Product DescriptionProduct DescriptionE+H PMC51The heart of the PMC51 is its capacitive, oil - free ceramic measuring cell. This advanced sensor technology is based on a ceramic membrane (Ceraphire), which is made of 99.9% AI2O3. The use of ceramic in the sensor construction offers several advantages. Firstly, it provides excellent chemical resistance, making the PMC51 suitable for use with a wide variety of media, including corrosive and abrasive substances. Secondly, the ceramic sensor is highly stable over time, ensuring accurate and consistent measurements even in harsh operating conditions. The sensor's capacitive principle works by measuring the change in capacitance between two electrodes separated by the ceramic membrane. When pressure is applied to the membrane, it deforms slightly, causing a change in the capacitance value, which is then accurately measured and converted into a pressure reading.The PMC51 is designed with a vacuum - proof ceramic membrane. This feature is crucial in applications where the process may involve vacuum conditions, such as in certain chemical reactions, distillation processes, or in the food and beverage industry during vacuum packaging operations. The vacuum - proof design ensures the integrity of the measurement system, preventing any potential damage to the sensor due to vacuum - related stress. Additionally, the membrane has integrated breakage detection, which further enhances the safety and reliability of the transmitter. In the event of a membrane failure, the breakage detection mechanism will trigger an alarm, allowing for prompt maintenance and preventing any potential process disruptions or safety hazards.1. Key Features1.1 High Measurement AccuracyThe PMC51 is renowned for its high measurement accuracy. The standard version of the transmitter offers an accuracy of ±0.15%, while the "Platinum version" provides an even more impressive accuracy of ±0.075%. This high level of accuracy is essential in applications where precise pressure control is critical, such as in chemical reactors, where small variations in pressure can significantly affect the reaction rate and product quality. In the oil and gas industry, accurate pressure measurement is crucial for optimizing production processes, ensuring the safe operation of pipelines and storage tanks, and for accurate inventory management. The high accuracy of the PMC51 also reduces the need for frequent calibration, saving both time and resources in maintenance operations.1.2 Wide Pressure and Temperature RangesThe transmitter supports a wide pressure measuring range, from +100 mbar to +40 bar (+1.5 to +600 psi). This broad range makes it suitable for a diverse range of applications, from low - pressure applications in laboratories or pneumatic control systems to high - pressure applications in industrial processes such as oil refineries, power plants, and hydraulic systems. The PMC51 can also operate in a wide temperature range, from - 40 °C to +130 °C (- 40 to +266 °F), with the ability to withstand a temperature of 150 °C (302 °F) for up to 1 hour. This temperature range flexibility allows the transmitter to be used in various environmental conditions, whether it's in cold storage facilities or in high - temperature process areas.1.3 Multiple Communication ProtocolsThe PMC51 is equipped with multiple communication protocols, including 4 - 20 mA HART, PROFIBUS PA, and FOUNDATION Fieldbus. The 4 - 20 mA HART protocol is one of the most widely used in the industrial world. It provides a reliable analog signal for basic process control, while the HART (Highway Addressable Remote Transducer) protocol allows for digital communication, enabling remote configuration, calibration, and diagnostic functions. PROFIBUS PA is a fieldbus standard that is commonly used in process automation. It offers high - speed data transfer, enhanced diagnostic capabilities, and the ability to network multiple devices together. 2. Technical Specifications2.1 Measurement AccuracyStandard Version: ±0.15%Platinum Version: ±0.075%These accuracy levels are achieved through the use of high - quality components, advanced sensor technology, and rigorous calibration procedures. The high accuracy of the PMC51 ensures that the measured pressure values are reliable and can be used with confidence in critical industrial processes.2.2 Pressure RangeThe pressure measurement range of the PMC51 spans from +100 mbar to +40 bar (+1.5 to +600 psi). This wide range makes it suitable for a broad spectrum of industrial applications. The minimum measurable pressure of 100 mbar allows for accurate measurement in low - pressure systems, such as those found in pneumatic control valves or in some laboratory equipment. Operating Temperature: - 40 °C to +130 °C (- 40 to +266 °F)Short - Term Over - Temperature: 150 °C (302 °F) for 1 hourThe wide operating temperature range of the PMC51 enables its use in various environmental conditions. In cold storage facilities, where temperatures can drop well below freezing, the transmitter can accurately measure pressure without any performance degradation. In high - temperature industrial processes, such as in furnaces or in some chemical reactions, the PMC51 can withstand the elevated temperatures for short periods, ensuring continuous operation and reliable pressure measurement.2.4Repeatability and Long - Term StabilityThe transmitter offers excellent repeatability and long - term stability. The repeatability is typically within ±0.05% of the measured value, meaning that when the same pressure is applied multiple times, the PMC51 will provide consistent readings within this tolerance. The long - term stability is also impressive, with a drift of less than 0.1% URL (Upper Range Limit) per year. This long - term stability is crucial in applications where continuous and accurate pressure monitoring is required over an extended period. For example, in a power plant, where the pressure of steam in boilers needs to be monitored continuously for optimal operation and safety, the long - term stability of the PMC51 ensures that the readings remain accurate over time, reducing the need for frequent calibration and maintenance.SpecificationAccuracy±0.1% FS (optional ±0.075%)Long-term Drift<0.1% FS/yearPressure Ranges100mbar...400barProcess Temperature-40...125°C (optional 150°C)Electrical ProtectionIP67, NEMA 4XExplosion ProofATEX, IECEx, FM, CSACritical service12 monthsCertificationsSIL2 (IEC 61508),3-A, EHEDG,DNV-GL, ABSCompany Profileabout usMain productKeRui (WeiFang) Automation Equipment Co., Ltd. is specialized in industrialautomation instrument development, production and sales, technical servicesand supporting equipment supply of specialized companies.
