Honeywell Proportional Temperature Controller - T991A1350/U

The Proportional Temperature Controller by Honeywell offers a set point temperature range of 55 to 175 degrees Fahrenheit. It incorporates a copper averaging sensor element, presented in a 7/64 inch diameter x 24-foot long bulb size. It's structured with one 135 ohm potentiometer and a 24-foot capillary length for optimal functioning.

The controller is distinguished by its fast response models specifically designed for duct mounting, and these utilizes a coiled sensing element, which ensures a response rate at least quadruple that of standard models. The controller is also ambient temperature compensated, ensuring efficient operation by taking into account the case and tubing surroundings.

For more versatility, the sensing element capillary tubing permits remote mounting of the sensing element. The set point can be easily read and adjusted through the controller's cover, providing an unforgettable user-friendly experience. To adjust the proportional throttling range, there is a throttling dial conveniently located inside the case.
