DESCRIPTION


THERMOSWITCH® controllers control temperatures as

low as -100ºF (-73ºC) and as high as 600ºF (316ºC) with

the proven dependability of over 70 years of service to

satisfied customers.



PRINCIPAL OF OPERATION


The THERMOSWITCH® controller is a strut-and-tube type

thermostat comprised of two basic parts: the outer shell,

made of high-expanding metal and the strut assembly, made

of low-expanding metal.

A pair of electrical contacts is mounted on the strut assembly

and installed in the shell under tension or compression.

Since each end of the strut assembly is mechanically

connected to the ends of the shell, a net change of force

is produced on the strut assembly as the shell expands or

contracts with changing temperature. The temperature at

which the contacts “make” or “break” can be regulated by

a temperature adjusting sleeve.

This adaptation of the differential-expansion principle gives

several important control advantages:

• Fast Response

Since the outer shell of the THERMOSWITCH® is the

active sensing member, and not merely a housing, response

to temperature change is almost instantaneous.

• Close Control

The controller’s shell and strut arrangement has “anticipation”

characteristics which substantially reduce the amount of

overshoot and undershoot during conditions of rapid

temperature change. Anticipation is produced by an inherent time

lag between the shell and struts, which causes the shell

‘to “lead” the struts by an interval that varies with the rate

of temperature change. With rapid temperature rise, the shell

exerts a larger net force on the struts and tends to pull them

apart sooner than if the temperature were rising slowly.

The result is several degrees or more of anticipation which

helps produce closer control.

• Extreme Sensitivity

The strut and contact assembly operates by slow make and

break. This means that every temperature change, no matter

how small, causes a corresponding change in the space

between the electrical contacts. Therefore, contact action

can be produced by a very small temperature change,

which accounts for the THERMOSWITCH® controller’s

excellent resolution sensitivity of 0.1ºF (0.05ºC).

• Vibration Resistance

Since the strut assembly is assembled under tension or

compression, a properly installed unit has excellent vibration

resistance and will provide the best possible control under

difficult physical conditions.

• Agency Approved

Various models are listed or component recognized

by Underwriters Laboratories (UL) and certified by the

Canadian Standards Association (CSA).
