Low Differential Pressure Transmitters

Select a current loop transmitter for measuring a small pressure difference between two measurement points such as a either side of a ventilation fan, across an air filter or inside and outside a clean room.  Typically these pressure tranmsitter have a 4 to 20 milliamp output scaled over a few millibar or a few inches of water.

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.

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.

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.

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.

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, 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.
