About Rosemount 5300 Level Transmitter

Guided wave radar can unlike many other technologies, detect interfaces. An interface is when you have more than one type of media with a different density, which creates two layers. Interface measurement is needed in applications where you want to know if, or how much of a top layer is present.

The Rosemount 5300 uses a Peak-in-Peak thin layer detection technology which can detect and distinguish two surfaces normally seen as one. The advanced algorithm makes it possible to detect top layers down to 1 inch (25 mm).

Direct Switch Technology is a unique feature that enhances signal strength for more reliable and robust measurements and safer operations, even in tough conditions.

A significantly stronger signal translates into a more user friendly device with greater application flexibility. It also enables the use of low maintenance single lead probes instead of the more common higher maintenance coaxial probes.

Guided wave radars use either a single lead, twin lead or coaxial probe. They can be flexible, rigid, segmented and are available in many types of material to fit most applications.

The single lead probe is most common and a perfect fit for highly viscous, thick or dirty media, and most resistant to build-ups. Coaxial probes are suitable when you have disturbing objects, turbulence, tall and narrow nozzles or bottle neck shaped cages for instance. A twin lead probe is good for viscous media and nearby objects.

Verify measurement integrity without climbing tanks or changing level to ensure safe operation between tests. With the verification reflector you can perform comprehensive 2 point remote proof-testing with 94% coverage at the DCS. This can be done during operation, without raising the tank level to potentially hazardous levels, for minimized risk and maximized safety in minutes.

The large coaxial probe is designed to ensure highly reliable level- and interface measurement all the way to the top, during emptying, filling and restarts without losing track of the surfaces.

It does not use any reference pulse which enables a stronger signal to be sent out and recieved, and together with the direct switch technology you can be sure to trust your device. The seamless slots provide accurate interface measurement throughout the entire measurement range.

A robust and accurate level measurement is required for saturated steam applications and extreme operating conditions. Dynamic Vapor Compensation is a feature that ensures high accuracy level measurement in these applications.

Microwave pulses move more slowly in saturated steam than in air, as a result the surface appears to be lower than it actually is. By using a probe with an integrated reference reflector, the Rosemount 5300 uses the vapor dielectric constant and the speed of the pulse in the steam to find the true level.

Signal Quality Metrics is a unique diagnostics function which proactively alerts the operator ahead of potential issues by tracking probe coating/build-up and reacting in the case of issues caused by heavy foaming.

Sticky products may coat the probe. If the coating becomes too thick, the level signal becomes weaker and maintenance needs to be carried out. With Signal Quality Metrics, the operator can track signal quality and receive notification when the quality degrades. 

Probe End Projection helps the radar to calculate the signal when the signal is degraded, with a seamless transition between the different measurement modes. The radar wave propagation speed depends on the dielectric constant of the medium, and by knowing the exact length of the probe, it is possible to use the reflection from the probe end to calculate the level.

With Probe End Projection, the Rosemount 5300 handles applications where the dielectric constant is very low, and over very long ranges without any problem.
