| VE Series - Surface Temperature Sensors |
| Description
VE Surface Temperature Sensors are temperature operated switches ideally suited for applications requiring small, precise but rugged devices. They are designed to sense surface temperatures within very narrow differentials with a high degree of reliability.
Advantages
- Miniature size
- Direct metallic heat conduction
- Rapid Response
High shock and vibration characteristics
- Field adjustable
- Hermetically sealed (optional)
Applications
- Semiconductor heat sinks
- Crystal and capacitor ovens
- Cooling system control
- Computer systems
- Motors and generators
- Alarm systems
Operations
VE Surface Temperature Sensors have a unique dual bimetal design which produces larger forces and contact motion than ordinarily found in devices of this size. Intimate coupling between the mounting base and actuating elements produces an exceptionally fast response time. Contact chatter is eliminated and the unit has no resonant points below 2000 Hz.
Military Environments
Designed for military environments for exposure to -55°C to +150°C, the VE Series Surface Sensing Thermostats meet the rugged shock and vibration requirements associated with military and high-grade industrial applications.
Typical control applications include:
- Heat sinked components
- Electronic systems
- Temperature sensitive systems
- Frequency stability
- Power supplies
- Heat dissipation systems
- Motors, generators, compressors
- Truck, railcar environmental applications

| C8 Series - Ambient Temperature Sensors |
Description
C8 Ambient Temperature Sensors are cartridge-size thermal switches ideally suited to control or monitor temperature in either air or liquid mediums.
Available in different mounting arrangements, they provide a high degree of sensitivity and operate under severe environmental conditions.
Advantages
- Fast response time
- Narrow temperature differential
- Hermetically sealed
- Stable under severe shock and vibration
Applications
- Heating and cooling equipment
- Ventilation systems
- Fire detection
- Hydraulic systems
- Critical temperature equipment
Operations
C8 Sensors are based on a differential expansion principle, comparing the expansion or contraction of the outer shell in relation to an internal member that is not affected by temperature. The differential in expansion of these two members is then multiplied by the internal mechanism and transferred as a motion to the contacts. The contacts are built in a separate fused glass header with a minimum current path to reduce self-heating effects.
Military Environments
Designed for military environments for exposure to -55°C to +150°C, the C8 Series Ambient Sensing Thermostats meet the rugged shock and vibration requirements associated with military and high-grade industrial applications. Typical control applications include:
- Heating and cooling equipment
- Ventilation systems
- Fire detection
- Hydraulic systems
- Critical temperature equipment
