD341 is used to measure pressures in the range of 0-6 mbar up to 0-1000 mbar differential. An output signal of 4-20mA, 0-20mA or 0-10Vdc can be chosen to suit the signal conditioning of most air handling management systems.

DMP331 Precision Pressure Transmitter

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.

DMP331P Hygienic Flush Pressure Transmitter

Sanitary pressure sensor wth exposed diaphragm with no crevices for high temperatures up to 300 Degrees Celsius in ranges from 100mb up to 40 bar gauge or absolute

DMP343 Low Range Pneumatic Pressure Sensor

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.

DPS Low Differential Pressure Transmitter

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.

DPS200 HVAC Differential Pressure Transmitter

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.

DRS Low Differential Pressure Transmitter

Low range differential pressure sensor with rangeable 4-20mA current loop or amplified voltage output signal in pressure ranges from 1.6mb up to 6 bar differential

DS200P Sanitary Low Range Pressure Gauge, Switch and Sensor

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.

DS210 Combined Low Pressure Switch, Indicator and Sensor

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.

IMP Low Cost Pressure Sensor

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 machinery monitoring applications.

IMPLR Low Range All Stainless Steel OEM Pressure Sensor

Low cost sensor for measuring small pressure ranges from 0-50 mbar (10 inH2O) to 0-1000 mbar (15 psi) of liquids or gases. Choose from a full list of outputs, electrical, connectors and accuracy specs to meet your OEM custom product integration requirements.
