CLEVELAND CONTROLS Switch Air Sensing


Cleveland Controls air sensing switches detect changes in air pressure and use that information to control HVAC/R systems. They help monitor and regulate airflow, filter conditions and overall system performance. These switches can activate fans, initiate safety shutdowns in case of pressure im...balances, control damper operations and trigger alarms in case of critical pressure deviations.Read more

Working Mechanism

  • Clevelend Controls air sensing switches consist of a diaphragm that reacts to changes in the air pressure.
  • When the pressure reaches the designated set point, the switch gets triggered and makes or breaks an electrical connection.

Features

  • Cleveland Controls air sensing switches have an operating temperature range of -40 to 190 degrees F and can handle pressures up to 1 psi.
  • They are field adjustable to a set point of up to 12-inch water column.

Standards and Approvals

  • CE
  • CSA
  • UL
