Introduction
The pressure monitoring device for forming coal is an important component of the coal pressure monitoring system. It is used to monitor the pressure of the forming coal, so it is necessary to have a certain level of precision and reliability. In this paper, a pressure monitoring device for forming coal is designed to achieve accurate and reliable pressure monitoring.
Design principles
The first step in designing the pressure monitoring device for forming coal is to establish design principles. To ensure the accuracy and reliability of the pressure monitoring device, the device must use reliable components with high precision and be resistant to environmental deterioration. In addition, the device must be configured according to the requirements of the pressure monitoring system, so as to adapt to the application environment and meet the measurement accuracy requirements.
Design structure
The pressure monitoring device for forming coal is composed of a number of components such as sensor, amplifier, power supply, digital display device, etc. The sensor is used to detect the pressure of the forming coal. The amplifier is used to convert the signal into a usable digital signal. The power supply is used to supply power to the device. The digital display device is used to display the measured value accurately and clearly.
Sensor selection
The most important component in the pressure monitoring device for forming coal is the sensor. The sensor must have high precision, good stability, and wide dynamic range to meet the requirements of the pressure monitoring system. This paper uses a low-pressure differential sensing element composed of wire and diaphragm. The diaphragm is made of stainless steel, which has good mechanical properties and chemical stability, and is resistant to high pressures and temperatures. The sensor has a high precision, good stability and wide dynamic range, which can meet the requirements of the pressure monitoring system.
Amplifier selection
The amplifier is used to convert the low-level signal detected by the sensor into a usable digital signal. The amplifier must have a stable gain and good noise immunity. It is recommended to use an operational amplifier in this design, because it has low noise, high gain, and low power consumption.
Power supply selection
The power supply is used to provide power to the pressure monitoring device for forming coal. The power supply must have high stability, wide input voltage range and good overload protection performance. This paper uses a switching power supply. It has high efficiency, wide input voltage range, good overload protection performance and high stability, which can meet the requirements of the pressure monitoring device for forming coal.
Digital display device selection
The digital display device is used to display the pressure of the forming coal accurately and clearly. This paper uses a high-precision digital display device, which has high accuracy and long life. The digital display device can accurately display the pressure of the forming coal, which can meet the requirements of the pressure monitoring system.
Testing
To ensure the accuracy of the pressure monitoring device for forming coal, the device needs to be tested. This paper uses a simulator to simulate the environment of formation coal pressure. The pressure of the simulated environment can be accurately determined. The pressure monitoring device for forming coal can be tested in the simulated environment to test the accuracy and reliability of the device.
Conclusion
In this paper, a pressure monitoring device for forming coal is designed, which can accurately and reliably monitor the pressure of the forming coal. The pressure monitoring device is composed of a number of components, such as sensor, amplifier, power supply and digital display device, which have high precision and stability and can meet the requirements of the pressure monitoring system. The designed pressure monitoring device for forming coal is tested in the simulated environment to ensure its accuracy and reliability.
