Honeywell Proportional Temperature Controller - T991A1095/U

The Honeywell Proportional Temperature Controller offers a set point temperature range from a cold -15 degrees Celsius to a mild 35 degrees Celsius. Enacting control through the use of a copper bulb sensor element, the controller ensures accurate temperature readings with its half-inch diameter and a length of 4-3/16 inches. The controller is equipped with a 135-ohm potentiometer and a capillary of 5 ft in length. High-grade models designed for duct mounting boast a coiled sensing element, providing at least 4 times faster response rate than standard versions. The Temperature controller adjusts for ambient temperature within the case and tubing, ensuring accurate and consistent temperature control. The capillary tubing within the sensing element allows for remote mounting, further enhancing the utility and flexibility of the device. User convenience is considered with the ability to read and adjust the set point through the controller's cover. The device boasts an interior throttling dial, which allows users to adjust the proportional throttling range, ensuring efficient and precise temperature control.
