Working Principles of temperature transmitter:
Temperature transmitters operate by converting temperature readings from a sensor element — typically an RTD (Resistance Temperature Detector) or a thermocouple — into a standardized electrical signal, usually 4–20 mA.
When the sensor detects temperature changes, it produces a corresponding electrical signal based on the variation in resistance (for RTDs) or voltage (for thermocouples). The transmitter’s internal signal conditioning circuit then amplifies, linearizes, and converts this signal into a stable current output compatible with industrial control systems such as PLCs, DCS, and SCADA.
Advanced models of temperature transmitters are equipped with HART communication protocol, allowing remote calibration, diagnostics, and real-time monitoring, which ensures higher accuracy and system efficiency.
These transmitters are ideal for process industries, refineries, power plants, and chemical applications where precise temperature measurement and control are critical for operational safety and efficiency.
