Description
The Kromschroder 84447351 Gas Pressure Switch is a diaphragm-based control component designed to monitor and respond to changes in gas or air pressure within burner and combustion lines. It operates using an adjustable setpoint mechanism with a handwheel, triggering a switching contact when pressure rises or falls beyond the defined limit. The unit is used for pressure supervision, safety cutoff and control signaling in burner management and fuel delivery arrangements. It is typically applied in gas-fired heating and combustion setups to ensure safe operating conditions and pressure monitoring in HVAC systems.
