The differential pressure switch is preferably mounted with the diaphragm in a vertical plane , unless the device is set or calibrated for horizontal mounting as on special customer models. On these models the mounting position is indicated on the side of the control .It may be fastened directly to the duct, heater or panel as long as the mounting surface has minimal or no vibration .Pressure connections are marked +(high pressure ) and - (low or static pressure) .For more information, please read the diagram on the side of the control.

 

Possible fields of application include:

* Monitoring air filters and ventilators
* Monitoring industrial cooling-air circuits
* Maximum air flow controller for variable air volume systems
* Overheating protection for fan heaters
* Monitoring flows in ventilation ducts
* Controlling air and fire-protection flaps
* Frost protection for heat exchangers
* Air proving in ventilation ducts
