The RTTDNS is a DIENES-compatible temperature transmitter with frequency output, capable of reading temperature and speed.

 Features RTTDNS

  • Compatible with the DIENES model.
  • 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 .
  • Quick troubleshooting through a simple coding for each output, without disassembling the parts:

          Fault detection                                                                                                 Reading

          PT100 short circuit                                                                                         1136 Hz

          PT100 open/ broken                                                                                       1186 Hz

          No communication between parts                                                                  1032 Hz

          Measure not reliable                                                                                       1084 Hz


  • Frequency output
  • Speed detector, 2 pulses for revolution
