proportional temperature controllers
T991
For modulating control of water or air temperature in ducts, tanks and similar applications.
•Fast response models (for duct mounting) have coiled sensing
element giving at least four times faster response than standard models.
•Ambient temperature compensated for 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 proportional throttling range.
