Viscous Fiber Plants

Viscous Fiber Plants

Use Case: Maturing Drum Temperature Monitoring

Replacement of gauge temperature sensor
150 seconds per revolution. Each batch process takes about four hours.


  • Temperature is monitored to maintain consistency of the viscous fiber entering the drum.
  • Existing system requires manual temperature readings.
  • Wired temperature measurement is not available because the tank is rotating.


  • Wireless temperature measurement
    • GWx1, transmitter (YTA) x1 at measuring point on the maturing drum
    • Repeater x2 at fixed locations pointing in different directions (for redundancy)
  • High quality wireless communication was confirmed. The PER (packet error rate) was 0%.
  • The installation locations of the repeaters must be carefully chosen because the radio signal path changes dynamically as the transmitter rotates.
