Heating Equipment
The main structure of Resistance temperature detection Transmitter includes interface compatibility, measurement circuit, digital/analog conversion, communication interface, shell material, etc. Resistance temperature sensing transmitters usually have interfaces that are compatible with various types of temperature sensors, such as platinum resistance temperature sensors (RTDs), thermocouples, etc. It is equipped with a dedicated measurement circuit inside for reading sensor signals and performing signal processing. These circuits usually include amplifiers, filters, compensation circuits, etc. to ensure the stability and accuracy of the measurement signal. Resistance temperature sensing transmitters are usually equipped with a digital or analog converter to convert the analog signal generated by the sensor into a digital signal for digitization or communication with a digital control system. In order to communicate with external control systems or monitoring systems, resistance temperature sensing transmitters usually have a standard communication interface. The casing is usually made of metal or engineering plastics and has good corrosion resistance and anti-interference ability to protect the internal circuit from the external environment.
