The RTTS300 is a 3-channel temperature transmitter, compatible with the obsolete TS300 models installed on many machines worldwide. This upgrade over the outdated version not only improves quality and accuracy, but also greatly reduces weight.

 Features RTTS300

  • Self calibration, it doesn’t need a calibration on the field even for the spare parts.
  • Several self tests are performed to assure the measure accuracy.
  • Rotating and stationary parts can be swapped or replaced individually.
  • Fast troubleshooting through a simple coding for each output, without disassembling the parts: 

          Fault detection                                                                                                 Reading

          PT100 short circuit                                                                                        4.600 V

          PT100 open/ broken                                                                                      4.500 V

          No communication between parts                                                                4.800 V

          Measure not reliable                                                                                      4.700 V


  • MODBUS with isolated RS485 (Optional).
  • Fully isolated output from power supply for better noise immunity.
  • Total weight of only: 1.2Kg.
  • All built-in, it doesn’t need external signal condition board.
  • Installation accepts a distance of 10 mm between the rotating and stationary device.
