Built with a rugged 316L stainless steel probe and a ¾\" NPT process connection, the head unit houses the electronic module in a NEMA 4\/7 explosion‑proof enclosure and includes an LED status indicator for at‑a‑glance operation; it operates with no moving parts, leveraging ultrasonic technology that is unaffected by color, viscosity, dielectric constant, or density. The system accepts 90–240 VAC input and offers a 10 A DPDT output option (with alternative Loop Power 4–16 mA configurations), and supports a 24 VDC input option along with a field‑selectable fail‑safe mode and a built‑in self‑test push button to verify functionality. Operating temperatures range from -20°C to 150°C, and cable lengths up to 50 inches are available to accommodate a variety of installation geometries. \u003c\/p\u003e\u003c\/div\u003e","brand":"Sensaras","offers":[{"title":"New","offer_id":46283448385770,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-020.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/industrial-pls163-10-210-x4-sludge-blanket-sensor-head-unit","provider":"GTG Hardware","version":"1.0","type":"link"}
