The aluminum \u003cstrong\u003econnection head\u003c\/strong\u003e accommodates a ceramic base with connection posts, the process connection at the head is \u003cstrong\u003eM24x1.5\u003c\/strong\u003e, the cable entry is \u003cstrong\u003eM20x1.5\u003c\/strong\u003e, and the protection class is \u003cstrong\u003eIP 54\u003c\/strong\u003e.

The source does not list a transmitter as an accessory here, but it does include connection cables up to 6 m, compression fittings, and sheet metal flanges. Screw-in (ES) and immersion (ET) designs are available, as well as protection tube diameters of \u003cstrong\u003e3 to 15 mm\u003c\/strong\u003e; the selection is limited for the sheathed element and in the immersion design.\u003c\/p\u003e\n\u003cp\u003eThe measuring element is a \u003cstrong\u003ePt100\u003c\/strong\u003e or \u003cstrong\u003ePt1000\u003c\/strong\u003e, single or double, in a \u003cstrong\u003e2-, 3- or 4-wire circuit\u003c\/strong\u003e, as a standard element or as a sheathed element. The sensor's operating range is \u003cstrong\u003e-200 ... +450 °C\u003c\/strong\u003e, and the accuracy ranges in five steps from \u003cstrong\u003eClass A to B1\/10DIN\u003c\/strong\u003e. The resistance is at the ceramic base in the head, the test voltage is \u003cstrong\u003e500 VDC\u003c\/strong\u003e, and the response time on the 3×0.4 mm tube is \u003cstrong\u003et90 5 s\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBefore ordering, please note:\u003c\/strong\u003e The approval is documented by a mark and number, not by a certificate – the manufacturer's data sheet does not name a certifying body, and the certificate is not available. The language versions contradict each other regarding the sheath material: The English page names 2.4816 (Inconel 600), while the German page and the order codes in both languages name \u003cstrong\u003e1.4401 (316)\u003c\/strong\u003e – 1.4401 applies here. A response time is missing for the other tube geometries. The ambient temperature is not the medium temperature: The head is limited to \u003cstrong\u003e480 °C\u003c\/strong\u003e, the element ends at \u003cstrong\u003e450 °C\u003c\/strong\u003e. IP 54 only applies to the connection head; the source does not specify a standard for the accuracy classes, and terminal assignment, CE mark, and explosion protection are missing.
