Emerson introduces cryogenic seal for radar level sensors

Emerson Process Management has introduced a cryogenic seal for its Rosemount® 5300 series of high performance guided wave radar (GWR) level transmitters. The seal enables accurate, reliable level measurement of condensed and liquefied gasses at very low temperatures (to -196° C) and is ideal for use in process tanks, side chambers, storage tanks and transportation vessels.

The new transmitter seal provides multiple layers of protection using 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 additional protection. The entire assembly is welded into a stainless steel sleeve for total robustness.
