Temperature sensors, wires and cables

Offering temperature sensors products to fit customer needs. A wide variety of temperature sensors including thermocouples, resistance temperature detectors (RTDs) and thermistors as well as wire, mineral insulated cable, connectors and hardware are supplied by and manufactured at Watlow’s fully integrated facility.

For more complex needs, extended capability products that go beyond traditional functionality are available for large quantity orders. Please contact Watlow for specific application requirements and discuss which products may best fit the application.

Temperature sensor accuracy, repeatability and stability are critical for wafer processing applications. Our advanced sensor technologies around fiber optics, thermocouples and RTDs and thermistor sensor assemblies are specially designed to ensure precise and repeatable temperature feedback in challenging environments. Watlow’s fiber optic sensor offers superior accuracy in RF plasma conditions and reduces the required footprint by integrating the signal conditioner into the temperature control module.
