Description
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
- Compensates for effects of ambient temperature on the case and tubing
- Sensing element capillary tubing allows remote mounting of sensing element
