Differential pressure monitor LGW ... A2, LGW ... A2P is adjustable for different combustion equipment pressure monitoring devices. Set for the use of pressure to change the rated pressure of the actual value of the occasion, the pressure difference can be used to monitor traffic circulation loop open, close, and conversion. Ratings are adjusted with the scale of the adjustment wheel. LGW ... A2P with lower detection key. 
 Monitor pressure in the combustion, ventilation and air conditioning technology for pressure monitoring. 
 For air, smoke, gas and other non-corrosive gases. 
 Does not apply to combustion gases.
