Electromechanical Thermoswitch® temperature controllers are said to provide accurate, reliable operation in demanding industrial and commercial applications. The controllers reportedly require no external power source, respond quickly to temperature changes, and cost 50 percent less than an equivalent electronic control. Applications range from commercial appliances to industrial services such as packaging equipment, industrial laminators, and medical vaporizers. Available in probe or surface-mount configurations, the controllers use the differential expansion of metals to control internal electrical contacts and regulate temperature. Explosion-proof enclosures are available for hazardous locations protection, and vibration resistance provides control advantages under difficult physical conditions. The company says its controllers are installed in direct contact with the heated surface so that any temperature change is sensed virtually instantly. Fenwal Controls
