Industrial PLS163-10-210-X4 Sludge Blanket Sensor Head Unit

Industrial PLS163-10-210-X4 Sludge Blanket Sensor Head Unit from Sensaras is the ultrasonic point-level head in the PLS-163 Series, designed to detect sludge blankets in clarifiers or tanks and automatically trigger pumps or valves to maintain the target blanket depth. 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.
