Amplified Sensor (Analog) Integration
In order to meet the higher requirements for signal accuracy and dynamic response in nebulizers, an amplified sensor (analog) has been introduced into the system. This module amplifies the signal after the initial weak signal is collected by the sensor and has the following advantages:
Signal Amplification and Filtering
Amplification Sensor (Analog) pre-amplifies the low-amplitude signals from the MEMS chip, and at the same time cooperates with the filtering circuitry to suppress the noise and ensure the stability and accuracy of the data during the subsequent digital conversion.
Temperature Compensation Consistency
Working in conjunction with the internal ASIC compensation algorithm, the amplifier (analog) module ensures that the amplification process does not introduce additional temperature drift errors, so that the output signal always maintains a high degree of linearity and temperature stability.
Standard Voltage Output
The amplified signal is precision-conditioned and output as a standard voltage, providing accurate pressure data for the nebulizer control system and helping to achieve real-time atomization adjustment.
Easy to integrate
The amplification (analog) module uses printed circuit board (PCB) mounting for small size and low power consumption, allowing it to be seamlessly embedded into compact nebulizer designs while efficiently matching the microcontroller and ADC module.
Technology Principles and Compensation Mechanisms
The heart of a pressure sensor is its digital compensation technology. The integrated ASIC chip utilizes internal algorithms to digitally correct the MEMS pressure sensitive element’s intrinsic offset, sensitivity change, temperature drift, and nonlinear error in real time. Using the supply voltage as a reference, the sensor outputs a set of tightly calibrated and temperature-compensated voltage signals, providing reliable and accurate data to support the atomizer control system.
This design not only improves system response speed, but also effectively reduces errors due to ambient temperature changes and fluctuations in operating conditions, providing robust technology for demanding atomization applications.
Advantages of application in nebulizer
1. Precise control of atomization pressure
In nebulizers, gas pressure directly affects the atomization effect. Through the standard voltage signal output from this sensor, the system can monitor and adjust the internal pressure in real time to ensure that the atomized particles are uniform and fine, thus improving the quality of the spray and work efficiency.
2. Wide measurement range
Whether it is a small atomization unit in a low-pressure environment or a large-scale atomization system requiring high-pressure output, the sensor covers a measurement range of -100 ~ 350 kPa to 1000 kPa can meet the design requirements, providing flexible options for a variety of application scenarios.
3. Compact and Highly Integrated
The SOP6 package makes the sensor extremely small, making it easy to fit into the tight spaces of nebulizers. At the same time, the anti-degassing nozzle design ensures that no accidental dislodgement occurs during vibration or long-term operation, ensuring the long-term stability of the system.
4. Low Power Consumption and System Compatibility
The 3.3~5.5V operating voltage design adapts to the needs of modern low-power atomization systems, and with standard or proportional voltage outputs, it is easy to interface seamlessly with microcontrollers and data acquisition modules.
Application Practice and Design Considerations
Environmental Suitability:
Ensure that the gas medium in the nebulizer is a non-corrosive gas to avoid damage to the sensor. If the temperature of the application environment varies greatly, we need to pay attention to the effect of temperature compensation.
