Gas expansion thermostat 23

mechanical

DESCRIPTION
The air expansion thermostat 23 is a purely mechanical device designed to detect ignition and the rapid temperature rise that can precede a fire. Its thermal‑sensitive element deforms under heat, compressing the internal air chamber to generate a pneumatic signal that actuates pilot cylinders and downstream pneumatic actuators. The unit is supplied/compatible with a protective cage for installation in exposed locations.
