Honeywell Proportional Temperature Controller - T991A1061/U

The Proportional Temperature Controller by Honeywell boasts a set-point temperature range of 160 to 260 degrees Fahrenheit, using a copper bulb sensor element to achieve optimal precision. The sensor element is housed within a 1/2 inch diameter by 4-3/16 inch long bulb. The device also features a 135-ohm potentiometer, accompanied by a 5 ft. capillary tube.

One of the key features of this model is its speed of response when mounted within a duct. The implementation of a coiled sensing element ensures this model responds at least four times faster than standard models. In addition, temperature compensation is provided for both the case and tubing, ensuring accurate readings in diverse ambient temperatures.

This controller also offers the benefit of flexible installation, thanks to its sensing element capillary tubing. This allows for remote mounting of the sensing element, broadening the potential use cases for the controller. A standout feature is the ability to read and adjust the set point through the controller's cover, delivering both ease of use and quick temperature adjustments.

Moreover, this device is equipped with a throttling dial discretely housed within the controller case. This dial adjusts the proportional throttling range, fine-tuning temperature control to suit the specific needs of your application. Overall, Honeywell's Proportional Temperature Controller delivers rapid, precise, and versatile temperature management capabilities.
