Introduction:
SA102 series differential pressure switches can sense the pressure difference, vacuum, over pressure, poor flow of the incorrosive gas.
Conventional applications include:
+ Monitoring Filters blocked Alarm Device
+ Monitoring air blower running status.
+ Monitoring air of ventilative pipelines
+ Controlling the largest gas flow of variable gas volume
+ Monitoring the gas of combustion furnace.
