Product Description
At the heart of the E+H PMP55 is its advanced pressure - sensing technology. It utilizes a piezoresistive sensor, which operates on the principle that when pressure is applied to the sensor, the process isolation diaphragm deforms. This deformation causes a change in the resistance values of the piezoresistors within the sensor's Wheatstone bridge. The change in resistance is then converted into a proportional voltage signal. This conversion process, based on single - crystal silicon semiconductor technology, is highly accurate and sensitive, allowing for precise pressure measurements even in challenging environments.
The E+H PMP55 is a digital pressure transmitter renowned for its robust and innovative design. It features a fully welded diaphragm seal, which is a key aspect of its construction. This design not only simplifies the installation process but also significantly enhances the device's reliability, especially in extreme operating conditions. The all - welded structure provides a high level of protection, safeguarding the sensor from the harsh external environment.
The choice of materials in the PMP55's construction is also a testament to its quality. For example, the use of 316L stainless steel in many of its components makes it highly resistant to corrosion. This is particularly crucial in industries such as chemical manufacturing, where the transmitter may be exposed to aggressive chemicals. In addition to 316L stainless steel, other materials like Alloy C, tantalum, PTFE, and rhodium - over - gold are used for the process membrane, depending on the specific application requirements. These materials offer excellent chemical resistance and mechanical strength, ensuring the long - term stability and durability of the device.
Features
The PMP55 offers a variety of signal output options to suit different industrial automation systems. It can output a standard 4 - 20 mA analog signal, which is widely used in industrial control systems. In addition to the analog signal, it also supports digital communication protocols such as HART (Highway Addressable Remote Transducer), PROFIBUS PA, and FOUNDATION Fieldbus. The HART protocol enables two - way communication between the transmitter and a host system, allowing for remote configuration, calibration, and diagnostic functions. PROFIBUS PA and FOUNDATION Fieldbus are more advanced digital communication protocols that offer high - speed data transfer, multi - drop capabilities, and enhanced diagnostic features. These protocols are particularly useful in complex industrial processes where real - time data exchange and advanced control strategies are required.
Product Overview
Temperature can have a significant impact on the accuracy of pressure measurements. To address this issue, the E+H PMP55 is equipped with an advanced temperature compensation system. This system continuously monitors the ambient temperature and adjusts the pressure measurement accordingly. By doing so, it ensures that the measured pressure values remain accurate and reliable, regardless of temperature fluctuations. The PMP55 can operate over a wide temperature range, from - 70 °C to + 400 °C (- 94 °F to + 752 °F), making it suitable for applications in extreme cold or hot environments. The temperature compensation mechanism is designed to be highly effective, minimizing the temperature - related errors and providing consistent performance across the entire operating temperature range.
The PMP55 has a wide pressure measurement range, covering from + 400 mbar to + 400 bar (+ 15 to + 6,000 psi). This broad range makes it adaptable to a diverse range of industrial applications, from low - pressure systems in the food and beverage industry to high - pressure processes in the oil and gas and chemical sectors. The ability to measure such a wide range of pressures accurately is a major advantage of the PMP55, as it eliminates the need for multiple transmitters in applications where the pressure may vary significantly.
Accuracy is a critical parameter for any pressure transmitter, and the E+H PMP55 does not disappoint. Standard models of the PMP55 offer an accuracy of ±0.15% of the full - scale range. For applications that demand even higher precision, there is a "Platinum Edition" available, which achieves an impressive accuracy of ±0.075% of the full - scale range. This high level of accuracy ensures that the measured pressure values are extremely close to the true values, enabling precise control and optimization of industrial processes. Whether it is monitoring the pressure in a pharmaceutical reactor or a high - pressure pipeline in an oil refinery, the PMP55's accuracy provides the confidence needed for reliable operation.
