RT351 Rotary Temperature Transmitter (852-016)

RT351 Rotary Temperature Transmitter (852-016)

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 existing transmitter system from motor.

2. Attach RT351 stator to motor housing using st andoffs and bolts provided. (Orient stator for convenient routing of output signal cables.)

3. Slide RT351 rotor onto shaft (metal insert through stator) until it stops.

4. Verify rotor-stator spacing (5mm nominal) as shown and tighten set screws on sleeve to shaft.

5. Secure ring terminals from RTD sensor to rotor screw terminals.

6. Complete motor assembly.

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

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 (4-20mA)

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.
