SIEMENS SITRANS TR320 (HART, Universal) Temperature Transmitter


& Free Shipping

Siemens SITRANS TR320 transmitters offer versatile functionality suitable for diverse industries. Their compact design facilitates easy mounting on standard DIN rails, in protective boxes, or within control cabinets. These transmitters support a wide range of sensors and signal sources via their universal input module:

  • Resistance thermometer (2-wire, 3-wire, 4-wire connection)
  • Thermocouples
  • Linear resistance, potentiometer, and DC voltage sources


Equipped with a HART communication interface, the output signal is a load-independent direct current ranging from 4 to 20 mA, in line with the input characteristic and augmented by the digital HART signal.

  • Compact design
  • Galvanic isolation
  • Test terminals for ammeter
  • Diagnostics LED (green/red)
  • Input monitoring wire break and short-circuit
  • Self-monitoring
  • Configuration status stored in EEPROM
  • Expanded diagnostic functions, such as slave pointer, operating hours counter, etc.
  • Special characteristic
  • Electromagnetic compatibility according to EN 61326 and NE21
  • SIL2/3 (with order note C20)
