SP Series Differential Pressure Sensors Evaluation Kit Giveaway

In partnership with Superior Sensors

All About Circuits in collaboration with Superior Sensor Technology is giving away a complete evaluation kit for the SP Series of differential pressure sensors. Specifically designed for spirometers and other respiratory applications, the SP Series sensors support up to 4 pressure ranges in one device and provide a highly accurately diagnosis of a patient’s lung function in a shorter period of time. Unique capabilities include:

1. Z-Track™ technology that virtually eliminates errors due to zero drift.

2. Positional sensitivity errors are reduced by up to 10x relative to competing solutions.

3. Selectable bandwidth filter from 25 Hz to 250 Hz.

4. Accuracy within 0.05% of selected range & most stable zero pressure sensing platform. 

The evaluation system consists of an evaluation board plus one unit of each SP Series sensor (3 total sensors). Evaluation Kit connects to a PC via USB interface for configuration and testing (see included documentation). Winner selects evaluation board with either I2C or SPI interface.

Product Features

  • Highly integrated sensor with ADC and DSP
  • Programmable ranges from ±250 Pa to ±40 kPa
  • 16 bit resolution each range
  • Ultra low noise, 19+ bit Effective Resolution
  • Selectable Bandwidth Filter from 25Hz to 250Hz
  • Z‐Track™ virtually eliminates zero drift
  • Very High Accuracy +/‐ 0.1% of Selected Range
  • Long Term Stability +/‐ 0.1% FSS/year
  • Enhanced EMI Immunity
  • Output Update Rate of 500Hz
  • Temperature Compensated 0°C to 50°C
  • Supply Voltage Compensation
  • Standard I2C and SPI Interface

    in order to identify the two different types of abnormal ventilation patterns, obstructive and restrictive I am planning to build the Monitoring and alerting system using this sensor evaluationkit.

    To build a Hoverboard with low cost. Hoverboard became unique due to its lightweight, compact size and pressure steering. It can rotate to 360 degrees just by changing the pressure through your feet.you can change your direction just by changing pressure or center of gravity of body. This will help me make the project a better success and to move further in the industry.
