250V Differential Pressure Switch For Air Conditioner

250V differential pressure switch for air conditioner


Description


QAD series air differential pressure switch is widely used for monitoring gas, non-corrosive medium, measuring absolute pressure, gauge pressure and absolute pressure. The medium and ambient temperature is from -20~85°C, and the storage temperature is -40~85°C. The switch pressure should be specified for vertical installation. We recommend using the pipe connection facing down. If the switch is installed horizontally with an AMP connector, the switch value may be 20Pa higher than the actual value.
