Honeywell Proportional Temperature Controller - T991A1079/U

The Honeywell Proportional Temperature Controller is a robust device designed with a set point temperature range of 160 F to 260 F, ensuring versatile adaptability. It incorporates a copper bulb sensor element, demonstrating distinctive material excellence. The bulb size measures half an inch in diameter and 4-3/16 inches in length, guaranteeing optimal space utilization. The controller is equipped with a 135-ohm potentiometer and offers an extensive capillary length of 20 feet.

Various models of this controller are designed for fast response, making them suitable for duct mounting. These models incorporate a coiled sensing element that provides a response time at least four times faster than that of standard models. The controller compensates for ambient temperature in both the casing and the tubing, enhancing performance under varying environmental conditions. The device leverages capillary tubing for the sensing element, facilitating its remote installation.

Enhancing its usability, the controller’s set point can be read and adjusted directly from the cover. It also features a built-in throttling dial inside the case for adjusting the proportional throttling range. This efficient design ensures precise and streamlined temperature control in industrial settings. The Honeywell Proportional Temperature Controller is a testament to precise engineering and advanced technological solutions.
