ST. LOUIS – Watlow Electric Manufacturing Co. recently introduced its new patent-pending MICROCOIL technology. The technology features miniature thermocouples that can measure surface temperatures perpendicularly, with an unparalleled degree of accuracy and design flexibility.

The MICROCOIL thermocouple was designed for such demanding applications as process chambers, wafer supports, heat sinks, chip cases, platens, packaging and cleaning. The MICROCOIL's features include:

  • Miniature size – The footprint can be as small as 0.110-inch diameter, allowing for precise management in tight spaces. It features single, ungrounded junctions in mineral insulated thermocouple cable as small as 0.010-inch diameter, or dual, isolated ungrounded junctions as small as 0.032-inch diameter.
  • Electrically isolated/shielded – The MICROCOIL's thermocouple uses mineral insulated thermocouple cable, which will, along with an ungrounded junction, electrically isolate the circuit from the surface being measured. With higher voltage applications, ceramic-sensing discs can be used for additional protection.
  • 700C/1292F maximum continuous temperature – The unit can withstand extreme temperature requirements in a variety of applications.
  • Choice of materials – The MICROCOIL can use a wide range of materials depending on the application's temperature and material compatibility requirements. Metals and ceramics can be used to customize response time, accuracy, contamination and electrical isolation.
  • Self leveling/loading – The MICROCOIL thermocouple offers excellent repeatability of measurement for a variety of surfaces.

The MICROCOIL comes with available options such as: dual, isolated thermocouples in the same sensor; ungrounded or grounded, Type J or Type K calibration; RF/IR shield; and shielded lead wire with drain, either isolated from or connected to the sensor sheath.

Watlow is the world's largest custom designer and manufacturer of industrial heaters, sensors and controls. The firm's corporate headquarters are in St. Louis, Missouri with manufacturing facilities worldwide.
