Low Differential Pressure Transducers

Find a low pressure range dp transducer for measuring draft pressures in ventilation systems or air extraction systems.  These transducers have two ports for connecting either side of a ventilation fan, filter or valve.  Applications include building management systems, industrial air handling, clean room positive pressure and air scrubbing.

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.

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

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.

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
