A sensitive differential switch is a sensitive single pole switches that can be used as pressure or vacuum switches, or as differential pressure switches.
Differential switches monitor the difference between two systems. Sensing a low range of pressure, these single pole single throw differential switches monitor air pressure in sensitive environments and sense when low pressure occurs. Sensitive differential switches are weatherproof and explosion proof can be factory set or adjustable simplified calibration.
Presair pressure switches make electrical contact when a certain set pressure has been reached on its input.
By providing on/off switching from a pneumatic source, Presair pressure switches deliver critical benefits:
Safe and Convenient: Remote operation with complete electrical isolation. UL Recognized.
Economical: Costs less than conventional controls
Accurate: Highly stable with good repeat accuracy. All switches are 100% tested at high and low settings and at proof pressure.
Reliable: Minimal moisture absorption and maximal dimensional stability.
