Technically, it is the sensor of the \u003cstrong\u003eTE-MK1\u003c\/strong\u003e, but more narrowly defined – the nominal length is limited to \u003cstrong\u003e200 mm\u003c\/strong\u003e, and the connection cable to \u003cstrong\u003e6 m\u003c\/strong\u003e. The sheath remains flexible with a minimum bending radius of \u003cstrong\u003e5 × Ø protection tube\u003c\/strong\u003e, reaching installation locations that a rigid protection tube cannot; the cable is firmly attached to the sensor, eliminating the need for a connection head. Protection tube \u003cstrong\u003e2.4816\u003c\/strong\u003e (Inconel 600) and connection sleeve \u003cstrong\u003e1.4571\u003c\/strong\u003e (316Ti) provide \u003cstrong\u003eIP 65\u003c\/strong\u003e up to \u003cstrong\u003e250 °C\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eDiameters and wall thicknesses are specified as \u003cstrong\u003e1.9×0.2\u003c\/strong\u003e, \u003cstrong\u003e3×0.25\u003c\/strong\u003e, \u003cstrong\u003e4.5×0.36\u003c\/strong\u003e, and \u003cstrong\u003e6×0.51 mm\u003c\/strong\u003e, with a standard nominal length of \u003cstrong\u003e100 mm\u003c\/strong\u003e. Connection is made via open ends or via TE connectors in standard or mini form; five cable types from PVC to glass fiber are available. Clamp fittings and sheet metal flanges from the accessories are used for fastening.\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, insulated in metal oxide. 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: \u003cstrong\u003e±1.5 °C\u003c\/strong\u003e in the range -40 … 375 °C, and above that \u003cstrong\u003e±0.004|t|\u003c\/strong\u003e. The sensor outputs the thermovoltage directly; a transmitter is not documented; the insulation is tested with \u003cstrong\u003e500 VDC\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote before ordering:\u003c\/strong\u003e The approval is proven by a mark and number, not by a certificate; the certificate should be requested before any assurance is given to the classification society. Both versions carry the product designation \u003cstrong\u003eKB\u003c\/strong\u003e; they are distinguished solely by the thermocouple type digit: \u003cstrong\u003e2 · 3\u003c\/strong\u003e is the TE-MK1G, \u003cstrong\u003e0 · 1\u003c\/strong\u003e is the TE-MK1 – a digit swap orders the sensor without approval. The operating range is determined by the cable, not the sensor: PVC ends at +70 °C, silicone at +180 °C, PTFE at +250 °C, glass fiber at +550 °C; for PTFE, the sister sheets state +205 °C. IP 65 does not apply to the version with braided shield. Terminal assignment, process connection, system pressure, weight, response time, CE mark, and explosion protection are not documented. The version without approval, with a nominal length of \u003cstrong\u003e2000 mm\u003c\/strong\u003e, is the \u003cstrong\u003eTBMA\u003c\/strong\u003e (TE-MK1).\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eType approval GL TAA00002H3 proven by mark and number\u003c\/li\u003e\n\n\u003cli\u003eThermocouple Type J or Type K, -200 … +1000 °C\u003c\/li\u003e\n\n\u003cli\u003eLimit deviation Class 1 according to DIN EN 60584-2, ±1.5 °C from -40 °C\u003c\/li\u003e\n\n\u003cli\u003eFlexible sheath, bending radius min. 5 × Ø protection tube\u003c\/li\u003e\n\n\u003cli\u003eFour diameters with wall thickness: 1.9×0.2 to 6×0.51 mm\u003c\/li\u003e\n\n\u003cli\u003eNominal length 100 mm as standard, maximum 200 mm\u003c\/li\u003e\n\n\u003cli\u003eProtection tube 2.4816 (Inconel 600), connection cable maximum 6 m\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57356927729990,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/TBMB_produkt_38995495-5526-44d4-9bde-7f3262e5d4e4.webp?v=1789243659","url":"https:\/\/octogon-sensors.com\/en\/products\/tbmb-mineral-insulated-thermocouple-gl","provider":"octogon GmbH","version":"1.0","type":"link"}
