Air Conditioner Pressure control Switch

Air Conditioner Pressure control Switch

Working Principle:

when the medium(liquid or gas) pressure within the pressure system is above or below the rated security pressure, the dish metal diaphragm within the system jumps instantaneously, thus to push the switch contact to be connected or disconnected through a connecting rod; when the pressure drops to the rated recovery value, the dish metal diaphragm is instantaneously reset and the switch is automatically reset.

Feature:

• Measurement range: 3-667PSI(0.02-4.6Mpa)
• Multiple pressure ports
• CE certificated                                              
• One group switch quantity output control
• Intrinsic safety explosion-proof type
• Conform to the state explosion protection standards
• Flexibly installed and easily used,with no special installation and fixing mode.
• Insert and wire-type electrical connectors can be selected
