1.This switch is used in air pressure sensing.
2.This switch has application to sensing of exhaust gas in oil, gas boiler and fan heater.
Features
1.This switch operates by a positive pressure and negative pressure, a differential pressure.
2.This switch is operated to low pressure of 4 to 30mmH2O and a
user is able to request necessary pressure point. (4~30mmH2O differential pressure(ΔP)±3mmH2O)
