Honeywell Proportional Temperature Controller - T991A1004/U

Featuring a set-point temperature range of 0°F to 100°F, the Honeywell Proportional Temperature Controller is equipped with a copper bulb sensor element designed for precise readings. It offers a compact bulb size of a 1/2-inch in diameter and 4-3/16 inches in length, accompanied by a single 135 ohm potentiometer for precise measurement. This unit includes a 5-foot capillary for remote mounting of the sensing element.

An attribute that sets this Temperature Controller apart is its fast response model suitable for duct mounting. The uniquely designed coiled sensing element ensures a response time at least four times faster than standard models while also compensating for ambient temperature within the case and tubing.

For greater convenience, the set-point may be read and adjusted through the cover of the unit. In addition, a proportionally adjustable throttling range is maintained via the throttling dial inside the case. This high-precision feature allows the Proportional Temperature Controller to adapt to a wide range of industrial automation and control system requirements.
