Crouzet 81505150 Pneumatic Pressure Switch

Crouzet 81505150 Pneumatic Pressure Switch monitors air pressure in pneumatic circuits and provides a switch output when the sensed pressure lies within a 0.1–2.5 bar range. The device carries the part number 81505150 and is used in industrial control applications where a pressure threshold must be detected to start or stop equipment. The 0.1–2.5 bar range describes the pressures at which the switch will operate, guiding proper pairing with components such as compressors, regulators, actuators, and control valves in automation systems. Typical uses include triggering a control circuit, signaling a controller to change operation state, or interlocking safety features when system pressure crosses the set range.
