SP Series Differential Pressure Sensors

Evaluation Kit Giveaway

SP Series Evaluation Kit

Giveaway Overview

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.
