IntroductionIn industrial automation, pressure transmitters and temperature transmitters are two commonly used instruments for process measurement. Both play vital roles in ensuring the accuracy of operations, but pressure transmitters are particularly susceptible to zero drift, a phenomenon that leads to measurement errors over time. On the other hand, temperature transmitters experience this issue much less

Differential pressure (DP) flow meters are widely used to measure the flow rate of fluids, including gases, liquids, and steam, in pipelines. The basic operating principle behind these devices is that as a fluid flows through a constriction, the pressure drops in proportion to the square of the flow velocity. This pressure difference is then

To effectively prevent and significantly reduce the risk of hazardous chemical accidents, safety instrumented systems (SIS) equipped with lifecycle management functions are required for new projects and operational facilities, such as installations, tanks, and more. These systems undergo a professional evaluation of their Safety Integrity Level (SIL). The interlock control logic, being the core component

Introduction The application of differential pressure transmitters in flow measurement not only reflects their technical maturity and reliability but also demonstrates their indispensable role across various industries. This article delves into the working principles, calculation methods, structural components, and diverse applications of differential pressure transmitters, offering a comprehensive understanding of their utility in industrial processes.

Pressure sensors are generally composed of metal structural components and electrical circuits. Some transmitters are also equipped with display panels or are used in conjunction with digital indicators. Users typically perform basic maintenance on these transmitters, such as checking electrical connections, cleaning the transmitter, replacing seals, changing terminal blocks, and adjusting zero points and ranges.

Introduction In industrial measurement and automation, pressure transmitters play a crucial role in ensuring accurate and reliable readings. However, noise interference is one of the primary factors that can degrade their measurement accuracy. Noise in pressure transmitters can be broadly categorized into internal noise and external noise. Internal noise is further classified into thermal noise

Pressure transmitters play a crucial role in monitoring and controlling pressure in industries such as chemicals, power generation, and oil and gas. However, in outdoor or humid environments, water ingress can damage the equipment and even lead to safety incidents. In line with chemical instrumentation standards, the rain and waterproofing measures for pressure transmitters must

Causes and Solutions Pressure measurement is a crucial parameter in petrochemical production, with various measurement methods available. Among them, pressure transmitters are widely used for direct pressure measurement, while differential pressure transmitters are employed for measuring pressure differences. However, in real-world applications, incorrect readings or abnormal fluctuations in pressure and differential pressure transmitters are common

Dual flange capillary tubes play a crucial role in pressure measurement, temperature monitoring, and other process automation systems across industries such as petrochemical, chemical, metallurgy, and more. Proper selection, installation, and maintenance are essential to ensuring the stability of instrument performance, measurement accuracy, and the longevity of the equipment.
