Be cautious for electrical safety, and even it operates at a low voltage, any electrical shock might lead to some unexpected damages. The gas to be measured should be clean and free of particles, as even light particles may be accumulated inside the tiny pressure port that may result in inaccuracy in metrology, clogging, or other irrecoverable damage. Do not apply for any unknown or non‐specified gases that may damage the product. www.Siargo.com FSP2000 User Manual 3 ...

Page 5: Overview
The designed combination of the differential and gauge pressure sensing capability in a small footprint is for the sensing and control in a CPAP (continuous positive airway pressure) equipment that is trending for the miniaturization, where the differential pressure sensing is used for the flow measurement while the gauge pressure provides the necessary feedback for the system. This package allows the CPAP maker to save the space and cost for the required sensing data. While the current packages are best for medical and consumer applications, the manufacturer also offers alternative customized packages. Please contact the manufacturer for additional information. www.Siargo.com FSP2000 User Manual 5 ... -
Page 6: Receipt / Unpack Of The Products
Please check immediately for the integrity of the product and the power and data cable; if any abnormality is identified, please notify the distributor/sales representative or manufacturer as soon as you can. If any defects are confirmed, an exchange shall be arranged immediately via the original sales channel. This user manual shall also be included in the packing box or via an online link for an electronic version which should be sent by your sales agent. In most cases, this manual shall be made available to the customer before the actual order. Please note that the sensor has a pinout that is designed to be directly placed onto a printed circuitry board. Therefore, the power and data cable is an option that will not come with the order automatically. www.Siargo.com FSP2000 User Manual 6 ... -

3.2 Power and data pinout description Table 3.2: FSP6000 pin assignment. PIN DEFINITION 1 SDA, I C data 2 GND, ground 3 VCC, power supply (3.0~5.5 Vdc) 4 SCL, I C clock FSP2000 electrical interface has 4 pins providing I C digital data with a 3.0~5.5 Vdc power supply. The pins can be directly soldered onto a control printed circuitry board (PCB) or via a data cable, which can be ordered from the manufacturer or made by the user. The sensor runs with a minimal current source of 10 mA. A slightly higher current will ensure the proper operation. www.Siargo.com FSP2000 User Manual 7 ... -

Page 13: Technical Notes For The Product Performance
8.2 Precautions for the best performance of the product 8.2.1 Particle contamination It is critical to have the measured gas free of particle contamination. Since the data ports for both the gauge pressure and differential pressure is small, any particle's presence may create a deformed channel leading to large measurement errors. The particle deposition may also clog the channel, creating unstable data output and other instability, resulting in unpredictable measurement circumstances. 8.2.2 Altitude changes Unlike some other products on market, the design of the sensor has a built‐in pressure balancer that preventing membrane deformation due to altitude changes. Therefore, the sensor is intrinsically insensitive to the altitude change‐induced errors. 8.2.3 Excessive humidity or condensation The humidity change will not alter the performance of the sensor. However, if excessive humidity is present resulting in condensation, the measurement port or channel could be blocked or altered. This would result in a very unreliable data output. Please filter or other tools to prevent this situation to occur when using this product. www.Siargo.com FSP2000 User Manual 13 ... -
