RT351 Rotary Temperature Transmitter (852-011)

RT351 Rotary Temperature Transmitter (852-011)

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 4-20 mA 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 liable element in the temperature feedback loop.

1. Remove existing transmitter system from motor.

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

3. Orient RT351 rotor so that slot in shaft will align with pin in sleeve and then slide on to shaft (metal insert through stator) until it stops.

4. Verify rotor-stator spacing (5mm nominal) as shown.

5. Secure ring terminals from RTD sensor to rotor screw terminals and tighten securely.

6. Complete motor assembly.

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

Wiring Code

Frequency and Speed O utput (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.
