Additional Feature

Super OMEGACLAD™ XL Probes are an excellent choice for high temperature measurement. They provide very low drift at high temperatures compared to conventional Inconel and Stainless Steel sheathed probes. XL probes are available in both K and N thermocouple calibrations. XL Probes are available in a variety of styles and lengths for Industrial Heating applications.

Rated 5 out of 5 by from Perfect thermocouple for my application I needed a thermocouple to use with an electronic controller I designed for a ceramic kiln. This thermocouple met my specs and is working perfectly. I also appreciate its mechanically robust construction.

Rated 5 out of 5 by from 1000 hours tough! We've been using these Omegaclad XL TCs for years and as long as the transition junction and lead wires are kept out of the extreme heat, they last for thousands of hours at 1000C.

Is the part number TJ36-CAXL-116U-1.0 ROHS compliant?

Asked by: Cindy W
Thank you for your inquiry. This item is not RoHS compliant.

Does the Super Omegaclad XL sheath have copper in it? I need a highly corrosion resistant sheath without copper (like Inconel 625), since copper will promote coking in my application.

Asked by: Anonymous
Hi Anonymous Thank you for the inquiry. The outer sheath of the XL version probes is Inconel 600 alloy. The inner sheath has a proprietary treatment to provide better high temperature performance. Best regards OMEGA

What sort of pressure ranges can TJ36-CAXL-116E-18 operate in? What would be the maximum pressure it can be safely subjected to?

Asked by: GradStudent
The probe referred to has an exposed junction so it would only be good for standard atmospheric pressure. If a grounded or ungrounded junction is selected then they could be exposed to pressurized environments though Omega does not place a specification on it.
