Bimetal
switches are based on a two-layer alloy leaf, which deflects
with changes in temperature. The heat producing the thermal
action works through the bimetal leaf mounting in the top
of the probe, and enables CPI to design relatively short probe
switches with a high degree of accuracy. They can be used
as temperature controllers, safety cutoffs for equipment protection,
and indicators of overheat conditions. These thermal switches
are capable of tight set point tolerances and small differential
(0-5ºF).

Factory calibrated: CPI bimetal thermal switches are factory calibrated at any temperature (within the set point range of the product series). They can operate in ambient temperatures from –65F to 700F and show excellent resistance to momentary overshoots.
Immune to problem environments: Hermetically sealed (L-1 and L-2 Series are environmentally sealed) for total protection against the effects of moisture, sand and dirt, these bimetal thermal switches are also designed to withstand severe shock and vibration with no shift in calibration.
Applications: Set point drift is not a problem with these devices, enabling them to perform reliably in demanding aircraft applications such as: environmental control systems, hydraulic systems, helicopter gearboxes, generators and bearings. Industrial equipment applications include: sterilization equipment, plastic extruders, medical equipment, heavy duty air conditioning units, gear boxes, truck drive trains, and vehicle coolant temperature control. |
