Description
The Crandall 2252-501-CSS Pneumatic Temperature Transmitter 40–140°F is a duct-mounted averaging temperature sensor designed for use in pneumatic HVAC control systems. This transmitter measures air temperature across a 20-foot averaging element and outputs a proportional pressure signal (3 to 15 PSIG) for building automation or pneumatic logic controls. Engineered to Crandall specifications, it delivers reliable temperature sensing and stable control responses over its rated temperature range. Ideal for technicians and controls contractors, it helps ensure accurate environmental monitoring and consistent HVAC performance in commercial and industrial settings.
