Double-flange differential pressure transmitters, as a fluid measurement and control device, are widely used in industrial fields.
It accurately measures the pressure difference in the fluid medium and converts it into an output signal to control, monitor and adjust the operating state of the system.
The following is an in-depth analysis of the working principle, application areas and advantages of double flange differential pressure transmitters.
1. Working principle: The double flange differential pressure transmitter is to convert it into an electrical signal output by sensing the difference in the pressure of the medium on both sides.
It consists mainly of a sensor, a converter, and a circuit board.
1.Sensor: The core component of a double flange differential pressure transmitter is the sensor.
There are two isolated chambers in the sensor, one connected to the measuring medium.
When the pressure in the medium changes, the strain gauges inside the sensor are deformed by the force, which changes the resistance of the sensor.
2.Converter: The resistance change signal output by the sensor needs to be amplified, filtered, and linearized by the converter so that it is proportional to the actual medium pressure change.
3.Circuit board: The circuit board is the control center of the double-flange differential pressure transmitter, which is responsible for receiving the electrical signals processed by the converter and transmitting them to the control system through cables.
2. Application field: Double flange differential pressure transmitter is widely used in various industrial fields, and the following are several common application scenarios: 1Petrochemical: In petrochemical processes, double-flange differential pressure transmitters are used to measure pressure differences in fluid media to control flow, monitor pipeline blockages, detect leaks, etc.
2.Power engineering: In power engineering, double flange differential pressure transmitters are used to measure the pressure difference in the boiler to ensure the normal operation of the boiler and improve the thermal efficiency.
3.Automatic control: Double flange differential pressure transmitter plays an important role in the automatic control system.
It can convert the pressure difference into an electrical signal, which is used to control and adjust the working state of the system, such as automatic process control, liquid level control, etc.
3. Advantages: 1Accuracy: The double-flange differential pressure transmitter has a high-precision measurement capability that accurately reflects the pressure difference in the fluid medium, providing accurate control and monitoring data.
