Temperature Transmitters & Sensor Assemblies
Temperature transmitters and complete sensor assemblies convert a sensing element's output into a usable signal for process instruments, PLCs, or control systems. Assemblies may combine a thermocouple or RTD with a protection sheath, process fitting, terminal head, cable, connector, or transmitter. The correct configuration depends on the temperature range, process medium, response time, wiring distance, electrical noise, required accuracy, and controller input. A transmitter can provide a standardised output such as 4–20 mA or a supported digital protocol, depending on the selected model. Sensor placement, insertion depth, grounding, calibration, and mechanical protection are important to obtain a representative process reading. The full measurement chain should be specified together to avoid mismatched sensor and instrument inputs.
Temperature transmitter: the sensor reading is converted into a 4–20 mA signal for the control system.
How it works
The sensor responds to temperature and produces a resistance or thermoelectric signal. The transmitter, where used, conditions or converts that signal into an output suitable for the receiving control system.
