{"product_id":"tkma-thermoelement-mit-anschlusskopf-b","title":"TKMA thermocouple with type B connection head","description":"\u003cp\u003eThe \u003cstrong\u003eTKMA\u003c\/strong\u003e is a thermocouple with connection head B, manufacturer type Müller \u003cstrong\u003eTE-MR1\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt is designed for permanent installation in pipes, tanks, and systems where the measuring point requires a wired connection. The aluminum \u003cstrong\u003econnection head\u003c\/strong\u003e is located above the process, accommodates a ceramic terminal block with connection posts, and routes the cable through an \u003cstrong\u003eM20x1.5\u003c\/strong\u003e gland; the process connection \u003cstrong\u003eM24x1.5\u003c\/strong\u003e is 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. Nominal lengths range from 50 to 1000 mm, with a maximum length of \u003cstrong\u003e2000 mm\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eTwo designs cover both mounting types: the screw-in sensor (ES) with process thread on the pipe and the immersion sensor (ET), which is mounted with accessories; available with twelve protection tube diameters from \u003cstrong\u003e1.5 to 15 mm\u003c\/strong\u003e. In the case of the mineral-insulated cable element, the first approximately \u003cstrong\u003e50 mm\u003c\/strong\u003e from the head are rigid, the rest flexible – allowing the sensor to be guided to the measuring point even without straight access. The manufacturer lists connection cables, compression fittings, and a \u003cstrong\u003etransmitter\u003c\/strong\u003e as accessories.\u003c\/p\u003e\n\u003cp\u003eThe measuring element is a thermocouple \u003cstrong\u003eType J (Fe-CuNi)\u003c\/strong\u003e or \u003cstrong\u003eType K (NiCr-Ni)\u003c\/strong\u003e, single or double, as a standard element or as a mineral-insulated cable element. The operating range for Type J is from \u003cstrong\u003e-200 ... +700 °C\u003c\/strong\u003e, 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 above ±0.004|t|. The thermoelectric voltage is available at the ceramic terminal block in the head, and the test voltage is \u003cstrong\u003e500 VDC\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBefore ordering, please note:\u003c\/strong\u003e The ambient temperature is not the medium temperature – the connection head is limited to \u003cstrong\u003e480 °C\u003c\/strong\u003e, while the measuring element reaches up to 1000 °C; here, the head, not the element, is decisive. The accuracy table for Type J extends to 750 °C, but the operating range up to 700 °C is authoritative. \u003cstrong\u003eIP 54 applies only to the connection head\u003c\/strong\u003e; the source does not specify a protection class for the protection tube. For the transmitter, it does not specify the type, output signal, or power supply, and terminal assignment is also missing. Weight, system pressure, CE mark, and explosion protection are not documented, and \u003cstrong\u003eDIN EN 60584-2 Class 1\u003c\/strong\u003e is not a product approval; this version does not have type approval. The GL version is the \u003cstrong\u003eTKMB\u003c\/strong\u003e (TE-MR1G, TAA00002H3); both carry the product identifier \u003cstrong\u003eKC\u003c\/strong\u003e, distinguished only by the first digit – 0 ... 3 for TKMA, 4 ... 7 for TKMB.\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\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\u003eConnection head B made of aluminum, IP 54, cable entry M20x1.5\u003c\/li\u003e\n\n\u003cli\u003eProtection tube 1.4571 or 2.4816, Ø 1.5 to 15 mm\u003c\/li\u003e\n\n\u003cli\u003eInstallation lengths 50 to 1000 mm, maximum length 2000 mm\u003c\/li\u003e\n\n\u003cli\u003eGL version TAA00002H3 available as TKMB\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57356926812486,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/TKMA_produkt_9d9cb0ff-142f-4e0c-bdbc-a8d86fe9c15e.webp?v=1789243685","url":"https:\/\/octogon.org\/en\/products\/tkma-thermocouple-with-type-b-connection-head","provider":"octogon GmbH","version":"1.0","type":"link"}
