It is used to monitoring overload pressure of the air, noninflammable and noncorrosive gas,vacuum degree and diffe-rential pressure. Can be applicable to the following sites:
The air filter and ventilator
The industrial refrigerating air circulation
The electric heater overheating protection
The air flow in vent pipe
The heat exchanger freeze-proofing protection
The monitoring of the pressure and level of the storage tank and pressure vessel
1.The air differential pressure value can be set by adjusting the knob, no need to connect the pressure meter. Return
difference controlling can be achieved by adjusting “ –“ screw.
2.The differential pressure value indicating the vertical installing, when horizontal installing, the true value is higher a-bout 20Pa than the setting value.
