Honeywell Proportional Temperature Controller - T991A1103/U

The Proportional Temperature Controller by Honeywell is a robust and efficient solution for controlling set point temperatures ranging from -15°C to 35°C. This controller features a copper bulb sensor element, designed with a 1/2 inch diameter and a length of 4-3/16 inches. The unit is also equipped with a 135-ohm potentiometer and a capillary of 20 feet in length.

This temperature controller is additionally distinguished by its fast response models that are suitable for duct mounting. The sensing element within these models is coiled, which ensures a response rate that is at least four times faster than the standard models. The ambient temperature is compensated within the unit's case and tubing for precision and reliability.

The design allows for the remote mounting of the sensing element, thanks to the sensing element capillary tubing. Additionally, the set point can be easily read and adjusted through the cover of the controller, promoting ease of use and operational efficiency. Furthermore, the proportional temperature controller features a throttling dial inside the case, which can be adjusted to optimize the proportional throttling range. This robust feature set makes the Honeywell Proportional Temperature Controller a practical choice for precise, reliable, and efficient temperature control.
