Description
The WPAS02 plastic package pressure sensor is a well-engineered device that combines high-precision MEMS pressure sensitive chips with reliable production processes. Its standard pin structure simplifies the usage for customers, making it easy to integrate into different systems. This design also enables it to provide a cost-effective plastic sealed pressure sensor solution specifically tailored for OEM clients.
It’s important to note that the WPAS02 series plastic sealed pressure sensors are designed for use with dry and non-corrosive gases only. This limitation defines its application scope, but within this boundary, it performs with high reliability. The ability to customize different ranges and output methods according to customer needs adds to its versatility, allowing it to be adapted to a wide variety of requirements.
- Process Control System: In industrial settings, the WPAS02 can be used to monitor and control pressure in various processes. For example, in manufacturing lines where the pressure of gases used in production needs to be regulated, this sensor can provide accurate data for process optimization.
- Pressure Calibration Instrument: It serves as a reliable reference for calibrating other pressure measurement devices. Its high accuracy of ±0.3%FS makes it suitable for ensuring the precision of pressure calibration instruments.
- Medical Instruments: In the medical field, it can be used in devices such as sphygmomanometers to measure blood pressure. Its performance characteristics, including accuracy and reliability, are crucial for obtaining accurate medical readings.
- Environment Monitoring: For monitoring the pressure of gases in environmental settings, such as in air quality monitoring stations. It can help detect changes in atmospheric pressure or the pressure of specific gases, contributing to environmental research and protection.
- Consumer Product: In consumer products like air pumps or some home appliances that involve gas pressure control, the WPAS02 can be integrated to ensure proper operation.
- Sport Product: In sports equipment such as inflatable sports balls or some high-altitude sports devices that require pressure measurement, this sensor can play an important role.
- Compact Package: The SOP6 package makes it compact and suitable for module assembly, saving space in device designs.
- Wide Temperature Adaptability: With a working temperature range of -20℃ to 80℃ and a storage temperature range of -55℃ to 150℃, it can operate and be stored in a variety of temperature conditions.
- High Accuracy: Achieves an accuracy of ±0.3%FS, providing precise pressure measurements for different applications.
- Low Cost: Offers a cost-effective solution for OEM customers, making it an attractive option for mass production and applications where cost is a consideration.
- High Reliability: With features like low non-linearity, hysteresis, and repeatability, as well as a long lifespan of 10×10⁶ pressure cycles, it ensures reliable performance over time.
- Good Mechanical Resistance: Can withstand mechanical vibration of 20g (20～5000HZ) and an impact of 100g (10ms), making it suitable for applications where mechanical stress may be present.
