Description
The Kromschroder 74214174 Gas Pressure Switch is used to measure the pressure of the gas in an HVAC system continuously. It is fitted with a diaphragm and spring which is sensitive to pressure changes. If the gas pressure is higher or lower than the set value, the switch closes an electric contact which in turn causes a safety action such as cutting off the supply of gas or signaling the control system. This makes certain that the system is working under a safe pressure range, avoiding gas escape, inadequate combustion, or equipment destruction. The switch is adjustable, the proper pressure to be set to ensure safe and efficient functioning.
