Product Items

PD33X High Accuracy Differential Pressure Transmitter

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.

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

PD33X Digital Differential Pressure Sensor

High precision differential pressure transducer with an accuracy of 0.1% full scale including temperature errors over +10 to 40 deg C. Available in pressure ranges from 1 to 30 bar differential with a RS485 digital interface as standard plus an optional USB or RS232 converter cable for connecting to a desktop or laptop computer.

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.

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

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.
