Temperature Monitoring in a Dryer

Application

Temperature monitoring in a dryer

• Temperature monitoring at various drying stages
• Distance from the first measurement point to the control room is approx. 130 meters.
• Switchover of existing temperature monitoring system from off-line to on-line.

Challenges

• Manual temperature reading requires walking about 130 m and climbing up and down elevated sections of the dryer stages.
• Multiple temperature measurement points along the various stages of the dryer require many cables to the control room.
• Very high humidity.

Solutions

• Wireless temperature measurement
  Gateway x1, Transmitter (YTA) x2 at measuring points near the dryer entry point, repeater x2 (for redundancy).
• High quality wireless communication was confirmed.
  The PER (packet error rate) was 0%.

Benefits

• Reduced maintenance costs.
• Robust communication with lower packet error rates.
