Product DescriptionProduct DescriptionABBe 264DSB Differential Pressure TransmitterIn the complex and highly - integrated realm of modern industrial automation, differential pressure transmitters play a pivotal role, serving as the linchpins that ensure the smooth operation and optimization of numerous industrial processes. These devices are responsible for accurately measuring the difference in pressure between two points in a system, which is then converted into a proportional electrical signal for further processing and analysis.In the oil and gas industry, for instance, differential pressure transmitters are essential for monitoring the flow rate of crude oil through pipelines. By measuring the pressure drop across an orifice plate or a Venturi tube installed in the pipeline, the transmitter can precisely calculate the volume of oil flowing per unit time. This information is crucial for efficient production management, as it enables operators to control the flow rate, detect leaks or blockages in the pipeline promptly, and ensure the overall integrity of the transportation system. In refineries, differential pressure transmitters are used to monitor the pressure differences across distillation columns, which helps in maintaining the proper separation of different hydrocarbon fractions and optimizing the refining process.1. Working Principle of ABBe 264DSBThe fundamental principle of differential pressure measurement is deeply rooted in the laws of fluid mechanics, with the Bernoulli equation playing a crucial role. The Bernoulli equation, which is derived from the principle of conservation of energy for an ideal fluid (inviscid and incompressible) flowing steadily along a streamline, is expressed as P+21ρv2+ρgh=constant. Here, Prepresents the pressure of the fluid, ρ is the density of the fluid, v is the velocity of the fluid, h is the height of the fluid above a reference level, and g is the acceleration due to gravity.In the context of differential pressure measurement for flow - rate determination, consider a fluid flowing through a pipe with a constriction, such as an orifice plate or a Venturi tube. As the fluid passes through the constricted section, according to the principle of continuity (A1v1=A2v2, where A is the cross - sectional area of the pipe and v is the fluid velocity), the velocity of the fluid increases at the constriction (A2<A1, so v2>v1). From the Bernoulli equation, when the velocity vincreases, the pressure Pmust decrease to keep the sum P+21 ρv2+ρgh constant. This results in a pressure difference (ΔP) between the upstream and downstream sides of the constriction.Mathematically, the relationship between the pressure difference, ΔP=P1?P2 and the flow rate Q(volume flow rate) can be derived. For an orifice plate, the volume flow rate Q is given by the formula Q=CA2ρ(1?β4)2ΔP, where C is the discharge coefficient, A2is the area of the orifice, and β=Dd is the ratio of the orifice diameter d to the pipe diameter D. This shows that by measuring the differential pressure ΔP across the constriction, the flow rate of the fluid can be calculated, provided that the other parameters (C,A2,ρ,β) are known.Differential pressure can also be used to measure (liquid level). Consider a container filled with a liquid of density ρ. If we measure the pressure at the bottom of the container (Pbottom) and at a reference point above the liquid surface Preference,which is usually the atmospheric pressure Patmif the container is open to the air), the pressure difference ΔP=Pbottom?Preference. According to the hydrostatic pressure formula P=P0+ρgh, where P0 is the pressure at the reference level and h is the height of the liquid column, we can calculate the height of the liquid level h=ρgΔP.2.Technical Specifications2.1 Measurement RangeThe ABBe 264DSB differential pressure transmitter offers a wide and versatile measurement range, catering to a diverse array of industrial applications. Its measurement range typically spans from extremely low differential pressures to relatively high values. For instance, it can measure differential pressures as low as 0 - 0.25 kPa, making it highly suitable for applications that require the detection of very small pressure differences. In applications such as monitoring the air - flow in ventilation systems of cleanrooms, where the pressure differences between different zones are often in the low - kPa range, the ABBe 264DSB can accurately detect and measure these subtle changes.On the other end of the spectrum, it can handle differential pressures up to 40 MPa. This high - end capacity is invaluable in industries like oil and gas extraction and processing. In high - pressure pipelines used for transporting crude oil or natural gas, significant pressure drops can occur across various components such as valves, filters, and flow - measurement devices. The ability of the ABBe 264DSB to measure such high differential pressures ensures that operators can closely monitor the performance of these pipelines and associated equipment. For example, in a large - diameter oil pipeline with a high - flow rate, the pressure drop across a critical valve may reach several MPa, and the 264DSB can precisely measure this difference, providing crucial data for pipeline integrity management and flow - rate optimization.2.2 Accuracy and PrecisionThe ABBe 264DSB differential pressure transmitter boasts an impressive basic accuracy of ±0.075%. This high - level accuracy is a testament to ABBe's advanced manufacturing and calibration techniques.In the precision chemical industry, for example, many chemical reactions are highly sensitive to pressure variations. A slight deviation in pressure measurement can lead to incorrect reaction rates, product impurities, or even safety hazards. The high accuracy of the ABBe 264DSB ensures that chemical engineers can precisely control the pressure conditions in reactors, distillation columns, and other process equipment.SpecificationPower Supply10.5 to 45 V DCProcess temperature-40 ~ 120°C (-40 ~ 248°F)Storage Temperature-50 ~ 85°C (-58 ~ 185°F)Protection LevelIP65Explosion-proof certificationATEX ,IECEx ,FM / FMc ,CSAWeight2kgStandard1/2" NPT, 1/4" NPT, G1/2", M20 x 1.5Flange MountANSI, DIN, JIS standards in various pressure ratingsCompany 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.
