IP54 Adjustable Pressure Switches CE Adjustable Air Compressor
Pressure Switch
Description
The pressure switch adopts high-precision, high-stability pressure
sensor and transmission circuit, and then uses the special CPU
modular signal processing technology to realize the detection,
display, alarm and control signal output of the medium pressure
signal. Pressure switches can be widely used in petroleum,
chemical, metallurgy, electric power, water supply and other fields
to measure and control the gauge pressure and absolute pressure of
various gases and liquids. It is an ideal intelligent measurement
and control instrument for industrial sites.
Q series single pressure controls can be not only used in
fluorinated refrigerant, but also in the air and liquid(allowed
liquid temp. -20 to 120°C)
Adjustable range and differential settings
Renovated SPDT micro-switch ensures the reliable switch function
Flexible mounting bracket suits various kids of application
Upper lid is optional (IP44)
Various connections are available on request
Automatic and manual reset version
The material of bellows is copper and pressure interface is brass
Several models available in drip-proof enclosure for marine
applications or in explosion-proof enclosure for special
applications
CE approval
