Overview

Proportional (135 ohm) remote bulb controllers for modulating control of water or air temperature in ducts, tanks and similar applications.

Features

  • 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.
