The A200-TEC15 is a Type-K ungrounded, fast response EGT thermocouple probe kit that will fit an exhaust with an outside diameter of 1 1/4" to 1 3/4". Using an Inconel 600 sheath these probes have been designed and tested for continuous operation exceeding 2200ºF! Short-term exposures to higher temperatures are also possible. The insulation shield is a non-vitrified high purity magnesium oxide (MgO). Superior resistance to oxidation attack results from a tenacious and protective high temperature film that does not affect the stability of the thermocouple alloys. This film permits the sensor to be used at ultra-high temperatures for prolonged periods with improved accuracy over other available sheath materials.
The probes are supplied with a 90º insertion bend but this can be reformed in the field based upon the specific installation. The probe is fused to the thermocouple conductor in a precision transition junction that protects the connection under all environmental conditions. Finally the measured potential is carried to the instrument using high temperature Teflon™ insulated thermocouple wire that can endure temperatures up to 500ºF. The connectors have a simple snap connection mechanism that allows easy removal and reattachment while retaining complete thermocouple junction integrity.
