TempTrak® RT350 Specifications

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 reliable element in the temperature feedback loop.

TYPICAL OUTPUT CONNECTIONS



Frequency and Speed (Dienes)

Terminal 1: Supply voltage (+12VDC nominal)
Terminal 2: Supply voltage low (Common)
Terminal 3: Speed output

Current Output (4-20 mA)

Terminal 4: Supply voltage (+15VDC nominal)
Terminal 5: Current output high (+I)
Terminal 2: Current output low (-I)

Both frequency and current output signals can be used individually or simultaneously but each must be powered accordingly.
