- product introduction:The LF30 pressure switch employs a differential pressure to actuate a precision snap switch at chosen pressure setting. This may be the difference between atmospheric and a negative or positive pressure or between any two given pressures. When a change of pressure occurs between the negative pressure chamber and the positive pressure chamber the main diaphragm activates the snap switch at a pre-determined value.
The LF30 pressure switch is manufactured from selected compound derivatives of polycarbonate & PBT offering exceptional thermal and dimensional stability at elevated temperatures up to 105°C when used in contaminated atmospheres of air, products of combustion, L.P. or natural gas. It has been designed to meet the low pressure, high-temperature specifications of future generations of fanned gas and similar appliances where differential pressures form part of an integrated control system.
Typical Applications:
Detects airflow in forced draught appliances
Signals either positive, negative or zero air movement
Shut down burner in blocked flue conditions
Guards against poor or hazardous combustion
Indicates dirty or inefficient filters
