The TC42 is available in Type J, Type K, and Type T thermocouple calibrations. The appropriate type depends on your operating temperature range, process environment, and application requirements. If you are unsure which thermocouple type is best, our technical team can help you select the right configuration.

The TC42 features an adjustable bayonet design that allows the immersion depth to be set during installation, ensuring the sensing tip is positioned at the correct measurement point. The spring-loaded bayonet provides up to 1 inch of compression, maintaining continuous pressure between the sensing tip and the measurement surface or sensing pocket. This helps minimize air gaps caused by vibration, thermal expansion, or equipment movement, resulting in more stable, repeatable, and reliable temperature measurements.

Yes. The TC42 can be configured with different sheath materials, probe diameters, immersion lengths, probe angles, junction styles, and connector options. This allows the sensor to be supplied for new OEM equipment or as a direct replacement for existing thermocouples.

For high-temperature applications, the thermocouple type is only one part of the selection process. You should also consider the sheath material, measuring junction, connector temperature rating, and the extension or lead wire insulation, as these components may have lower temperature limits than the sensing element itself. The operating environment, including oxidation, corrosion, vibration, pressure, and installation method, should also be evaluated to ensure long-term reliability. If you are unsure which configuration is best for your application, contact Tempotech Controls for technical assistance in selecting the most suitable thermocouple assembly.

The best choice depends on your application. Mineral Insulated (MgO) construction is recommended for higher temperatures, faster thermal response, greater mechanical strength, and applications exposed to vibration or harsh industrial environments. Tube & Wire construction is typically selected for lower-temperature applications where flexibility and cost are the primary considerations. If you are unsure which construction is best for your process, contact Tempotech Controls for application guidance and product selection.

Yes.
