The sheathed tube can be bent to a radius of \u003cstrong\u003emin. 5 × Ø protective tube\u003c\/strong\u003e; the cable is firmly attached to the sensor, eliminating the need for a connection head. Protective tube \u003cstrong\u003e1.4401\u003c\/strong\u003e (316), specified as a material up to \u003cstrong\u003e600 °C\u003c\/strong\u003e, and connecting sleeve \u003cstrong\u003e1.4571\u003c\/strong\u003e (316Ti) provide \u003cstrong\u003eIP 65\u003c\/strong\u003e up to \u003cstrong\u003e250 °C\u003c\/strong\u003e. Available in \u003cstrong\u003e3 · 4.5 · 6 mm\u003c\/strong\u003e diameters with a wall thickness of 0.25 to 0.51 mm, the standard nominal length is \u003cstrong\u003e100 mm\u003c\/strong\u003e, up to \u003cstrong\u003e2000 mm\u003c\/strong\u003e on request. Compression fittings and sheet metal flanges are available as accessories.\u003c\/p\u003e\n\u003cp\u003eThe sensor is sluggish: for \u003cstrong\u003e6×0.5 mm\u003c\/strong\u003e, the manufacturer states \u003cstrong\u003et90 30.9 s\u003c\/strong\u003e and t50 12 s; for \u003cstrong\u003e6×1 mm\u003c\/strong\u003e, \u003cstrong\u003et90 22.1 s\u003c\/strong\u003e and t50 7.6 s. Connection is via open ends with wire end ferrules; five cable types from PVC to glass silk are available.\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 configuration. The sensor's operating range extends from \u003cstrong\u003e-200 ... +450 °C\u003c\/strong\u003e, with accuracy selectable in five stages from \u003cstrong\u003eClass A\u003c\/strong\u003e to \u003cstrong\u003eB1\/10DIN\u003c\/strong\u003e. The sensor outputs the resistance directly; a transmitter is not documented; insulation is tested with \u003cstrong\u003e500 VDC\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBefore ordering, please note:\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+205 °C\u003c\/strong\u003e, glass silk at \u003cstrong\u003e+550 °C\u003c\/strong\u003e; only the glass silk version reaches the +450 °C of the sensor. Two four-wire sensors are only available with PTFE-silicone cable, so this version ends at +180 °C. The source does not specify any standard for the accuracy classes – if a class needs to be guaranteed, it must be confirmed by the manufacturer. The two response times contradict each other: the thicker 6×1 mm wall is stated as faster, and 1 mm is not in the wall thickness table. IP 65 does not apply to the version with braided shielding. Terminal assignment, process connection, system pressure, weight, CE mark, and explosion protection are not documented. Each order code begins with the product identifier \u003cstrong\u003eKM\u003c\/strong\u003e, the used temperature range must be specified in °C. The version with GL type approval is the \u003cstrong\u003eTBMD\u003c\/strong\u003e (WT-MK1G).\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003ePt100 or Pt1000, single or double, -200 ... +450 °C\u003c\/li\u003e\n\n\u003cli\u003eWiring in 2-, 3- or 4-wire freely selectable\u003c\/li\u003e\n\n\u003cli\u003eFive accuracy classes from Class A to B1\/10DIN\u003c\/li\u003e\n\n\u003cli\u003eFlexible sheathed tube, bending radius min. 5 × Ø protective tube\u003c\/li\u003e\n\n\u003cli\u003eThree diameters 3 · 4.5 · 6 mm, nominal length up to 2000 mm\u003c\/li\u003e\n\n\u003cli\u003eProtective tube 1.4401 (316), material up to 600 °C\u003c\/li\u003e\n\n\u003cli\u003eGL version available as TBMD (WT-MK1G)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57356928319814,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/TBMC_produkt_72d26594-15bb-4ddd-b26c-1ce689988940.webp?v=1789243659","url":"https:\/\/octogon-sensors.com\/en\/products\/tbmc-mineral-insulated-resistance-thermometer","provider":"octogon GmbH","version":"1.0","type":"link"}
