Modulating temperature controller, 160 to 260°F, 20ft copper element, maximum operating temperature 280°F.
T991A proportional temperature controllers provide modulating control of water or air temperatures in ducts, tanks, and similar applications. Standard models have a sensing bulb and capillary; fast-response models have a coiled sensing element that operates at least four times faster than standard controllers, depending upon operating conditions.
Features & Benefits:
- Compensates for effects of ambient temperature on the case and tubing
- Sensing element capillary tubing allows remote mounting of sensing element
- Setpoint may be read and adjusted through cover
- Throttling dial inside case adjusts proportioning range
