It is screwed directly into pipes, tanks, or units; the protective tube is made of stainless steel \u003cstrong\u003e1.4571\u003c\/strong\u003e, the system pressure is \u003cstrong\u003ePN 25\u003c\/strong\u003e, and the protection class is at least \u003cstrong\u003eIP 65\u003c\/strong\u003e. Compared to the other screw-in sensors in the series, it goes significantly higher in the medium: up to \u003cstrong\u003e+425 °C\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt has no display, buttons, or limit contacts; the measured value is sent as a current or voltage signal for evaluation, and settings are made with the \u003cstrong\u003eDEV-KMA\u003c\/strong\u003e configurator and TrComm software.\u003c\/p\u003e\n\u003cp\u003eMeasurements are taken with a \u003cstrong\u003ePt100 in a 2-wire circuit\u003c\/strong\u003e in Class A, B, or AA in the range of \u003cstrong\u003e-50 … +425 °C\u003c\/strong\u003e with a minimum span of 50 °C. The output offers a choice between \u003cstrong\u003e4 … 20 mA\u003c\/strong\u003e in 2-wire technology and \u003cstrong\u003evoltage signals such as 0 … 10 V\u003c\/strong\u003e in 3-wire technology. The accuracy is \u003cstrong\u003emax. 0.1 % of the measuring range\u003c\/strong\u003e plus sensor error at 24-bit resolution, powered by \u003cstrong\u003e12 … 30 VDC\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note before ordering:\u003c\/strong\u003e The data sheet specifies installation for gases in \u003cstrong\u003eZone 0, Zone 1, and Zone 2\u003c\/strong\u003e and lists three markings: \u003cstrong\u003eII 1 G Ex ia IIC T6..T1 Ga\u003c\/strong\u003e, \u003cstrong\u003eII 1\/2 G Ex ia IIC T6..T1 Ga\/Gb\u003c\/strong\u003e, and \u003cstrong\u003eII 2 G Ex ia IIC T6..T1 Gb\u003c\/strong\u003e; it does not explicitly state which marking is assigned to which zone. The certifications are \u003cstrong\u003eTÜV 21 ATEX 201293 X\u003c\/strong\u003e according to directive \u003cstrong\u003e2014\/34\/EU\u003c\/strong\u003e and \u003cstrong\u003eIECEx TUN 21.0005X\u003c\/strong\u003e. Both approval numbers end in X, which means special conditions apply; these are found in the operating instructions and not in the data sheet. The temperature class is given as T6..T1, not as a single value; according to the data sheet, the applicable class depends on the installation. The ambient temperature depends on the output type: -20 … +75 °C is permissible for the 2-wire current output, but only -20 … +50 °C for the 3-wire voltage output – anyone who orders the voltage output and designs for the upper value will be 25 K too high. And the ambient temperature is not the medium temperature: The medium can be up to +425 °C, but the electronics in the head cannot – above +85 °C, they can be destroyed. A CE mark is not documented in the data sheet, and a declaration of conformity is not available. The version without explosion protection, with display and two limit contacts, is the \u003cstrong\u003eTEMB\u003c\/strong\u003e (METS-WS).\u003c\/p\u003e\n\u003ch3\u003eAdvantages at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eIntrinsically safe, marking II 1 G Ex ia IIC T6..T1 Ga\u003c\/li\u003e\n\n\u003cli\u003eATEX TÜV 21 ATEX 201293 X and IECEx TUN 21.0005X\u003c\/li\u003e\n\n\u003cli\u003eInstallation for gases in Zone 0, Zone 1, and Zone 2\u003c\/li\u003e\n\n\u003cli\u003ePt100 in 2-wire circuit, medium -50 … +425 °C\u003c\/li\u003e\n\n\u003cli\u003eAccuracy max. 0.1 % of measuring range, 24-bit resolution\u003c\/li\u003e\n\n\u003cli\u003e4 … 20 mA in 2-wire or 0 … 10 V in 3-wire technology\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57356928418118,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/TEMD_produkt_f90bbf88-8064-40a9-86cc-c3af619fcca9.webp?v=1789243685","url":"https:\/\/octogon-sensors.com\/en\/products\/temd-einschraub-temperatursensor-ex-mets-wtex","provider":"octogon GmbH","version":"1.0","type":"link"}
