Temperature Sensors - Thermostats - Mechanical

The LC72AY-1 is a mechanical thermostat produced by Sensata Technologies which is an American-based industrial technology leader, providing high-quality sensing solutions and control products. The LC72AY-1 thermostat is designed for applications where specific temperature range must be maintained, such as food warming cabinets and small portable appliances. It is used to sense temperatures up to 200°F (93°C) with an accuracy of ±1°F (0.5°C).

Applications

The LC72AY-1 mechanical thermostat is designed to meet the requirements of household and commercial applications that require precise temperature control ranging from 60°F (15°C) to 200°F (93°C). It is commonly used in food warming appliances such as catering buffets, baking ovens, deep-fat fryers, steam ovens, ranges, griddles, grills, and food warmers. It can also be used in space heaters, dishwashers, ice makers, walk-in coolers, and other refrigeration or heating appliances.

Working Principle

The LC72AY-1 mechanical thermostat is a temperature sensing and switching device based on liquid expansion which is caused by changes in ambient temperature. When the ambient temperature rises, the liquid inside the device expands and with the force of a spring, it pushes on a flexible diaphragm, creating an opening in the contacts to break an electrical circuit. Conversely, when the ambient temperature decreases, the liquid in the thermostat contracts and pressure on the diaphragm is released, causing the spring to push the contacts back together, creating a closed circuit. This switching action allows the device to accurately maintain the set temperature range.
