Sensitive Differential Pressure Switch for Air
Ref: P233A-4-PHC
£54.30 excl. VAT £65.16 inc. VATThis differential pressure switch is used to sense flow of differential air pressure.
Typical applications include:
- Detect clogged filter
- Detect frost or ice build-up on air conditioning coils
- Air proving in heating or ventilation ducts.
- Maximum airflow controller for variable air volume system.
- Detect blocked flue or vent
- Monitor fan operation
Description:
This switch senses a change in the differential pressure.
drop across a restriction) as the airflow changes.
The differential pressure is applied to the two sides of a diaphragm in the control.
The spring-loaded diaphragm moves and actuates the switch. pressure connection and leaving the lowpressure port open. Or to detect a vacuum by using only the low pressure connection andleaving the high-pressure port open to ambient pressure.
P233A-4-PHC range: 50 to 400 Pascals
