Diaphragm pressure switch SPDT&DPDT 1/2NTF

Platinum resistance temperature sensor has high precision, good stability and wide application temperature range. It is the most commonly used temperature detector in medium and low temperature area (- 200-650 ℃), which is widely used in industrial temperature measurement.

When the pressure in the system is higher or lower than the rated safety pressure, the disc in the sensor moves instantaneously, and the switch connector is pushed to connect or disconnect through the connecting guide rod. When the pressure drops or rises to the rated recovery value, the disc resets instantaneously, and the switch resets automatically, or simply when the measured pressure exceeds the rated value, the free end of the elastic element displaces, Push the switching element directly or after comparison to change the on-off state of the switching element, so as to control the measured pressure.

The elastic elements used in the pressure switch include single coil spring tube, diaphragm, diaphragm box and bellows.

Diaphragm pressure switch is one of them.
