Digi-Sense Thermowell Brass, 4" Length, 3/4" Connection

To match your probe to a thermowell, first measure the distance from the probe's tip to the top of the thread (typical thread length is 0.5" for 1/2" NPT fittings). Next, match this length to the probe depth of the thermowell ("A" dimension). Other thermowell sizes and materials are available-call our Application Specialists for more information. Limited-Space Thermowell when you need a shorter insertion depth. Standard Thermowell for general-purpose applications. Heavy-Duty Thermowell for higher fluid velocity ratings. Designed for easy replacement of your industrial probe without shutting the operation down.
