{"product_id":"temf-kompakt-temperatursensor-mit-schiffszulassung","title":"TEMF compact temperature sensor with marine approval","description":"\u003cp\u003eThe \u003cstrong\u003eTEMF\u003c\/strong\u003e is a modular compact temperature sensor with marine approval, manufacturer type Müller \u003cstrong\u003eMKTS-GL\u003c\/strong\u003e; the intrinsically safe version is called \u003cstrong\u003eMKTS-GLEx\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eIt measures directly in the medium, where high pressure and a harsh environment come together: \u003cstrong\u003e250 bar\u003c\/strong\u003e system pressure at \u003cstrong\u003e375 bar\u003c\/strong\u003e burst pressure; sensor tube, housing body and connector insert all in stainless steel \u003cstrong\u003e1.4571\u003c\/strong\u003e – the connector insert included, no plastic –, protection class \u003cstrong\u003eIP 65\u003c\/strong\u003e at the electronics and \u003cstrong\u003eIP 68\u003c\/strong\u003e at the sensor. Added to this the type approvals \u003cstrong\u003eDNV TAA00003GS\u003c\/strong\u003e and \u003cstrong\u003eEU RO MRA0000052\u003c\/strong\u003e, which apply to both versions.\u003c\/p\u003e\u003cp\u003eOne datasheet covers two versions: they differ in the approval and in the operating temperature – and in nothing else. The \u003cstrong\u003eMKTS-GLEx\u003c\/strong\u003e is additionally intrinsically safe, \u003cstrong\u003eII 1 G Ex ia IIC T6..T1 Ga\u003c\/strong\u003e for zones 0, 1 and 2 with gases; the MKTS-GL has \u003cstrong\u003eno explosion protection\u003c\/strong\u003e. The order codes are identical field by field, only the identifier changes from MK to GN.\u003c\/p\u003e\u003cp\u003eMeasurement is made with \u003cstrong\u003eone or two Pt100\u003c\/strong\u003e or \u003cstrong\u003ePt1000\u003c\/strong\u003e in 2-, 3- or 4-wire technology, in \u003cstrong\u003eclass A\u003c\/strong\u003e only, at 24-bit resolution. The measuring range runs from \u003cstrong\u003e-50 … +200 °C\u003c\/strong\u003e, the smallest span is \u003cstrong\u003e50 K\u003c\/strong\u003e. At the output, \u003cstrong\u003e4 … 20 mA\u003c\/strong\u003e, three voltage ranges or the resistance directly at the connector are available.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlease note before ordering:\u003c\/strong\u003e The accuracy of \u003cstrong\u003emax. 0.1 % of range\u003c\/strong\u003e applies only between 0 and +40 °C; below that, 0.0015 % per kelvin is added, above it 0.019 % – at +80 °C around 0.76 % on top, plus the error of the measuring element. Ambient temperature and medium temperature are two different things: the MKTS-GL works at \u003cstrong\u003e-40 … +85 °C\u003c\/strong\u003e, whereas for the MKTS-GLEx the limit depends on the temperature class and on the output type – current output -40 … +75 °C, voltage output only -40 … +50 °C, passive -50 … +100 °C. The medium temperature of the MKTS-GLEx is likewise tied to the temperature class: \u003cstrong\u003e+425 °C in T1\u003c\/strong\u003e, +275 °C in T2, +180 °C in T3, +115 °C in T4, +80 °C in T5 and \u003cstrong\u003e+65 °C in T6\u003c\/strong\u003e. Measuring range and medium temperature contradict each other in the source – feature list -50 … +200 °C, data table -50 … +425 °C: the transmitter measures only up to +200 °C, the 425 °C concern what the tube withstands; the lower value applies, and it should be confirmed before sizing. Both Ex certificate numbers end in X – \u003cstrong\u003eTÜV 21 ATEX 201293 X\u003c\/strong\u003e and \u003cstrong\u003eIECEx TUN 21.0005X\u003c\/strong\u003e – and carry special conditions; the source names heat flowing back, impact and friction as well as electrostatic charging. For none of the four certificates do we hold a document, only the numbers are substantiated; a \u003cstrong\u003eCE mark is not documented\u003c\/strong\u003e. The identifier is used more than once – MK for MKTS, MKTS-GL and MKTS-SP, GN for MKTS-Ex and MKTS-GLEx – which is why the type designation belongs in the order in plain text. Two measuring elements are available only without a transmitter; the insertion length (10 … 300 mm in 5 mm steps) must be stated. Configuration is done with the \u003cstrong\u003eDEV-KMA\u003c\/strong\u003e and the TrComm software.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMarine approval DNV TAA00003GS and EU RO MRA0000052, both versions\u003c\/li\u003e\n\u003cli\u003eMKTS-GLEx additionally Ex ia IIC T6..T1 Ga for zones 0, 1 and 2 with gases\u003c\/li\u003e\n\u003cli\u003eSystem pressure 250 bar, burst pressure 375 bar\u003c\/li\u003e\n\u003cli\u003eStainless steel 1.4571 right into the connector insert, IP 65 \/ IP 68\u003c\/li\u003e\n\u003cli\u003ePt100 or Pt1000 in class A, 24-bit resolution\u003c\/li\u003e\n\u003cli\u003e4 … 20 mA, voltage or resistance directly at the connector\u003c\/li\u003e\n\u003cli\u003eMedium temperature up to +425 °C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57041754194246,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/TEMF_produkt_c693e71c-2fdd-414d-ac46-12cf9d85c283.webp?v=1789734344","url":"https:\/\/octogon-sensors.com\/en\/products\/temf-compact-temperature-sensor-with-marine-approval","provider":"octogon GmbH","version":"1.0","type":"link"}
