{"product_id":"tbma-mantel-thermoelement","title":"TBMA mineral insulated thermocouple","description":"\u003cp\u003eThe \u003cstrong\u003eTBMA\u003c\/strong\u003e is a sheathed thermocouple with a flexible protection tube and a fixed connection cable, manufacturer type Müller \u003cstrong\u003eTE-MK1\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt measures in installation locations that a rigid protection tube cannot reach. The sheathed tube can be bent to a radius of \u003cstrong\u003emin. 5 × Ø protection tube\u003c\/strong\u003e; the cable is firmly attached to the sensor, eliminating the need for a connection head that requires space and wall clearance. The protection tube is made of \u003cstrong\u003e2.4816\u003c\/strong\u003e (Inconel 600), specified as a material up to \u003cstrong\u003e1100 °C\u003c\/strong\u003e, the connecting sleeve is made of \u003cstrong\u003e1.4571\u003c\/strong\u003e (316Ti), the protection class is \u003cstrong\u003eIP 65\u003c\/strong\u003e up to \u003cstrong\u003e250 °C\u003c\/strong\u003e. Available in four diameters from \u003cstrong\u003e1.5 to 6 mm\u003c\/strong\u003e and with a nominal length of \u003cstrong\u003e100 mm\u003c\/strong\u003e as standard, up to \u003cstrong\u003e2000 mm\u003c\/strong\u003e on request, it also fits into narrow and deep bores. Clamp fittings and sheet metal flanges from the accessories are used for fastening.\u003c\/p\u003e\n\u003cp\u003eFor \u003cstrong\u003eØ 3 mm\u003c\/strong\u003e, the manufacturer specifies a response time of \u003cstrong\u003et90 5 s\u003c\/strong\u003e and \u003cstrong\u003et50 2 s\u003c\/strong\u003e – meaning the sensor still responds usefully to rapid temperature changes. Connection is via open ends or via TE connectors in standard or mini design; five cable versions from PVC to glass silk are available, with a standard length of 2 m.\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, insulated in metal oxide. 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: \u003cstrong\u003e±1.5 °C\u003c\/strong\u003e in the range -40 … 375 °C, above that \u003cstrong\u003e±0.004|t|\u003c\/strong\u003e. The sensor directly outputs the thermovoltage; a transmitter is not documented; the insulation is tested with \u003cstrong\u003e500 VDC\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note before ordering:\u003c\/strong\u003e The operating range is determined by the cable, not the sensor – PVC ends at \u003cstrong\u003e+70 °C\u003c\/strong\u003e, silicone at \u003cstrong\u003e+180 °C\u003c\/strong\u003e, PTFE at \u003cstrong\u003e+250 °C\u003c\/strong\u003e, glass silk at \u003cstrong\u003e+550 °C\u003c\/strong\u003e. If you want to utilize the +1000 °C of Type K, you will not find a suitable cable in this cable range; for PTFE, the sister sheets specify \u003cstrong\u003e+205 °C\u003c\/strong\u003e, the value from this source is adopted. IP 65 does not apply to the version with braided shield; the source does not specify which protection class applies there. The accuracy table extends further than the operating range: Type J is listed there up to 750 °C, in the operating range up to 700 °C. Terminal assignment, process connection, system pressure, weight, CE mark and explosion protection are not documented. Every order code begins with the product identifier \u003cstrong\u003eKB\u003c\/strong\u003e, the temperature range used must be specified in °C. The version with GL type approval is the \u003cstrong\u003eTBMB\u003c\/strong\u003e (TE-MK1G).\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\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 sheathed tube, bending radius min. 5 × Ø protection tube\u003c\/li\u003e\n\n\u003cli\u003eFour diameters 1.5 · 3 · 4.5 · 6 mm, nominal length up to 2000 mm\u003c\/li\u003e\n\n\u003cli\u003eResponse time for Ø 3 mm t90 5 s and t50 2 s\u003c\/li\u003e\n\n\u003cli\u003eProtection tube 2.4816 (Inconel 600), material up to 1100 °C\u003c\/li\u003e\n\n\u003cli\u003eGL version available as TBMB (TE-MK1G)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57356927435078,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/TBMA_produkt_7a556a40-7d2f-4373-b0af-e6c840b05785.webp?v=1789243658","url":"https:\/\/octogon-sensors.com\/en\/products\/tbma-mineral-insulated-thermocouple","provider":"octogon GmbH","version":"1.0","type":"link"}
