Description:
The charge's volume expansion due to temperature results in a bellow's deflection. In connection with electronic or electro-mechanic components, this change in displacement may be used as constant control function or switch function. The element is often applied as a direct, mechanic actuator.
Features:

• charge: fluid, wax, gas adsorption charge, mixing phases, refrigerants
• expansions from 0.01 up to 0.35 mm/K
• suitable for temperature ranges from -35°C up to +380°C
• linear characteristic curve
• low hysteresis
• pressure or displacement limitation (only gas, refrigerant and mixing phases charge)

Material:
copper, bronze (only bellow), brass or stainless steel, various coatings on request.
Examples for application:
facility management, fittings manufacture, A/C, solar plants, food and beverage industry, radiator thermostats (fixed head, remote bulb, remote and central adjustment devices), gas switches, outlet safety devices, industrial water mixers, hot water apparatuses.
