Product Description Product DescriptionIn the realm of industrial instrumentation, the 3051CD Pressure Transmitter paired with a Five - valve assembly stands out as a highly sophisticated and reliable solution for pressure measurement applications. Engineered by Emerson, a globally recognized leader in automation and measurement technologies, this device has been designed to meet the diverse and demanding requirements of various industries, ranging from oil and gas to chemical processing, power generation, and beyond. This detailed exploration will cover its design features, operational principles, technical specifications, applications, and the advantages it offers over competing products in the market.The 3051CD Pressure Transmitter is built with a rugged housing, typically made of high - grade materials such as 316L stainless steel. This choice of material provides excellent resistance to corrosion, making it suitable for use in harsh industrial environments where exposure to chemicals, moisture, or extreme temperatures is common. For example, in petrochemical plants, where aggressive chemicals are handled, the 316L stainless - steel housing ensures the long - term integrity of the transmitter, protecting the delicate internal components from damage.The Five - valve assembly, which is an integral part of the 3051CD setup, is also constructed with durability in mind. The valves are designed to withstand high pressures and frequent operation. They are typically made of materials that can resist wear and tear, ensuring reliable performance over an extended period. The assembly is carefully engineered to provide a secure and leak - tight connection between the transmitter and the process piping, minimizing the risk of pressure leaks and ensuring accurate pressure measurement.FeaturesAt the core of the 3051CD Pressure Transmitter lies an advanced capacitive sensing element. Capacitive sensors work on the principle of detecting changes in capacitance caused by the deformation of a diaphragm under pressure. When pressure is applied to the diaphragm, it deflects, altering the distance between two electrodes. This change in distance results in a corresponding change in capacitance, which is then accurately measured by the transmitter's internal circuitry.The capacitive sensing technology used in the 3051CD offers several advantages. It provides high accuracy, with the ability to detect even minute pressure changes. The sensors are also highly stable, ensuring consistent performance over time. Additionally, they have a fast response time, allowing for real - time monitoring of pressure fluctuations in dynamic industrial processes. Product Overview When pressure is applied to the 3051CD Pressure Transmitter, the process begins with the transfer of this pressure to the sensing diaphragm. In the case of differential pressure measurement (which the 3051CD is well - equipped to handle), the pressure difference between the high - pressure and low - pressure sides of the transmitter causes the diaphragm to deflect. This deflection is then translated into a change in capacitance, as described earlier.The Five - valve assembly plays a crucial role in this process. The isolation valves in the assembly allow for the isolation of the transmitter from the process fluid during maintenance or calibration. This ensures the safety of personnel and the accuracy of the calibration process. The equalizing valve, on the other hand, is used to equalize the pressure on both sides of the diaphragm when the transmitter is being installed or removed, preventing damage to the sensing element.The 3051CD Pressure Transmitter, along with its Five - valve assembly, is designed to be compact and space - saving. This is particularly beneficial in industrial settings where space is often at a premium. The compact design allows for easy installation in tight spaces, such as on crowded pipe racks or in small control panels. Despite its small size, the 3051CD does not compromise on performance, packing a powerful set of features into a relatively small footprint.Product ParametersTypeDifferential Pressure Transmitter Place of OriginChina, SingaporeIngress ProtectionIP67Warranty1 YearSingle Gross Weight5.000 kgCustomized SupportOEM, ODM, OBMBrand NameRosemountModel Number3051CDMaterial316L Stainless SteelsSelling UnitsSingle itemCustomized SupportOEM, ODM, OBMBrand NameRosemountModel Number3051CDMaterialAluminum, SSTWarranty1 yearsOutput4-20mA+HART/FFCalibration0~ 275.79 barMeasurement RangeUp to 2000 psi (137,9 bar) differentialPower Supply10.5~42.4VDCSingle Package Size30X30X30 cmPackaging & ShippingCarton BoxesCompany ProfileKeRui (Weifang) Automation Equipment Co., Ltd.Specializes in industrial automation instrument development, production and sales, technical services, and supporting equipment supply to specialized companies.
