It can adapt to a variety of different pressure ranges, ranging from a few millibars to hundreds of bars, and can meet the needs of different application scenarios.For example, in oil pipeline transportation, low-pressure product oil is transported, and high-pressure crude oil is transported for a long distance to measure differential pressure.
In the process of long-term use, it can maintain stable measurement performance and is not affected by environmental factors such as temperature, humidity, vibration and so on.This is important for industrial processes that require continuous monitoring and control, ensuring the reliability of the measured data.
Due to the high pressure environment in the industrial production process, the differential pressure transmitter is usually made of high-strength materials, which can withstand large static pressure and maintain stable performance and precise measurement under high pressure.

The differential pressure transmitter usually consists of two pressure interfaces, which are respectively connected to the two ends to be measured.When there is a pressure difference between the two ends, this pressure difference acts on a specific element inside the transmitter.
Based on the principle of force equilibrium, the pressure difference will cause the displacement of the elastic element, which is proportional to the pressure difference.The sensor detects the displacement of the elastic element and converts it into an electrical signal.
The conversion circuit then processes the electrical signal, such as amplification, filtering, etc.Then, a standard current or voltage signal is output, which reflects the pressure difference between the measured two ends and can be used for monitoring and controlling the industrial process.

Differential pressure transmitters play an important role in refineries.It precisely measures the pressure difference of oil products in pipelines and equipment, assists in flow monitoring and control, and ensures the precise measurement of crude oil processing and product oil transportation.In the distillation tower and other devices, the pressure difference at different levels is monitored in real time to provide key data for the optimization of the fractionation process and ensure product quality and production efficiency.
The differential pressure transmitter precisely measures the pressure difference of the liquid medicine in the pipeline and container in the pharmaceutical factory, ensures the stability of the liquid medicine delivery and the precise control of the flow, and ensures the consistency and precision of the drug production process.In the process of filtration and distillation, real-time monitoring of pressure difference changes provides a key basis for process optimization and equipment operation status judgment, and helps to improve the quality of drugs.
Differential pressure transmitter plays an important role in thermal power plant.It precisely measures the pressure difference of steam in pipelines and equipment, realizes the precise monitoring and control of steam flow, and ensures the stable operation of power generation and heat supply.In order to optimize the efficiency of heat exchange and improve the efficiency of energy utilization, the change of pressure difference is monitored in real time in key parts such as heat exchangers in thermal power plants.

In the modern petrochemical plant, the differential pressure transmitter has become the first choice of hydrogenation unit in many petrochemical enterprises because of its good performance and stability.It can precisely measure and display the pressure and differential pressure, help operators to grasp the operation status of the hydrogenation unit in real time, and ensure the safety and efficiency of the production process.
Differential pressure transmitter is widely used in power, chemical and pharmaceutical industries in industrial production, and its precision and reliability are very important.The experimental research on the characteristic curve of differential pressure transmitter under different static pressures and the development of a new type of online detection device for static pressure follower differential pressure transmitter have promoted the development of differential pressure transmitter detection technology.
Differential pressure transmitter plays an important role in the field of urban sewage treatment.It is widely used in all aspects of sewage treatment plants, through precise monitoring of the liquid level difference of reaction tank and sedimentation tank, it provides precise data basis for process control.The sewage treatment process is precise and controllable, which improves the treatment efficiency and water quality, and makes a positive contribution to the improvement of the urban water environment.
