The Lumenite PHS41AST is a new liquid level probe designed for point-level detection in industrial liquid control and monitoring applications. The probe features a ceramic (alumina) electrode rod approximately 12 inches in length, mounted through a threaded stainless steel fitting with a hex locknut, and a stainless steel mounting block housing with spring-clip retention tabs and a large-bore threaded side port for pipe or vessel installation. The stainless steel electrode housing block includes internal terminal connections visible through the open face, with the ceramic rod serving as the sensing element for conductive liquid level detection — the assembly is compatible with Lumenite Electronic Liquid Level Controls as a replacement or original probe assembly. The unit is supplied new-in-box with protective packaging and includes hardware accessories.
