Emerson Process Management”s Rosemount 5300 Series guided-wave radar level instrument features Direct Switch Technology (DST) for an echo signal that is two-to-five times stronger than other GWR transmitters. The improved signal-to-noise ratio means enhanced ability to handle difficult measuring conditions, like long measuring distances and lower dielectrics, also with a single lead probe. Applications include tanks, bridles, silos with solids, underground tanks, and liquid gas. The radar system features the same modular design, electronics, and robust housing as the Rosemount 5400 noncontacting radar. Electronics and cable connections are located in separate compartments, providing safer handling and improved moisture protection. The probes of the Rosemount 5300 provide multiple layers of protection, enabling reliable operation in high temperature and high pressure applications up to 752 F (400 C) or 5,000 PSIG (345 bar). The transmitter seal includes a temperature and pressure barrier in a flexible assembly to handle forces induced by probe movement and temperature variations. A second brazed hermetic, gas-tight seal provides another layer of protection, and the entire assembly is welded into a stainless-steel sleeve for total robustness. Probes are available in materials such as SST, Hastelloy, Monel, and PTFE-covered SST to withstand corrosive environments. FOUNDATION fieldbus, HART, and PlantWeb functionality allow the transmitter to integrate easily into new or existing control systems.
