Snap-Action Radiant Control

The 10RS line of controls from Therm-O-Disc offers reliable sensing of radiant energy in hot surface ignition applications.

The unique snap-action bimetal design not only provides high-speed contact separation and time-proven reliability, but also enables the 10RS to maintain radiant senstivity while compensating for ambient temperature changes.

A glass window is used to maximize the effect of radiant energy on the bimetal element without exposing the entire sensoring package to high ignitor temperatures.

Features and Benefits:

Glass window design maximizes effect of radiant energy without sensor overheating.
Unique U shaped actuator compensates for ambient temperature conditions.
High-speed contact switching for exceptional life characteristics.

Switch Action

The 10 RS is an automatic reset single-pole, single-throw (SPST) switch that opens its electrical contacts when exposed to heat generated by radiant energy. This is accomplished with a U shaped bimetal actuator which has one leg exposed to radiant energy while the other leg is shielded.

As radiant energy passing through the glass window heats the exposed bimetal leg, a temperature differential is created which causes the bimetal element to snap and open the contacts. As radiant energy dissipates, both actuator legs return to approximately the same temperature, allowing contacts to automatically reclose.
