Maturing Drum Temperature Monitoring

Application

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

• Gateway x1, 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.

Benefits

• On-line temperature measurement.
• Stable measurement of rotating tank.
• Robust communication with lower packet error rates.
