{"product_id":"tbmd-mantel-widerstandsthermometer-gl","title":"TBMD mineral insulated resistance thermometer, GL","description":"\u003cp\u003eThe \u003cstrong\u003eTBMD\u003c\/strong\u003e is a sheathed resistance thermometer with GL type approval, manufacturer type Müller \u003cstrong\u003eWT-MK1G\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt is designed for systems where the sensor must carry a type approval from Germanischer Lloyd: \u003cstrong\u003eGL TAA00002H5\u003c\/strong\u003e. Compared to the \u003cstrong\u003eWT-MK1\u003c\/strong\u003e, the nominal length is limited to \u003cstrong\u003e200 mm\u003c\/strong\u003e and the connection cable to \u003cstrong\u003e6 m\u003c\/strong\u003e, but there is an additional diameter of \u003cstrong\u003e1.9 mm\u003c\/strong\u003e, which also fits into narrow boreholes. The sheath remains flexible with a minimum bending radius of \u003cstrong\u003e5 × Ø protection tube\u003c\/strong\u003e and reaches installation locations that a rigid protection tube cannot; the cable is fixed, and no connection head is required.\u003c\/p\u003e\n\u003cp\u003eProtection tube \u003cstrong\u003e1.4401\u003c\/strong\u003e (316), specified as a material up to \u003cstrong\u003e600 °C\u003c\/strong\u003e, and connection sleeve \u003cstrong\u003e1.4571\u003c\/strong\u003e (316Ti) carry \u003cstrong\u003eIP 65\u003c\/strong\u003e up to \u003cstrong\u003e250 °C\u003c\/strong\u003e; the nominal length is standard at \u003cstrong\u003e100 mm\u003c\/strong\u003e. Connection is made via open ends with wire end ferrules; five cable versions from PVC to glass silk are available. Compression fittings and sheet metal flanges are accessories.\u003c\/p\u003e\n\u003cp\u003eThe measuring element is a \u003cstrong\u003ePt100\u003c\/strong\u003e or \u003cstrong\u003ePt1000\u003c\/strong\u003e, single or double, insulated in metal oxide and wired in \u003cstrong\u003e2-, 3- or 4-wire\u003c\/strong\u003e circuitry. The sensor's operating range extends from \u003cstrong\u003e-200 to +450 °C\u003c\/strong\u003e, and accuracy can be selected in five steps from \u003cstrong\u003eClass A\u003c\/strong\u003e to \u003cstrong\u003eB1\/10DIN\u003c\/strong\u003e. The sensor outputs resistance directly; a transmitter is not documented; 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 documented as a mark and number, not as a certificate; the certificate should be requested before any assurance is given to the classification society. Both versions bear the product identification \u003cstrong\u003eKM\u003c\/strong\u003e; they are distinguished solely by the sensor element position: \u003cstrong\u003e4 ... 7\u003c\/strong\u003e is the WT-MK1G, \u003cstrong\u003e0 ... 3\u003c\/strong\u003e is the WT-MK1 - a digit reversal 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 +205 °C, glass silk at +550 °C - only the glass silk version reaches the sensor's +450 °C. The source does not specify a standard for the accuracy classes. IP 65 does not apply to the version with braided shield. Wall thickness, 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\u003eTBMC\u003c\/strong\u003e (WT-MK1).\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eType approval GL TAA00002H5 documented as a mark and number\u003c\/li\u003e\n\n\u003cli\u003ePt100 or Pt1000, single or double, -200 ... +450 °C\u003c\/li\u003e\n\n\u003cli\u003eCircuitry in 2-, 3- or 4-wire, Class A to B1\/10DIN\u003c\/li\u003e\n\n\u003cli\u003eFour diameters 1.9 · 3 · 4.5 · 6 mm, one more than the TBMC\u003c\/li\u003e\n\n\u003cli\u003eFlexible sheath, bending radius min. 5 × Ø protection tube\u003c\/li\u003e\n\n\u003cli\u003eNominal length 100 mm as standard, maximum 200 mm\u003c\/li\u003e\n\n\u003cli\u003eProtection tube 1.4401 (316), connection cable maximum 6 m\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57356928549190,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/TBMD_produkt_9be15878-5282-42b0-bac6-38484c92125f.webp?v=1789243659","url":"https:\/\/octogon-sensors.com\/en\/products\/tbmd-mineral-insulated-resistance-thermometer-gl","provider":"octogon GmbH","version":"1.0","type":"link"}
