Explosion-proof switches are mainly used in a variety of applications that require a safe, reliable, and easily disconnectable connection. How to install the explosion-proof switch, the following small series to everyone about the installation of explosion-proof switch.
Connect the multimeter to the output lead.
Unscrew the screw on the top of the controller.
The positive and negative pressure difference is added to 0.15 MPa, which can be read from a standard pressure gauge.
Loosen the set screws.
Use a flat-blade wrench and turn the set point clockwise to adjust the hexagonal groove in the screw so that the set value will become smaller until the switch contact switches at 0.15 MPa.
Adjust the pressure of the calibration table back and forth at 0.6MPa, and check whether the pressure is 0.15Mpa. This value is the lower switching value to be set. Its corresponding upper switching value is between 0.16-0.17MPa.
Tighten the set screws.
Commissioning is complete.
The above is the introduction of explosion-proof switch installation method, we can find out. Explosion-proof switch is mainly used in metallurgy, chemical, petroleum, steel, machinery, refrigeration equipment, refrigeration equipment, water pump differential pressure control, low water level protection differential pressure control, power plant, cement, food, shipbuilding and other industries of gas, steam and water, Oil pressure and other liquid pressure equipment and other industrial equipment supporting agencies, pressure monitoring, alarm, interlock protection, to achieve two automatic control.
