Temperature transmitter vS temperature sensor

A Temperature Transmitter, on the other hand, takes the signal from a temperature sensor, processes it, and converts it into a standardized output (e.g., 4-20 mA, 0-10 V, or digital signals like HART or Modbus). It integrates conditioning, amplification, and signal transmission, making it suitable for long-distance communication with control systems.

A Temperature Sensor is a device that directly measures temperature and outputs a raw signal (e.g., resistance or voltage) based on the sensed temperature. Examples include thermocouples, RTDs, and thermistors. It is a component that requires additional circuitry or devices to convert its signal into usable data.

Key Differences:

Function: Sensors measure temperature directly; transmitters process and transmit the signal.

Output: Sensors provide raw signals; transmitters offer standardized outputs.

Use Case: Sensors are used in simple systems; transmitters are ideal for industrial automation and remote monitoring.

Transmitters add signal conditioning and communication capabilities, while sensors focus solely on measurement.
