RT351 Rotary Temperature Transmitter (852-001)

RT351 Rotary Temperature Transmitter (852-001)

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 the existing transmitter system from the motor.

2. Insert the sheathed RTD leads from the RT351 rotor into the motor shaft until they exit the shaft at the front of the godet.

3. Place the rotor with mounting collar over the end of the shaft until it stops against the shaft then tighten the collar screws to secure the rotor.

4. Connect the ring terminals from the rotor to the RTD terminals at the front of the godet.

5. Install the RT351 stator bolt through the fan plate. Orient the stator for convenient routing of the output signal cables then secure the stator with the lock - washer and nut provided.

6. After reinstalling the fan plate on the motor, verify the rotor-stator spacing (5mm nominal) as shown.

7. Refer to the Wiring Code below for connecting the RT351 output signal cables to the heater control system.

Wiring Code

Two cables exit the RT351 stationary unit each containing three wires:

Cable 1: Standard Current Output (4 – 20 mA)

Yellow – Supply voltage (+Vi) (+15VDC nominal)

Gray – Current output high (+I)

Blue – Current output low (-I); Also Supply Voltage low (Common)

Cable 2: Frequency and Speed Output (Dienes)

Red – Supply voltage (+Vf) (+12VDC nominal)

White – Speed output

Blue – Common

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