Temperature based volume expansion of the charge, results in a displacement of the bellow. This can be used as a constant control or as switching function in connection with electronic or electro-mechanical components. In many cases it is used as a direct mechanical actuator.
- Charge: fluid, wax, gas, adsorption charge, mixed phases, refrigerant
- Expansion from 0.05 up to 0.6 mm/K
- Applicable for temperatures from -35°C up to +380°C
- Linear characteristic
- Low hysteresis
- Pressure or displacement limitation (only gas, refrigerant and mixed phases charges)
Copper, bronze (only bellow), brass or stainless steel, various layers on request.
