Publish Time: 2024-08-09
With the development of industrial technology, sensor technology is widely used in various fields. Today, we will focus on a new type of piezoelectric pressure sensor, and discuss its unique performance parameters, characteristics and applications in pipeline pressure, speed and liquid injection monitoring.
Detailed explanation of performance parameters
This piezoelectric pressure sensor excels in several key performance parameters. First of all, its measuring range reaches 100 MPa, which meets the demand for high pressure measurement in the industrial field. In terms of output characteristics, its D33 piezoelectric constant is stable at 380 ± 5% pC/N, which has been certified to ensure the accuracy and reliability of measurement. It is worth noting that the speed of the sensor reaches 750 rpm, indicating that it also has excellent performance in dynamic measurement.
In addition, the pipe diameter specification of the sensor can be adjusted from φ6 to φ10. This flexibility enables it to adapt to pipes with different diameters, greatly broadening the application scenarios. In terms of electrical parameters, the capacitance of the sensor is 2700 ± 10% PF, which is also certified to ensure the stability and consistency of the circuit design.
Analysis of unique features
Adjustable pipe diameter: This design feature allows the sensor to easily adapt to pipes of different sizes without replacing the entire sensor, reducing the cost of use and the difficulty of maintenance.
High sensitivity: Piezoelectric sensors are known for their high sensitivity, which can accurately capture small pressure changes and provide accurate data support for industrial process control.
Special clamp design: In order to facilitate field installation, the sensor adopts a specially designed clamp, which simplifies the installation process and improves the work efficiency.
Discussion on application scenarios
Pipeline pressure monitoring: In the chemical, petroleum, natural gas and other industries, the stability of pipeline pressure is very important. This piezoelectric pressure sensor can monitor the pressure change in the pipeline in real time to ensure the safety of production.
Rotational speed measurement: Although the main function of the sensor is to measure pressure, its high sensitivity and stability also enable it to be applied to rotational speed measurement. For example, in mechanical equipment, the rotational speed can be estimated by measuring the vibration frequency of a bearing or gear.
Injection volume control: In the pharmaceutical, food and other industries, accurate control of injection volume is the key to ensure product quality. Sensors can indirectly reflect the change of liquid injection by monitoring the pressure change in the pipeline, so as to achieve precise control.
Environmental adaptability
The working temperature range of the sensor is from -45 ℃ to 80 ℃, covering most industrial application environments. This shows that the sensor can work stably in extremely cold or high temperature conditions, and ensure the measurement accuracy and reliability in a variety of harsh environments.
To sum up, this piezoelectric pressure sensor has a wide application prospect in pipeline pressure, speed and liquid injection monitoring because of its high sensitivity, adjustable pipe diameter, special clamp design and wide working temperature range. With the deepening of industrial automation and the improvement of intelligent level, the sensor is expected to play an important role in more fields and promote the progress and development of industrial monitoring technology.
