RT351 Rotary Temperature Transmitter (852-013)

RT351 Rotary Temperature Transmitter (852-013)

The RT351 is a single-channel temperature measurement system designed to monitor temperature on heated godet roll shells. The system features Dienes-compatible output signals for temperature and speed as well as a linear 4-20mA output for use with standard process controllers. Error detection modes protect the heater from damage and expedite troubleshooting in the event of a sensor or other failure. Digital circuitry from sensor input to signal output and generous clearance between the rotating and stationary components make the RT351 a robust and reliable element in the temperature feedback loop.



































1. Remove RT351 transmitter from rotor base.

2. Slide the RT351 rotor base on shaft until it stops and secure with provided set screws.*

3. Attach ring lugs from the RTD sensor to RT351 transmitter terminals and tighten securely.

4. Attach RT351 transmitter onto rotor base.

5. Mount stationary can assembly to motor with hardware provided.

6. Refer to the Wiring Code and diagram above for connecting the heater control system to the RT351 signal output terminals.

* Use Loctite Threadlocker 222MS or equivalent for steps 2 and 4.

Wiring Code

Frequency and Speed Output (Dienes)

Terminal 1: Supply voltage (+Vf) (+12VDC nominal) (red typical)

Terminal 2: Supply Voltage low (Common) (blue typical)

Terminal 3: Speed output (white typical)


Standard Current Output (4 - 20 mA)

Terminal 2: Current output low (-I)

Terminal 4 : Supply voltage (+Vi) (+15VDC nominal)

Terminal 5: Current output high (+I)

Note that both the frequency and the current output signals can be used individually or simultaneously but each must be powered accordingly.
