Product Description

Product Overview

In the complex and highly demanding realm of industrial process control, accurate level measurement of liquids is of paramount importance. Whether it's in chemical plants, oil and gas refineries, water treatment facilities, or storage terminals, precise knowledge of liquid levels ensures efficient operations, safety, and optimal resource management. The Siemens SITRANS Probe LR 200 Series 7ML5422-2AA30 Radar Level Transmitter emerges as a cutting - edge solution in this field, offering unparalleled accuracy, reliability, and versatility. Developed by Siemens, a global leader in industrial automation and technology, this radar level transmitter leverages advanced radar technology to provide continuous and highly accurate level measurements, even in the most challenging industrial environments. Its innovative design, combined with a host of intelligent features, makes it an ideal choice for a wide range of applications, revolutionizing the way industries monitor and control liquid levels.

Specification

Low Maintenance Requirements
Thanks to its robust design and advanced self - monitoring capabilities, the SITRANS Probe LR 200 Series 7ML5422-2AA30 has minimal maintenance requirements. The transmitter continuously monitors its own performance and can detect potential issues, such as sensor malfunctions, communication problems, or abnormal signal patterns. It provides detailed diagnostic information that can be easily accessed by operators, either locally through the operator interface or remotely via digital communication protocols.
The use of radar technology also eliminates many of the common maintenance issues associated with other level measurement methods. Unlike mechanical level sensors, which may suffer from wear and tear over time, or ultrasonic sensors that may require frequent calibration due to changes in environmental conditions, the 7ML5422-2AA30 offers long - term reliability with minimal maintenance. 

Working Principle

The SITRANS Probe LR 200 Series 7ML5422 - 2AA30 operates based on the principle of radar technology. It emits low - power microwave pulses at a frequency of 6 GHz (5.8 GHz in most regions, 6.3 GHz in North America). These microwave pulses are transmitted from the antenna towards the surface of the liquid or slurry in the tank. When the pulses encounter the interface between the air (or gas in the tank) and the liquid, a portion of the energy is reflected back towards the transmitter.
