Maturing Drum Temperature Monitoring

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.

Industries

  • Chemical

    Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
