What is the definition of a Powers pneumatic thermostat? It is a type of temperature control system which uses air pressure to regulate the temperature of a space or process. It is commonly used in industrial and commercial environments to maintain a certain temperature for a certain period of time. The thermostat consists of two basic parts, an air-sensing element and an air-actuated valve. The air-sensing element senses changes in the air pressure and sends a signal to the air-actuated valve. This valve then adjusts the flow of air or steam to regulate the temperature in the space or process. The thermostat can be set to a certain temperature and will maintain that temperature until the air pressure changes, at which point it will adjust the flow of air or steam to maintain the desired temperature. By controlling the temperature of a space or process, the Powers pneumatic thermostat can help to reduce energy consumption and optimize the performance of the system. Furthermore, it
