Temperature Sensors - Thermostats - Mechanical

Temperature sensors are instruments used to measure and record temperature. These devices are widely used in the industrial field for a variety of purposes such as controlling temperatures in furnaces and ovens, monitoring climate control, monitoring safety systems, and measuring temperature and humidity in food and beverage processes. Thermostats are one type of temperature sensor, but are commonly classified as mechanical temperature sensors due to their use of physical components to detect and control temperature.A mechanical thermostat has two main components: a sensing element, such as a bimetallic or a thermal cut-off switch, and a control element, such as a gas pilot or a relay switch. The sensing element is responsible for detecting the temperature of the environment and transmitting the signal to the control element. The control element then adjusts the temperature according to the signal received from the sensing element.The bimetallic strip is the most common type of temperature sensing element. It consists of two strips of different metals bonded together. When temperature changes, the two strips expand or contract at different rates resulting in a bending of the strip. This bending then triggers a switch and sends a signal to the control element, which adjusts the temperature as needed.Thermal cut-off switches are another type of sensing element, used in combination with bimetallics to provide precise and reliable sensing of temperature. Thermal cut-off switches are designed to automatically shut off power to the device or system it is monitoring when the temperature reaches a certain level. This ensures that temperatures never reach unsafe levels and helps prevent further damage.The control element is usually a mechanical system consisting of switches, springs, and solenoids. Each type of control element operates slightly differently, but they all work by responding to the signal received from the sensing element and then triggering the appropriate switch or adjusting the appropriate spring to achieve the desired temperature. For example, a gas pilot is a control element that is triggered by a mechanical switch from the sensing element. It then opens a valve to release the appropriate amount of gas pressure, thus controlling the temperature of the system.Thermostats are an important component in many climate control and temperature monitoring systems. The combination of the temperature sensing element and the temperature control system allows thermostats to deliver a dependable and effective operation. With a wide range of sensing elements and control elements available, mechanical thermostats can be tailored to any application.
