Features

  • They feature an integral pressure transmitter with dead-ended input ports, eliminating maintenance and inline filter requirement while preventing chances of sensor contamination.
  • These devices produce an output of 0 to 1.5 in W.C. sensor range, thus satisfying the requirement of any terminal box applications.
  • Their 0.5 to 4.5 VDC output is supported by a wide range of HVAC controllers.
  • These devices require no warmup period, allowing them to be commissioned immediately after powering up.
  • Their capacitive sensor technology delivers long term stability and accurate readings / output.
  • They have a compact design for easy installation.

Working Mechanism

  • These controls measure differential pressure for determining the air velocity to calculate the airflow, generating a proportional voltage signal.
  • The generated voltage signal is read by the VAV type controllers which gets converted to airflow.
  • These controls have 3 terminals, one is connected to power, second to ground and third to control output & controller input.

Standards and Approvals

  • UL
  • CSA

Frequently Asked Questions

How do differential pressure transmitters work?

These transmitters measure the difference between two pressures using a reference point known as low side pressure and compare it to high side pressure.

How to mount these differential pressure transmitters?

A mounting kit is used to mount these transmitters on VAV controllers.

Do these controls need to be calibrated after installation?

Users need to perform the zero calibration. The rest of the calibration is performed within the connected controller itself.
