SUCH smart temperature transmitter (HART 4-20mA) is designed for high-accuracy temperature measurement with support for RTD and thermocouple input signals. It operates within a wide 12-40 VDC power supply range, ensuring flexibility for various industrial applications. With an accuracy of ≤0.1% FS, it delivers precise and reliable readings. The transmitter also features built-in cold junction compensation, making it ideal for thermocouple-based systems. Additionally, HART communication allows for easy configuration and integration into advanced control systems, offering both performance and versatility.
Note: This transmitter is compatible with lead-type temperature sensors, armored temperature sensors, temperature controllers, and temperature recorders.
A temperature transmitter is an electronic device that converts the output signal from a temperature sensor (such as a thermocouple or RTD) into a standardized output signal, typically 4-20mA or 0-10V. Its primary function is to enable temperature data to be transmitted over long distances to control systems or monitoring equipment, facilitating temperature automation and control. Temperature transmitters ensure that temperature readings are reliably communicated to control systems for automated monitoring and adjustments.
A temperature transmitter works by receiving the signal from a temperature sensor, such as a thermocouple or RTD, which produces a voltage or resistance change in response to temperature changes. The transmitter then converts this signal into a standardized current or voltage output, such as 4-20mA, which is commonly used in industrial applications for remote signal transmission. This conversion allows the temperature data to be integrated into control systems, enabling accurate temperature monitoring and control in automation processes.
Temperature transmitters are compatible with various types of temperature sensors, including thermocouples, RTDs (resistance temperature detectors), and thermistors. Thermocouples are used in a wide temperature range and respond quickly, while RTDs provide high accuracy and stability, making them ideal for precise temperature measurements. Thermistors are used for measuring smaller temperature ranges. The choice of sensor depends on the specific temperature measurement requirements of the application.
