Working Principle And Application Of The Differential Pressure Transmitter
The explosion proof differential pressure transmitter is a typical self-balancing detection instrument. The dp pressure transmitter uses the working principle of negative feedback to overcome the influence of unfavorable factors such as component materials and processing techniques. The differential pressure transducer has greatly improved the traditional throttling device. The dp transmitter has the distinctive feature of balanced rectification. The dp pressure transmitters are widely used in petroleum, chemical industry, metallurgy, electric power, natural gas, water treatment, and other industries. The explosion proof differential pressure transmitters play an important role in closed containers.
The main working principle of the differential pressure transducer is based on the basic principle of hydrostatic pressure. In a closed container, the change value of the liquid static pressure (P) is linearly related to the change value of the liquid level (L), that is, ΔP = KLL (ΔP: change value of the static pressure of the liquid; K: constant; L: change value of the liquid level ). Based on this principle, the dp pressure transmitter can accurately measure the change in liquid level by measuring the change in the static pressure of the liquid in the closed container.
Differential pressure transducers have a wide range of use scenarios in applications. First, in the petrochemical industry, dp transmitters can measure the liquid level of various towers, tanks, tanks, spherical vessels, boilers, and other equipment. Secondly, in the power industry, dp transmitters can measure the liquid level of steam drums, deaerators, and water tanks. In addition, in the metallurgical industry, the differential pressure transmitters are often used to measure the liquid levels of mortar and other slurries in blast furnaces and continuous casting water dust and ash removal systems. At the same time, in the natural gas and water conservancy industries, dp pressure transmitters can measure the liquid flow in pipelines and the water levels in water treatment equipment.
In general, the dp transmitter is a critical industrial automation instrument. Dp transmittercan accurately measure parameters such as liquid level, flow, and pressure. dp transmitters play an important role in various industrial application scenarios.
