Product Items

41X Low Range Digital Output Pressure Sensor

Low pressure sensor with a USB, RS232 or RS485 digital output interface for measuring low range gauge or differential pressures. A choice of three pressure ranges are available: 10, 20, 30, 50, 100, 200 or 300 mbar, each with an accuracy of 0.1% full scale over a temperature of -20 to +80 DegC

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.

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.

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

LEO Record Capo Low Pressure Data Logger

Battery powered data logger for measuring and recording low range pressures. Designed for use in industrial environments with IP65 environmental protection and optional intrinsic safety. Available in pressure ranges from 10 mbar (4 inH2O) up to 300 mbar (120 inH2O) vented gauge.

LMK351 High Overpressure Flush Level Transmitter

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.

PD39X High Differential Pressure Transmitter

High pressure differential sensor that has high over-pressure with 4-20mA current loop or amplified voltage output in scaleable differential ranges from 3 bar up to 300 bar differential

PD39X Twin Absolute Digital DP Sensor

Digital pressure sensor with 3 separate channels for measuring P1, P2 and DP readings plus 2 temperature channels measured on the sensing diaphragm which is in close contact with the media. Base pressure ranges from 3 bar up to 300 bar with high accuracy.

XMD Process Plant DP Cell Differential Pressure Transmitter

Rangeable DP Cell current loop process transmitter for monitoring differential pressures in a heavy duty process plant environment. The XMD has a standard process configuration with kidney flange mounting arrangement and large accessible electronic housing. Other features include ATEX intrinsic safety or flameproof, linear or square root extraction 4-20mA output, HART communications, 10 to 1 turndown ranging, LCD readout and 130 bar overpressure protection on one side.
