OHD5R-65B Datasheet/PDFOHD5R-65B Application Field and Working Principle
OHD5R-65B temperature controllers are a modern type of temperature-sensing device used to accurately measure and control temperatures in various industrial processes. Suitable for both air-conditioning and process control, the OHD5R-65B is a typical sensor-actuator arrangement comprising a temperature sensor, a comparison and control unit, and a controller in a single package. The OHD5R-65B is used in a variety of applications requiring precise control of temperature and humidity.
Application Fields
The OHD5R-65B is primarily designed for accurate temperature control in air-conditioning systems, such as climate control systems, broadcasting studios, electrical power and construction sites. It can also be used to control temperatures in furnaces, hot water systems, medical and food processing plants, and other similar industries requiring temperature control.
Principle of Operation
The OHD5R-65B is an electro-mechanical, self-contained unit, and its temperature control principle is based on the use of two sensors. The first sensor is mounted in the hot environment and measures the ambient temperature. The second sensor is mounted in the cooler environment and measures the difference between the two temperatures. The two sensors allow the OHD5R-65B to compare the two temperatures and activate a controller to maintain the desired temperature.
The OHD5R-65B is a single-phase, self-contained control system, meaning it requires only one power supply. The controller is powered by two wires, which are connected to the power supply and the control unit. The control unit is responsible for comparing the ambient and desired temperatures, and then activating the controller when the temperatures are not within the desired range. The controller, in turn, activates the actuator, which is usually a motor control, to achieve the desired temperature.
Conclusion
The OHD5R-65B has become the go-to device for temperature control applications. With its accuracy and reliability, it is the ideal choice for a variety of temperature-sensitive applications. The OHD5R-65B is a self-contained system and requires minimal maintenance, making it an efficient and cost-effective solution.
