Extreme Environment Level Transmitter

July 1, 2006
The Rosemount 3300 Series Guided Wave Radar Level and Interface Transmitter has been expanded to enhance safety and efficiency in extreme environments.

The expansion includes special probes designed to prevent leakage and perform reliably when exposed to high temperature and pressure conditions over extended periods. The 3300 is now available for temperatures up to 750ºF (400ºC) and pressures up to 5000psig (345 bars). Materials for the special 3300 probes were selected to avoid stress fracture commonly induced by high pressures and temperatures. The new high temperature and pressure tank seal provides multiple layers of protection to avoid issues that can result from leakage. The seal includes a pressure and temperature 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.
