Digital controls Temperature probes Thermocouples Types J, K and T Wide temperature range to 900 C Rugged and dependable 316 stainless steel probe sheath Many sizes, fittings, leads and terminations Select thermocouples for demanding industrial and commercial applications in the higher temperature ranges to 900 degrees C. Thermocouples offer a generally faster speed of response than RTD's and are normally lower in cost. The robustness of the thermocouple makes it especially suitable for industrial use.
Thermocouples are also fast to respond and can accept long extension wire lengths.
The thermocouple is based on the principle that a measurable and predictable voltage is generated at a junction between two dissimilar metals, which is a function of temperature. Measurement of the voltage indicates process temperature. Standard thermocouples are available.
