Siemens Introduces SITRANS LR 250 Radar Level Transmitter
Atlanta, GA - Siemens Energy & Automation released the SITRANS LR 250 Radar Level transmitter with new 'Process Intelligence' advanced signal processing. This plug-and-play, compact, 25 GHz 2-wire device is the easiest to install and quickest to configure radar transmitter available on the market.
The new SITRANS LR 250 Radar Level transmitter can be used to measure a variety of liquid and slurry level applications accurately and reliably in minutes. Designed for measurements up to 66 feet, the new transmitter is well suited for chemical, pharmaceutical and hydrocarbon processing applications in corrosive atmospheres.
The compact radar horn antenna (from 1 ½" to 4" in diameter) allows for installation in smaller openings, and the narrow, high frequency beam ensures minimal interference from vessel walls. A high frequency, narrow transmission pulse means the complete vessel capacity can be measured. The multilingual Quick Start Wizard enables the user to set up the transmitter using only a few parameters allowing the SITRANS LR250 unit to be operational in minutes.
The transmitter can be programmed either locally with the intrinsically-safe, infrared handheld programmer or remotely using Simatic PDM (Process Device Manager) software. With PDM, there is no need to open the transmitter housing, which prevents exposing the unit's electronics to aggressive atmospheres.
A new graphical local user interface (LUI) displays echo profiles and diagnostic information enabling the user to determine the dynamics in the tank at a glance.
The SITRANS LR250 instrument also 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 in the tank to produce accurate and reliable level measurement readings. It allows the instrument to automatically ignore obstructions and is the processor behind more advanced features like the diagnostic tools, Quick Start Wizard, and Auto False-Echo Suppression. Additionally, it contains a new algorithm that improves the measurement accuracy at low levels in vessels containing low dielectric media.
