Remote Bulb Temperature Controllers
T991A Proportional Temperature Controller
T991A proportional temperature controllers provide modulating control of water or air temperatures in ducts, tanks, and similar applications.
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
