Pressure switch

LGW10A2

Pressure switch
Lgwa2 / A2p / A4 is a differential pressure monitoring equipment mainly used for air, flue gas and waste gas. By adjusting the rated (action) pressure value of the pressure switch, the pressure in the actual situation can be controlled. It is mainly used for opening, closing and conversion of flow circulation circuit. The rated pressure of the pressure switch can be adjusted by rotating the dial.
A detection key is set at the lower part of llgwa2p.
 
characteristic:
Simple installation, small size and light weight
The scale is accurate, convenient and time-saving
 
Application:
Llgwa2 / A2p / A4 pressure switch is mainly used for pressure monitoring in combustion system, ventilation system and air conditioning system.
Applicable to air, flue gas, waste gas and other non corrosive gases, not applicable to industrial gas.
 
Function:
This pressure switch can work in the range of overvoltage or undervoltage
The pressure changes on both sides are sensed through the membrane, so as to control the action of the internal small switch.
No other auxiliary energy is required during operation.
 
Switch characteristics:
The pressure switch responds by monitoring changes in pressure on both sides of the membrane.
The circuit is closed, disconnected or switched when it exceeds or falls below the set rating.
 
Detection key llgwa2p
Llgwa2 has a pressure detection key, which can be used to check the safety performance.
If there is pressure at G1 / 4 connector, press the test button switch to release the internal pressure. Thus, the partial pressure at the lower part of the film decreases, and the reed of the pressure switch will change from no contact to NC contact.
When the detection key is released, the partial pressure at the lower part of the membrane rises. The switch reed returns to its original position.
