Product Description
The E+H PMD55 Differential Pressure Transmitter, a cutting - edge product from Endress+Hauser, stands as a testament to the company's commitment to innovation and excellence in industrial measurement technology. Engineered to meet the most demanding requirements of modern industrial processes, this differential pressure transmitter offers unparalleled accuracy, reliability, and versatility, making it an indispensable tool across a wide spectrum of industries, including oil and gas, chemical, power generation, and water treatment.
At the heart of the E+H PMD55 lies its sophisticated measuring principle, which is based on state - of - the - art silicon piezoresistive sensor technology. The differential pressure transmitter features a high - precision sensor module that consists of a sensing diaphragm. When differential pressure is applied across the diaphragm, it deforms slightly. This deformation causes a change in the electrical resistance of the piezoresistive elements integrated on the diaphragm.
The change in resistance is then converted into an electrical signal by the transmitter's internal circuitry. The relationship between the applied differential pressure and the resulting electrical signal is highly linear and precisely calibrated. To ensure utmost accuracy, the PMD55 incorporates advanced digital signal processing algorithms. These algorithms continuously monitor and compensate for various factors that could affect measurement accuracy, such as temperature variations, mechanical stress, and long - term drift.
For example, temperature fluctuations can cause the physical properties of the sensor materials to change, potentially leading to measurement errors. The built - in temperature compensation algorithms in the PMD55 analyze the temperature data from an integrated temperature sensor and adjust the measured differential pressure value accordingly. This way, the transmitter can provide highly accurate readings even in environments with significant temperature changes, ensuring reliable operation in diverse industrial settings.
Features
The sensor design of the PMD55 is optimized for performance and durability. The sensing diaphragm is made from high - quality silicon, which offers excellent mechanical properties, including high strength and resistance to fatigue. This ensures that the sensor can withstand high differential pressures and repeated stress cycles without degradation in performance over time. The sensor is also hermetically sealed to protect it from environmental contaminants, such as moisture, dust, and corrosive gases, further enhancing its reliability in harsh industrial environments.
The housing of the PMD55 is available in different materials, including aluminum and stainless steel, to suit various application requirements. Aluminum housings are lightweight yet robust, making them suitable for general industrial applications where the environmental conditions are not overly severe. They provide protection ratings like IP66 or NEMA 4X, which means they are dust - tight and can withstand powerful water jets from any direction. Stainless - steel housings, on the other hand, are designed for more challenging environments, such as those with high humidity, chemical exposure, or explosive atmospheres. They offer enhanced corrosion resistance and can meet stringent explosion - proof standards, making the PMD55 suitable for use in hazardous areas, such as oil refineries and chemical plants.
Product Overview
The PMD55 offers a comprehensive range of process connections to ensure seamless integration into existing industrial systems. Flange connections are available in various sizes and standards, including ANSI, DIN, and JIS, allowing for secure and leak - tight installation on pipes, vessels, and other process equipment. Threaded connections, such as NPT (National Pipe Thread) and BSP (British Standard Pipe), are also provided for applications where a quick and easy installation is required.
In addition, the transmitter features a flexible design that allows for different mounting orientations. This flexibility is crucial as it enables installation in tight spaces or in configurations that best suit the specific requirements of the process, without sacrificing measurement accuracy or accessibility for maintenance.
