Rail Mount Transmitters Standard F11-40RM Series

RTD Assemblies

The F11-40RM series is a basic, non-isolated, easy-to-use two-wire transmitter. Needing no external power supply other than your LOOP power, the F11-40RM can be used for three or four wire RTDs; as well as, thermocouple calibration types B, C (W5), E, J, K, N, R, S & T.

Thermocouple input cold junction compensation (CJC) is fully automatic by means of an accurate measurement of the terminal temperature. Alternatively, the CJC can be disabled upon request. Also available are head mount enclosures with digital displays. Either regular duty or heavy duty, NEMA rated head mount displays.

  • Accepts RTD in three and four wire connection and 11 thermocouple types
  • NAMUR compliant
  • This non-isolated device should not be used with multiple grounded junction tTiermocouples when signals are input into each of their own transmitter. All signals are input into the same data acquisition system.
  • Typical span is full range of sensor, can be programmed for special ranges. Example: 100-500 degrees Fahrenheit
