Low Pressure Differential

  • Low pressure ranges from 0-5 mbar
  • Available for gauge reference or bi-directional measurement
  • Durable designs for industrial and commercial installations
  • ATEX/IECEx option available

Our low range air differential pressure transmitter provides an accurate solution for low pressure sensing with ranges available from 0-5 mbar to 0-1,000 mbarDP. Incorporating the latest silicon sensor and electronics technologies, these 4-20 mA transmitters are fully temperature compensated for unrivalled stability at very low pressure.

Housed in an RFI shielded wall mountable box for EMC protection, these transmitters combine precise measurement for control at very low pressures, with the robustness and flexibility for industrial and commercial installations. An optional heavy-duty aluminium die-cast housing is available for the harshest environments.

Access to screw terminal electrical connections and to zero span potentiometers is by removing the front covers, making installation and on-site adjustment. Cable entry is through a compression seal gland, or optional M20 conduit fitting. Standard pressure connections are to push-on hose fittings for 4mm ID hose. Ranges available from 0-5 mbar to 0-1,000 mbar in DP, gauge reference or bi-directional. Ultra-low pressure ranges from 0-25 Pa are also available.

Standard pressure ranges:

0-5 mbar; 0-10 mbar; 0-20 mbar; 0-50 mbar; 0-100 mbar; 0-250 mbar; 0-500 mbar; 0-1,000 mbar (other options available)

Typical applications include:

  • Flow measurement with pitot tubes
  • Orifice plates and mass flow meters
  • Static pressure measurement and control
  • Combustion chambers and clean room environments
  • Air or gas applications requiring reliable ultra-low differential pressure measurement
