Sensors 

Thermocouples

Thermocouples are best suited for high temperatures, extreme environments or applications requiring microscopic size sensors. These fiberglass insulated thermocouples are capable of temperatures up to 900°F (480°C) for continuous operation. Watlow provides grounded, ungrounded and exposed junctions on millions of manufactured thermocouples.

Resistance Temperature Sensors

RTDs are suited for applications where accuracy and stability are essential for proper control in applications below 1200°F (650C). Thermistors are best for applications where fast time response and high change in resistance over limited temperature range is desired. Maximum operating temperature on Watlow thermistors is 572°F (300°C).
