Thermostats
D1 Model
- Bulb and Capillary Type Thermostats
These temperature controls, with normally closed contacts, open on temperature rise, and are suitable for controlling the temperature of a wide variety of electrically heated liquids, solids, surfaces air and other gases. These thermostats may be used in ovens, cleaning baths, platens, pipelines and sterilizing equipment, to name only a few. The expansion and contraction of the fluid in the sensing bulb controls the temperature of these thermostats.
- Double-Pole, Single-Throw, Snap Action, Direct Acting,
