Product Description
The E+H PMD75 Differential Pressure Transmitter stands as a pinnacle of innovation and reliability in the realm of industrial process measurement. Manufactured by Endress+Hauser, a global titan in the field of automation instrumentation, the PMD75 is meticulously engineered to meet the most demanding requirements of modern industrial processes, offering unparalleled precision, versatility, and durability.
The PMD75 offers an impressively broad measurement range, capable of handling differential pressures from extremely low values up to relatively high pressures. It can accurately measure differential pressures as low as a few pascals, making it ideal for applications that demand high - sensitivity, such as in cleanroom environments where minute pressure differences can affect air quality and process integrity. On the other end of the spectrum, it can measure up to several hundred kilopascals, catering to more industrial - strength applications like in large - scale chemical reactors or high - pressure pipelines. This wide - ranging capability allows the PMD75 to be used across diverse industries, from the delicate operations in the pharmaceutical sector to the heavy - duty processes in the oil and gas industry.After signal conditioning and compensation, the PMD75 can transmit the processed signal in multiple ways. It supports standard analog output, typically a 4 - 20 mA current loop, which is widely used in industrial control systems. This analog signal can be easily transmitted over long distances through electrical cables.
Features
The PMD75 is highly versatile in the types of differential pressure it can measure. It can handle differential pressure measurements in liquids, gases, and steam, adapting seamlessly to different process media. For example, in a water treatment plant, it can measure the differential pressure across filters to determine when they need cleaning or replacement. In a petrochemical refinery, it can monitor the differential pressure in pipelines to detect blockages or changes in flow characteristics. Whether it's the pressure difference across an orifice plate for flow measurement or the differential pressure in a heat exchanger for performance monitoring, the PMD75 provides accurate and reliable data.
Product Overview
The E+H PMD75 utilizes state - of - the - art sensor technology to achieve its high - precision differential pressure measurements. It commonly employs a capacitive sensing principle. Inside the transmitter, there are two capacitor plates, with one plate being fixed and the other a flexible diaphragm. When differential pressure is applied, the diaphragm deforms. This deformation changes the distance between the two capacitor plates, and according to the principles of capacitance, a change in the distance results in a corresponding change in capacitance. This change in capacitance is then converted into an electrical signal, which is proportional to the measured differential pressure.
The capacitive sensor technology offers several distinct advantages. It provides high sensitivity, allowing the PMD75 to detect even the slightest changes in differential pressure. Additionally, it has excellent long - term stability, reducing the need for frequent recalibration. The sensor is also designed to withstand harsh environmental conditions, including extreme temperatures and vibrations, ensuring consistent performance in demanding industrial settings.
Once the change in capacitance is detected by the sensor, it undergoes a series of signal conversion processes. First, the small electrical signals related to the capacitance change are amplified to a level that can be easily processed. Then, the signals are conditioned to eliminate any noise or interference that may have been introduced during the measurement process.
The PMD75 also incorporates advanced temperature compensation algorithms. Since temperature can affect the performance of the sensor and the overall measurement accuracy, the temperature compensation circuit continuously monitors the ambient temperature and adjusts the signal accordingly. This ensures that the measured differential pressure values remain accurate regardless of temperature fluctuations.
