The aluminum \u003cstrong\u003econnection head\u003c\/strong\u003e accommodates a ceramic base with connection posts. The process connection \u003cstrong\u003eM24x1.5\u003c\/strong\u003e and the cable gland \u003cstrong\u003eM20x1.5\u003c\/strong\u003e are located on the head, and the protection class is \u003cstrong\u003eIP 54\u003c\/strong\u003e. The protection tube made of \u003cstrong\u003e1.4571 (316Ti)\u003c\/strong\u003e or \u003cstrong\u003e2.4816 (Inconel 600)\u003c\/strong\u003e withstands temperatures up to 600 °C or 1100 °C respectively, and the process pressure is \u003cstrong\u003emax. PN16\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eCompared to the TKMA, this is not the same product with an additional marking: This version is limited to a length of \u003cstrong\u003e200 mm\u003c\/strong\u003e instead of 2000 mm and has a different accessory set. The source does not list a transmitter here as an accessory, but it does include connection cables up to 6 m, compression fittings, and a sheet metal flange. Screw-in (ES) and immersion (ET) designs are available, as well as protection tube diameters of \u003cstrong\u003e3 to 15 mm\u003c\/strong\u003e; the selection is limited for mineral insulated elements and in the immersion design.\u003c\/p\u003e\n\u003cp\u003eThe measuring element is a \u003cstrong\u003eType J (Fe-CuNi)\u003c\/strong\u003e or \u003cstrong\u003eType K (NiCr-Ni)\u003c\/strong\u003e thermocouple, single or double, as a standard element or as a mineral insulated element. The operating range for Type J is from \u003cstrong\u003e-200 ... +700 °C\u003c\/strong\u003e, and for Type K from \u003cstrong\u003e-200 ... +1000 °C\u003c\/strong\u003e; the limit deviation follows \u003cstrong\u003eDIN EN 60584-2 Class 1\u003c\/strong\u003e with \u003cstrong\u003e±1.5 °C\u003c\/strong\u003e from -40 ... 375 °C and ±0.004|t| above. The thermovoltage is available at the ceramic base in the head, the test voltage is \u003cstrong\u003e500 VDC\u003c\/strong\u003e, and the response time on the 3x0.4 mm tube is \u003cstrong\u003et90 6 s\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note before ordering:\u003c\/strong\u003e The approval is documented as a mark and number, not as a certificate – the manufacturer's sheet does not mention a certifying body, and the certificate is not available; it should be requested before any assurance. Both bear the product identification \u003cstrong\u003eKC\u003c\/strong\u003e, distinguished solely by the first digit of the order code: \u003cstrong\u003e4 ... 7\u003c\/strong\u003e for the TKMB, 0 ... 3 for the TKMA – the English version prints 0 ... 3 for the GL variant here, which would make it unorderable unnoticed. The ambient temperature is not the medium temperature: The head is limited to \u003cstrong\u003e480 °C\u003c\/strong\u003e, the measuring element reaches up to 1000 °C. The source states 15 s for the 6x0.5 mm tube here, while the TKMA sheet states 30.9 s – it does not explain the difference. IP 54 applies only to the connection head; terminal assignment, CE mark, and explosion protection are not documented.\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eGL type approval TAA00002H3, documented as a mark and number\u003c\/li\u003e\n\n\u003cli\u003eThermocouple Type J or Type K, single or double\u003c\/li\u003e\n\n\u003cli\u003eOperating range Type J -200 ... +700 °C, Type K -200 ... +1000 °C\u003c\/li\u003e\n\n\u003cli\u003eProcess pressure max.
