Honeywell Proportional Temperature Controller - T991A1012/U

The Proportional Temperature Controller by Honeywell is an advanced temperature regulation device designed with a set-point temperature range from 0 to 100 degrees Fahrenheit. This device incorporates a Copper Bulb Sensor Element that is housed in a 1/2 inch diameter and 4-3/16 inch long bulb size, contributing to its precise temperature sensing abilities. Notably, the unit features a 135 ohm potentiometer for proficient coordination of operations and boasts of a 20 foot capillary tubing for flexible installation.

The Proportional Temperature Controller is engineered with Fast Response Models designed specifically for duct mounting. These models are fitted with a coiled sensing element that offers a response rate at least four times quicker than conventional models, enhancing the accuracy and speed of temperature regulation.

Significantly, the device is inherently structured to compensate for ambient temperature variations with regard to the casing and tubing, ensuring stabilized performance even under fluctuating ambient conditions. The design allows for the remote mounting of the sensing element, an added feature that enhances the controller's adaptability to different industrial settings.

The Proportional Temperature Controller allows users to read and adjust the set point through its cover, facilitating easy and efficient operation. Additionally, the unit features a throttling dial located inside the casing, enabling users to adjust the proportional throttling range, hence allowing for detailed and precise control over the temperature regulation process.
