Industrial Application Solution for X19 Pressure Sensor

The X19 micro-pressure core is a crucial component in pressure sensors and pressure transmitters, designed for small-range, high-performance pressure measurement. Its compact design and ability to be easily amplified and processed make it ideal for industrial applications requiring precise air pressure monitoring. However, its limitations in measuring only clean, non-corrosive gases necessitate careful selection of its use cases. This article explores the industrial applications of the X19 sensor, best practices for installation and use, and key considerations for maintaining optimal performance.

2. Key Features of X19 Sensor

Small-Range High Precision: The X19 sensor is ideal for pressure measurement below 5 kPa, making it suitable for sensitive applications requiring low-pressure monitoring.

Diffused Silicon Technology: The sensor's silicon pressure-sensitive chip is enclosed in a 316L stainless steel shell, ensuring durability and reliability in controlled environments.

O-Ring Pressure Sealing: This design allows for easy installation and integration into various industrial systems.

Customizable Options: X19 can be customized for special needs, including all-welded structures, wide temperature compensation, and high-reliability configurations.

4. Installation and Maintenance Best Practices

4.1. Proper Installation

Ensure that the measuring medium is clean and dry air, with minimal moisture content to prevent inaccuracies.

Avoid sudden exposure to high-pressure changes, such as opening an air valve suddenly, which may permanently damage the sensor.

Install the sensor with O-ring sealing for optimal stability and accuracy.

4.2. Maintenance and Damage Prevention

Regularly check the resistance values between red (+) and blue (-) (2.4kΩ to 3.0kΩ) and between yellow (+) and white (-) (3.8kΩ ± 0.5kΩ).

If air leakage is detected, the silicon layer may be damaged and cannot be repaired.

Dry the sensor if moisture exposure affects measurement accuracy.

Avoid overload pressure beyond the specified range to prevent irreversible damage.

5. Customer Guidance and Quality Assurance

5.1. Customer Support and Troubleshooting

Before installation, provide customers with assembly videos and documentation to ensure proper handling.

Encourage customers to conduct a simple test: turn on power, measure zero point, and check response by blocking the pressure hole.

If installation issues arise, refer customers to the resistance measurement method to determine if the sensor is functional.

5.2. Product Promotion and Expansion

Customers requiring low-pressure gas measurement (200 Pa to 5 kPa) should be introduced to the X19 sensor.

If customers require differential pressure measurement, introduce them to the X19D variant, which offers enhanced measurement capabilities.

Inform customers of moisture-related issues and recommend usage in controlled environments to maintain accuracy.

The X19 micro-pressure sensor is a highly specialized component suited for precision applications in HVAC, medical devices, industrial automation, environmental monitoring, and aerospace. By ensuring proper handling, installation, and maintenance, industries can leverage the X19 sensor’s high accuracy and reliability. With continued advancements and customization options, the X19 sensor stands as a crucial solution for low-pressure measurement needs in modern industrial applications.
