The TH-22 Series thermistor probes are constructed with the 55000 Series glass encapsulated thermistor elements which provide excellent stability and accuracy. The connector design includes an LCP insert with nickel plated copper pins for high temperature applications, 200°C (392°F). With a maximum continuous temperature rating of -80 to 200°C (-112 to 392°F), and intermittent operation to 250°C (482°F), these thermistor sensors can be used in applications previously out of reach of epoxy coated thermistor sensors. The probes can be ordered in any length but we highly recommend a minimum immersion depth of 1.5". Short probes run the risk of error due to stem conduction effects.

Hi, I'm wondering how to determine the length of the probe and what needs to be considered in terms of deciding it? How to include the resistance of the probe (lead) into temperature calculation? Thanks!
Hi Gang Ren,
Thank you for the inquiry. In general 3 inches is minimum immersion length. This can vary depending on the media and the process flow. Fast moving liquids or gas allow for shorter lengths. Lead wire length can be ignored most often because lead length resistance is usually less then 5 Ohms, and thermistor resistance is in the range of 2000 to 10,000 Ohms. Please contact us for assistance in review of your application.
