• 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.Proportional Temperature Controller, 4-3/16 inch bulb lengthAnalog Output | One 135 Ohm Potentiometer |
