Additional Feature

OMEGA's fine diameter transition joint thermocouple probes provide durability and fast, accurate temperature measurements. Diameters as small 0.25mm (0.010") allow "pin-point" accuracy of measured values while protecting the measurement junction inside the metal sheathing and mineral insualtion of the OMEGACLAD™ cable . The metal transition barrel provides a solid mounting surface and the PFA insulated lead wire is a cost-effective solution for environmental temperatures to 260°C (500°F). For extended life, low drift operation at higher temperatures, choose Super OMEGACLAD™ XL sheathing, available in Type K and N calibrations.

Rated 5 out of 5 by from 0.01" fine wire T/C for speedy measurements We use the 0.10" fine wire t/c for testing the temperature reaction time of of thermal sensing shower valves to measure the speed of the reaction time in the milliseconds.

Rated 4 out of 5 by from nice coupler great for our application. the only problem i had was it needed to go into the side of a hot block had to bend the probe about 90' and the first one cracked.i was able to install the second one at less of an angle it was fine.

What would the transition joint diameter be for the TK36-CASS-020G-2? Could I use a thermocouple compression fitting on this? Would omegalok work for that?

Asked by: DerekJ
Thank you for your inquiry DerekJ. The transition joint diameter is 1/4". Yes you can use compression fittings with this probe.

Over what distance at the tip does this measure temperature for this model?

Asked by: NikiLab
The thermocouple junction is at the tip of the probe. Within the first 0.5 inch the temperature is being taken.

In reference guide, upper temperature limit table indicates the upper temperature limit of T-TC (24AWG, 0.020 in) is 200 C. This website shows the upper temperature limit of TJ36-CPSS-020U-6 is 260 C. Which is correct?

Asked by: Tabull
Thank you for your inquiry. TJ36-CPSS-020U-6 has MgO Insulation that allows for higher upper temperature.

I'm looking for a thermocouple with the highest accuracy possible (range of temp from 0 to 40°C) and a 0.01" probe diameter. What is the best thermocouple for this ?

Asked by: Palyb
Thank you for your inquiry. We need more information in order to provide a product. Please email your request to that way one of our engineers can advise.

Hello, is this probe able to be bent to a 90 degree configuration? If so, what bend radius would be achievable? My application has a very small space to operate in.

Asked by: Mech Engineer CB
Thank you for your inquiry. Bending Metallic Sheathed Thermocouples: The Minimum Bend RADIUS Should be NO LESS than THREE TIMES the diameter of the probe being bent.
