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
Challenges
— 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.
Solutions
— Wireless temperature measurement
— 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.
ISA100 Wireless Benefits
— on-line temperature measurement.
— Stable measurement of rotating tank.
— Robust communication with lower packet error rates.
