Self-generating wireless temperature sensors for incoming panels

Product Development Background

1.Current Status
  • Overheating is the most common cause of failure in incoming panels and bus ducts.
  • To diagnose internal conditions, the conventional temperature monitoring process involves:
    measuring the temperature using a temperature sensor → transmitting the signal through an optical or coaxial cable → displaying the temperature on a digital indicator on the front of the instrument panel
2. Drawbacks
  • It takes a long time to wire the signal line, reducing productivity; in the event of a system failure, the entire signal line must be replaced.
  • Separate power sources (batteries, DC 5V, etc.) are necessary for the operation of individual temperature sensors and transmission modules.

  • Batteries need to be replaced every 1.5 years; battery replacements cannot be performed when the lines are live due to safety concerns.
    When using DC 5V power, each transmitter requires an independent power source; the long amount of time required for wiring reduces production efficiency.
