JSPR-A0 High-Precision Silicon Resonant Pressure Sensor
Product Overview
The JSPRA0 is a high-precision pressure sensor that meets the requirements of harsh industrial environments where high accuracy and long-term stability are essential. Thanks to the integrated silicon resonant sensor core, these features are possible. With an overall accuracy of only ±0.02% FS over a wide temperature range and an annual stability of up to ±100 ppm FS, it is a precision pressure measurement solution that you can rely on even in tough environments. Besides that, the onboard state-of-the-art signal processing unit offers a full temperature compensation feature, and user systems can easily connect to standard current, voltage, or digital outputs.

Technical Advantages
● High Accuracy: The sensor can reach an accuracy up to ±0.02% within the entire range of temperature compensation. This is exactly the level of accuracy required for high-precision pressure sensing in calibration systems and process control.
● Fast Dynamic Response: Sensor downtime in pressure change detection is <300 milliseconds after a pressure change.
● Excellent Long-Term Stability: A stability level of ±100 ppm FS/year implies that the sensor requires very few recalibrations, which leads to lower operating costs.
● Superior Overpressure Protection: The sensor is capable of handling a pressure of 1.5 times the full-scale pressure without any harm. This makes it very tough, especially in situations where such characteristics are crucial, for example, in outdoor applications.
● Silicon Resonant Sensor: Compared with the traditional piezoresistive sensors, silicon resonant sensors provide advantages like high-frequency response and low drift, thus are superior to piezoresistive sensors in these aspects.

FAQ
1. Q: What is the main factor of this sensor being able to achieve ±0.02% FS accuracy?
A:The main factor is that it features a silicon resonant sensing core that allows it to have a level of accuracy and excellent stability far beyond that of the traditional piezoresistive or capacitive technologies sensors.
2. Q: What does ±100 ppm FS/year stability mean practically?
A:Such an extraordinary long-term stability is far enough to be combined with the extension of calibration intervals (typically 24-36 months), thus leading to a reduction of maintenance costs and ensuring measurement reliability in critical processes.
3. Q: Where do you need such precision?
A:It can be considered necessary for the calibration standards, test benches, pharmaceutical manufacturing, and precision process control, where the slight pressure variations may still have a great impact on the product quality or system performance.
4. Q: What is the reason the digital outputs (RS485/RS232/CAN) are the preferred ones when it comes to this sensor?
A:The digital interfaces offer
communication that is noise-immune and also the direct network integration, which advantages the sensor's high accuracy preservation without signal degradation even at long distances.
