Choosing and fitting
Parts of this type are selected by the medium (gas), the switching range and differential, the type of connection (thread or hose spigot), and the contact rating. Before ordering, compare the setpoint range and connection geometry with the existing installation. The differential, or the gap between the setpoint and reset point, must suit the system to avoid unnecessary lockouts.
Signs of failure
Common failure modes for this type include a torn diaphragm, a blocked impulse tube, or a drifted setpoint. These faults often produce lockouts that can be mistaken for ignition problems. Checking the pressure switch, its impulse line, and the setpoint should be part of systematic diagnostics.
