Supported Applications
The Omega TJ36 series consists of rugged thermocouple transition joint probes designed for temperature measurement in harsh conditions. These sensors feature a compact mineral-insulated cable construction with braided fiberglass insulation on the lead wire, providing durability and thermal protection.
Applications include environments requiring operation up to 482°C (900°F), enabled by the use of fiberglass and ceramic insulation materials within the probe assembly.
Operating Conditions & Performance
The series supports a measurement range from 260 °C (500 °F) to 1204 °C (2200 °F), with specific upper temperature guidelines varying by sheath material and diameter. The probes meet or exceed Special Limits of Error (SLE) and EN 60584-2 Tolerance Class 1 accuracy standards.
- Process Temperature: Up to 482°C (900°F)
- Accuracy: SLE (Special Limits of Error) and EN 60584-2 Tolerance Class 1
- Sheath Diameters: 1.59 mm (1/16 in), 3.18 mm (1/8 in), 4.78 mm (3/16 in), and 6.35 mm (1/4 in)
- Stem Length: Standard stem length is 152.4 mm (6 in) with a 38 mm (1.50 in) spring strain relief
The transition joint measures 27 mm (1.06 in). Overall probe lengths are available at 150 mm (6"), 300 mm (12"), and 450 mm (18"). The design incorporates a spring strain relief to prevent wire pinching.
Temperature Guidelines by Sheath Material
The maximum operating temperature varies based on the selected sheath material and diameter, as documented in the series specification table:
- Type K (CHROMEGA®/ALOMEGA®) with 304 SS: Up to 899 °C (1650 °F)
- Type K with Inconel® 600: Ranges from 921 °C (1690 °F) for 1.59 mm diameter up to 1149 °C (2100 °F) for larger diameters
- Type K with Super OMEGACLAD® XL: Ranges from 1038 °C (1900 °F) up to 1204 °C (2200 °F)
- Type J (IRON-CONSTANTAN) with 304 SS: Up to 721 °C (1330 °F)
- Type T (COPPER-CONSTANTAN) with 304 SS: Up to 371 °C (700 °F)
Configuration Options
The TJ36 series is configurable across multiple parameters including thermocouple type, sheath material, junction configuration, and lead termination. The standard electrical connection features stripped lead terminations.
- Thermocouple Types: Type K (CHROMEGA®/ALOMEGA®), Type J (IRON-CONSTANTAN), Type T (COPPER-CONSTANTAN)
- Junction Configurations: Grounded, Exposed, or Ungrounded
- Sheath Materials: 304 SS, Inconel® 600, and Super OMEGACLAD® XL are standard. Additional sheaths available include 310 SS, 316 SS, 321 SS, Hastelloy® X.
- Connector Options: Optional M8/M12 connectors (male straight or right-angled) can be added to the model number for additional cost using suffixes "M8-S-M", "M12-S-M", "M8-R-M", or "M12-R-M".
- Dual Element: Dual element configurations are available in specific variants (e.g., -DUAL).
The series is manufactured in the USA. The model number guide follows the format: TJ36-----CC.
Key Product Differences
Variants within the series differ primarily by thermocouple type, sheath material composition, and physical dimensions. The model number explicitly defines these distinctions:
- Sheath Material Codes: CASS (304 SS), CAIN (Inconel® 600), CAXL (Super OMEGACLAD® XL)
- Diameter Codes: 116 (1/16"), 18 (1/8"), 316 (3/16"), 14 (1/4")
- Junction Type Indicators: G for Grounded, E for Exposed, U for Ungrounded
The series offers standard stripped lead terminations as the default configuration. Variants with M8 or M12 connectors are distinguished by specific suffixes added to the base model number.

My top choice for temperature sensors.
Omega is a direct manufacturer of many temperature sensors used by other equipment manufacturers, and it's much cheaper to work with Omega when sourcing replacement sensors. Omega is always my top choice for temperature sensors.

Just what we needed
The website was easy to follow and get to what I needed. The item was in stock and shipped promptly. As soon as it arrived, we installed it and put it to work. It got our heat treating oven back to work with minimum downtime.

Great wood-fired kiln thermocouples
We fire our wood kiln to cone 15 and really torture these thermocouples and they hold up well.

What pressure are these thermocouples rated for?
Thank you for your inquiry Ellie2022. To expand on my previous answer, the sealed metal sheath portion of probe is pressure rated for G or U junctions, but not for E since G and U can be used with a compression fitting. The TJ spring section is not pressure rated.

Hi, What is the max temperature rating for the wire that connects the probe to the K-type connector? It looks like plastic shielding on the wire and I don't want to melt it.
Thank you for your inquiry.
The max temperature the wire can handle is 260C (500F)

What length needs to be inserted into the process for an accurate reading with a 6inch probe?
Hi Peter, considering the thermocouple sensor is at the tip of the probe, it would be safe to assume 0.5-1 inch would be needed to get an accurate reading.

Can these be attached to a 2.5mm jack for use with a wireless bbq style type thermometer?
Hi Schwonkhead,
If your thermometer accepts a type K thermocouple then possibly yes. You'll need to check the wireless thermometer input specifications.
Best regards
OMEGA

What is the output of this sensor? Voltage or resistance change? Thanks.
This sensor produces millivolt output however resistance also varies based on ohms law.

Hello, Can this thermocouple be welded around section B? Also, is it able to withstand pressures to up to 500 psi? Thank you
The B section is where the Thermocouple wire is attached to the extension wire and potted. A tack weld could probably be made with a minimal amount of heat being applied. Omega does not pressure rate the probes but they do get used often in elevated pressures as what your inquiry suggests. If you need a probe with a pressure rating then the only one Omega offers is the pipe plug probe series.

Can I get this with a 10' lead?
Thank you for your inquiry. Yes we can make these as long as 50' using the CUSTOMIZE button.

I am looking for 2 stainless steel temperature probes to go into a 55 gallon drum that’s height is 34 inches. I want to hook it to a controller to manage a heating blanket to maintain a temperature between 68 to 75°F. What Would you recommend
This would need to be reviewed with a Temperature Engineer due to the complexity so please send an inquiry to temp@omega.com.
