The handle and protective tube are made of stainless steel \u003cstrong\u003e1.4571\u003c\/strong\u003e, and the protective tube measures \u003cstrong\u003eØ 6 × 0.5 mm\u003c\/strong\u003e. The tube length is available from \u003cstrong\u003e50 to 1000 mm\u003c\/strong\u003e, with the tube end flat, pointed, or optionally heated. The weight is approximately \u003cstrong\u003e450 g\u003c\/strong\u003e, and the protection class is at least \u003cstrong\u003eIP 65 with the connection plugged in\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe same handle can be ordered with very different outputs: the \u003cstrong\u003ePt100(0) directly on the connector\u003c\/strong\u003e and thus without power supply, \u003cstrong\u003e4 … 20 mA with HART\u003c\/strong\u003e in the 2-wire loop, or digital \u003cstrong\u003eCANopen\u003c\/strong\u003e, Modbus RTG, and \u003cstrong\u003ePROFIBUS DP\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe input features a \u003cstrong\u003ePt100\u003c\/strong\u003e or \u003cstrong\u003ePt1000\u003c\/strong\u003e in 2-, 3- or 4-wire configuration in classes \u003cstrong\u003eA, B, and B 1\/2 DIN\u003c\/strong\u003e. The resolution is \u003cstrong\u003e16 bit\u003c\/strong\u003e, the accuracy \u003cstrong\u003e0.2 K or 0.08 % of the range\u003c\/strong\u003e, the response time \u003cstrong\u003e1 s\u003c\/strong\u003e; calibration is performed via \u003cstrong\u003e2 or 6 points\u003c\/strong\u003e, set via the HART tool. The HART loop requires \u003cstrong\u003e12 … 40 VDC\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note before ordering:\u003c\/strong\u003e For a handheld device, two safety-relevant specifications are missing: a permissible handle or hand temperature and a maximum immersion depth are not documented in the manufacturer's data sheet – anyone measuring at +200 °C must determine for themselves how far the tube may be immersed and whether the handle is still touchable. The ambient temperature is not the medium temperature: permissible are -40 … +85 °C ambient and -50 … +200 °C medium. The source does not state which of the two accuracy specifications – 0.2 K or 0.08 % of the range – applies. The fault message is 3.8 mA at the lower end of the usable range of 3.8 … 20.8 mA; a wire break cannot be distinguished from a measurement at the beginning of the range. The heated tip is in the order key, but not in any data line – neither power nor voltage nor control; it must be requested from the manufacturer. Not every connection carries every signal: Two sensors in 3-wire connection only work with M12 eight-pin, AMP MIL, and cable; Super Seal and Deutsch DT04 three-pin do not carry the heating. The source writes \u003cstrong\u003eModbus RTG\u003c\/strong\u003e; such a protocol does not exist, Modbus RTU is meant. The data sheet does not mention a system pressure, a protection class in the unplugged state, a CE mark, a declaration of conformity, or explosion protection.\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eHandle and protective tube made of stainless steel 1.4571, Ø 6 × 0.5 mm\u003c\/li\u003e\n\n\u003cli\u003eTube length 50 to 1000 mm, tube end flat, pointed or heated\u003c\/li\u003e\n\n\u003cli\u003ePt100 or Pt1000 in 2-, 3- or 4-wire connection\u003c\/li\u003e\n\n\u003cli\u003eClasses A, B and B 1\/2 DIN, medium -50 … +200 °C\u003c\/li\u003e\n\n\u003cli\u003eResistance directly, 4 … 20 mA with HART or digital\u003c\/li\u003e\n\n\u003cli\u003eAccuracy 0.2 K or 0.08 % of the range, response time 1 s\u003c\/li\u003e\n\n\u003cli\u003eIP 65 with plugged-in connection, weight approximately 450 g\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57356932251974,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/THMA_produkt_2cf31cdd-001a-4836-8380-d673d5417192.webp?v=1789243685","url":"https:\/\/octogon-sensors.com\/en\/products\/thma-hand-temperatursensor-mkts-ha","provider":"octogon GmbH","version":"1.0","type":"link"}
