Abstract: A differential pressure transmitter is an instrument used to measure the differential pressure of fluids or gases.
A differential pressure transmitter is an instrument used to measure the differential pressure of a fluid or gas. It converts the difference between the pressure at which a fluid or gas enters and the pressure at which it exits into an electrical signal output, usually a current signal (such as 4-20mA) or a voltage signal (such as 0-10V).
The function of a differential pressure transmitter is to measure, convert, and transmit differential pressure information in a fluid or gas, in order to achieve monitoring, control, and analysis of fluid or gas processes. It is widely used in the industrial field to help improve production efficiency, optimize process control, and ensure the safety and reliability of the system.
Characteristics of differential pressure transmitter
The differential pressure transmitter has the characteristics of high accuracy, wide measurement range, durability, and corresponding fast speed:
1. High precision: Differential pressure transmitters usually have high measurement accuracy and stability, and can provide accurate differential pressure measurement results.
2. Wide measurement range: They can adapt to various pressure difference ranges, ranging from a few millibars to a few hundred bars, and can meet the needs of different applications.
3. Durability: Differential pressure transmitters are usually designed with materials and structures that are resistant to corrosion, high temperature, or pressure to adapt to various harsh working environments.
4. Quick response: They can quickly respond to changes in pressure difference and convert it into electrical signal output for timely monitoring and control of the process.
Application of Differential Pressure Transmitters
1. Industrial process control: used to monitor and control pressure differential changes in industrial processes, such as chemical plants, oil and natural gas production, etc.
2. Liquid level measurement: Determine the liquid level height by measuring the static or dynamic pressure difference of the liquid.
3. Gas flow measurement: Calculate the gas flow rate by measuring the pressure difference of the gas in the pipeline
4. Air conditioning and ventilation system: used to monitor and regulate the air flow and air quality in buildings.
5. Liquid or gas filtration system: used to monitor and control the differential pressure in the filtration system to ensure filtration efficiency and normal operation of the equipment.
