Supported Applications
The Omega JMTSS series comprises Transition Junction Style Probes with High Temperature Molded Construction designed for temperature measurement. These probes feature a molded transition junction rated to 260°C (500°F) and are available in standard inch dimensions or metric millimeter configurations.
Operating Conditions & Performance
The series meets or exceeds Special Limits of Error (SLE) and EN 60584-2: Tolerance Class 1. The molded transition junction is rated to 260°C (500°F). Standard electrical connections include 40" PTFE-Coated Lead Wires.
Dimensions
- Diameter: 0.040" to 0.125" (Standard) or 1.0 mm to 3.0 mm (Metric)
- Overall Length: 6" or 12" (Standard) or 150 mm or 300 mm (Metric); other lengths available upon consultation with the Sales Department.
Configuration Options
The JMTSS series supports a broad configuration envelope across thermocouple types, sheath materials, junction styles, and dimensional standards. The housing utilizes environmentally friendly cadmium-free liquid crystal polymer.
Sensor Types & Alloys
- Type E (CHROMEGA-Constantan)
- Type J (Iron-Constantan)
- Type K (CHROMEGA®-ALOMEGA®)
- Type N (Available in Inconel N or High Performance XL material)
- Type T (Copper-Constantan)
Sheath Materials
- 304SS (Standard stainless steel)
- 316SS (Order by changing "SS" in model number to "316SS")
- Inconel® (Order by changing "SS" in model number to "IN")
- Super OMEGACLAD® XL Sheath (Available for Type N, Inconel N, or K High Performance; order by changing "SS" to "XL")
Junction Types & Ordering Qualifiers
Select the junction type using the following suffixes in the model number:
- E: Exposed
- G: Grounded
- U: Ungrounded
Key Product Differences
Variants differ by thermocouple type, sheath diameter, insertion length, and material composition. The model number guide follows the format JMTSS-- - . For example, KMTSS-125U-6 denotes a subminiature transition joint probe, Type K, 0.125" O.D. 304 stainless steel sheath, 6" length, ungrounded junction.
Metric variants follow the format KMTSS-M150G-150, indicating a subminiature transition joint probe, Type K, 1.5 mm O.D. stainless steel sheath, 150 mm length, grounded junction. The series also offers Super OMEGACLAD® XL Thermocouple Wire availability.
OMEGACAL Factory CAL is available as an option.

Just as expected
I bought these thermocouples to replace identical ones that have been damaged over the years. They are just what I needed.

I have a few JMTSS-062G-12 thermocouples that I have to install on the bulkhead of a pressurized tank. We're using screw in bulkhead connectors with thermocouple sized ferule connectors.
Hi Segan,
Thank you for the inquiry. Please email us to review options and limitations of bulkhead and compression fittings for this probe;

Does this item come with a longer wire than 3'?
Thank you for your inquiry Debbie. The Thermocouple Probes with Lead Wire & Molded Mini Transition come with a standard 40" (3.33') cable length.

I need to use a thermocouple in the ground to measure the soil temperature. Looking for a range of 40 degrees F to 185 degrees F. Need to figure out how to use a data logger with thermocouple also.
Please contact the Temperature Engineering group at temperature@omega.com for guidance on the Probes and and Data Loggers suitable for your application.

Can these be supplied with mini connector installed by factory? What is the suffix to do so?
Hi Greg,
These can be ordered with a mini male connector by adding a -SMPW-M to the part number. However, this will make that series a customized part so to get that connector added you would have to contact Technical Sales via e-mail at temp@omega.com and have them start the process to create the quote to have that part number added to the website. That process takes about a week to complete before a quote can be submitted. If you can live with a metal transition barrel it would be easier to use the TJ36 series of Rugged Heavy Duty thermocouples. With this series the Configure Now button will allow you to build the part with the -SMPW-M connector already attached.
