Siemens have designed a new radar level transmitter, Sitrans LR250, with Process Intelligence advanced signal processing.
The plug-and-play compact 25 GHz 2-wire radar transmitter is easy to install and quick to configure. The level of liquids and slurries can be measured in minutes with reliability.
The new radar level transmitter is suitable for chemical, pharmaceutical and hydrocarbon processing applications, including corrosive environments.
The compact horn allows installation in small openings and the concentrated high frequency beam ensures interference from vessel walls is minimal. The Sitrans LR250 is equipped with a polyester powder-coated aluminium enclosure, an encapsulated electronics, glass antenna seal, stainless steel horn and optional hastelloy antenna material.
The multilingual Quick Start Wizard guides the user to programme the transmitter using the parameters and helps in measuring Sitrans LR250 in minutes stated Brad Stewart, product manager of Siemens.
The transmitter can be programmed through safe infrared handheld programmer and through a remote using Simatic PDM without opening the lid of the device, thus preventing exposure of the electronics to aggressive atmospheres.
The new graphical local user interface (LUI) displays echo profiles and diagnostic information allowing the user to determine the dynamics in the tank at a glance. The Sitrans LR250 includes self-diagnostic features that are communicated to the local display networks. For example, a timer can be preset to alert the user of a required maintenance and a scheduled quality check.
The Process Intelligence signal processing evaluates dynamic echo signals. It applies algorithms (based on field data collected from over one million level measurement applications) to raw echoes to produce an accurate and reliable level measurement readings.
It automatically ignores obstructions and is the processor behind the advanced features such as diagnostic tools, Quick Start Wizard and Auto False-Echo Suppression. The Process Intelligence also contains a new algorithm that improves the measurement accuracy in the low level of vessels containing low di-electric media.
