Temperature Sensors - Thermostats - Mechanical are important tools for controlling temperatures in various environments, such as homes, businesses and manufacturing plants. The OHD3-90B applies the principle of thermionic emission, which is commonly used in domestic and commercial heating and cooling systems. This temperature sensing device operates by measuring the temperature of objects and surfaces in a closed system environment. The OHD3-90B provides accurate temperature readings for both indoor and outdoor applications, enabling users to control temperatures more accurately than other methods.

The OHD3-90B operates using a thermionic emission principle, which is based on the fact that certain materials, such as metal, have the ability to emit electrons when heated. When the material reaches a certain temperature, these electrons are emitted, creating a direct current in the circuit. This DC current is then detected by the OHD3-90B and used as an indication of the temperature of the surface. The OHD3-90B can then be connected to a variety of HVAC systems, allowing them to accurately control the temperature of a space based on the readings given by the OHD3-90B.

The OHD3-90B is composed of two elements, an outer housing and an internal sensing element. The sensing element is a metal cylinder with a permeable membrane that serves as a temperature sensor. The outer housing is made of an insulation material, such as a ceramic or a plastic, which keeps the internal sensing element from being affected by external sources of heat or cold. When the temperature at the membrane changes, the flow of electrons emitted by the membrane changes, creating an electric current in the circuit. This current is then used by the OHD3-90B as an indication of the current temperature.

Once installed, the OHD3-90B can be programmed to detect and respond to certain temperature thresholds. When the temperature in the environment exceeds a certain threshold, the OHD3-90B sends a signal to the connected HVAC system, activating a control valve and cooling or heating the environment. This prevents the room or area from overheating or becoming too cold. The sensitivity of the temperature threshold can be adjusted to match the desired temperature, allowing users to more accurately control the temperature of their environment.

The OHD3-90B is a reliable, accurate and cost-effective way to control indoor and outdoor temperatures in domestic and commercial settings. This device is easy to install and can be programmed to detect and respond to temperature changes. The OHD3-90B has the ability to measure and adjust temperatures quickly and accurately, allowing users to maintain comfortable temperatures in their environment. As a result, the OHD3-90B is a valuable tool for Thermal Control Engineering.
