Temperature control devices and temperature transmitter products

Temperature controllers and temperature transmitters are used to read measurements from thermocouples or PT100/RTD sensors and transmit them to control/monitoring systems. The correct product selection depends on the sensor type, signal output, and mounting/environmental conditions. This page summarizes the basic selection criteria and the necessary information for a quick quote. Which Product Does What? Temperature Transmitter: To convert the sensor signal to a standard output (e.g., 4–20 mA) and transmit it to systems such as PLC/SCADA. Temperature Controller: To read the measurement and control equipment such as heaters/coolers according to the set value. Indicators / Panel Type Units: For monitoring temperature in the field. Selection Guide (Quick) Input type: Thermocouple (K/J/T/S etc.) or PT100/RTD? Output requirement: 4–20 mA, 0–10 V, relay, communication (if any). Mounting: Panel mounting, field mounting, DIN rail, etc. Environment: Temperature, humidity, vibration, field conditions. Control requirement: Measurement only, or PID control? Compatibility Note The sensor type and device input must be compatible. If you are unsure, please share the sensor type you are using (e.g., K-type / PT100 3-wire) and application details; we can help you make the right choice.
