2-wire radar level transmitter is easy
to install
The new Siemens 2-wire 25GHz radar level transmitter, the Sitrans LR250, has 'Process Intelligence' advanced signal processing, making it easy to install and the quickest to configure
The level of liquids or slurries can be accurately and reliably measured in minutes The new Sitrans LR250 can be used in general applications, but is also suitable for chemical, pharmaceutical and hydrocarbon processing applications, including corrosive environments

A new compact radar level transmitter from Siemens
The new Sitrans LR250 radar level transmitter is designed for the continuous monitoring of liquids and slurries in storage and process vessels including those at high temperature and pressure
Profibus PA added to radar level transmitters
Siemens Automation and Drives has added Profibus PA interfaces to their Sitrans LR250 and Sitrans LR460 radar level transmitters
The compact horn allows installation in small openings and the concentrated high frequency beam ensures interference from vessel walls is minimal.
A high frequency and narrow transmission pulse means the complete vessel capacity can be measured.
The multilingual Quick Start Wizard guides you to programme the transmitter using a few parameters, and has the Sitrans LR250 measuring in minutes.
The transmitter can be programmed via the intrinsically safe infrared hand-held programmer or remotely using a 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 dynamics in the tank at a glance.
The Sitrans LR250 includes self-diagnostic features that are communicated to the local display and across networks.
For example, a timer can be preset to alert the user of a required maintenance or a scheduled quality check.
The new '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 accurate and reliable level measurement readings.
It can automatically ignore obstructions and is the processor behind the more advanced features such as diagnostic tools, Quick Start Wizard and Auto False-Echo Suppression.
It also contains a new algorithm that improves the measurement accuracy in the low level of vessels containing low dielectric media.
