    Case Study – Industrial Sensor Heating

    Customer Background:

    A leading European industrial automation company approached us to solve temperature instability in their outdoor environmental monitoring sensors, used in oil & gas sites where temperatures drop to -40°C.

    Project Challenges:

  • Space limitation inside the sensor housing (max heater thickness 0.2mm).
  • Need for precise temperature stability within ±0.5°C in fluctuating humidity.
  • Operation in environments with high chemical exposure and possible water ingress.
  • Our Solution Provided:

    We designed a 24V Kapton heater with AWG22 silicone-insulated leads, ±3% resistance tolerance, and 1.5 W/cm² power density. The heater was given an IP67 waterproof rating and a semi-transparent film for easy inspection.

    Customer Satisfaction:

    After 6 months of continuous operation, the client reported a 40% improvement in sensor reliability and zero failure rate in extreme cold. They have since expanded orders to include heaters for other equipment models.
