The Allen-Bradley 871TM-DR5NE18-H2 and 871TM-DX28-H5 sensors are versatile and reliable components in Rockwell Automation's offering for level measurement applications. These level switches, part of the 871TM series, are designed to provide accurate and consistent detection of level changes in various types of liquids or bulk solids.
The 871TM-DR5NE18-H2 is a guided microwave level switch. It utilizes non-contacting microwave technology to measure levels in tanks or vessels. This model is particularly suitable for applications where there are obstructions or dense media, as the microwave beam is guided by a metal probe, allowing it to effectively penetrate through the media and provide accurate level measurements. The 871TM-DR5NE18-H2 is well-suited for applications in the water and wastewater, oil and gas, and power generation industries.
The 871TM-DX28-H5, on the other hand, is a guided radar level switch. This model employs radar technology to measure level in a non-contacting manner. The use of radar technology enables the sensor to detect the interface between different media, making it ideal for applications with floating or submerged targets. The 871TM-DX28-H5 is suitable for applications in the food and beverage, chemical, pharmaceutical, and oil and gas industries, among others.
Both sensors feature a rugged, compact design and are constructed with high-quality materials, ensuring long-lasting performance in demanding environments. They offer a wide range of process connection options, including threaded, flanged, and welded, allowing for easy integration into various process systems.
The Allen-Bradley 871TM-DR5NE18-H2 and 871TM-DX28-H5 sensors are equipped with advanced diagnostic capabilities, enabling users to quickly identify and resolve any potential issues. Their user-friendly design and intuitive communication protocols, such as HART and Foundation Fieldbus, make them easy to install, configure, and maintain.
By choosing the Allen-Bradley 871TM-DR5NE18-H2 or 871TM-DX28-H5 sensor for your level measurement needs, you can trust in their accuracy, reliability, and versatility to optimize your process operations and enhance overall plant performance.
The Allen Bradley 871TM-DR5NE18-H2 and 871TM-DX28-H5 sensors are crucial components in various automation applications. In this analysis, we will discuss the key features, advantages, and disadvantages of these sensors to help you make an informed decision.
