SP Series Differential Pressure Sensors for Spirometry Applications

Superior Sensor's SP series differential pressure sensors for spirometry applications combine an advanced piezoresistive sensing element with integrated amplification, ADC, DSP, and processor intelligence to greatly simplify customer integration efforts. The SP series leverages floating-point technology to provide a highly precise digital output. When combined with the enhanced zero point and positional immunity, this precision enables the ultimate in spirometry system sensing performance. The SP series optimizes performance, reliability, and system cost for the challenging spirometry market.

The SP series devices include a proprietary Z-Track™ feature which virtually eliminates zero errors. Power-on time is also a consideration and with Z-Track, warm-up time is greatly reduced, making the SP series an excellent choice for time-critical installation applications.

These spirometry devices function flawlessly in crowded RF environments created by a confluence of wireless transmitters. This RF immunity requirement drives the need for special design effort to be put into the product packaging. This is done to minimize the effects of spurious RF signals on the sensor module performance. The SP series has undergone proprietary design techniques to enhance the EMI immunity, reducing the influence of close proximity EMI producing devices such as Wi-Fi, Bluetooth®, and other cellular communication protocols.
