HK-2000G Integrated Pulse Sensor

HK-2000G piezoresistive pulse sensor can generated voltage output signal which is proportional to the input pressure, with excellent repeatability and time stability.
The product is very compact, and very suitable for pulse rate detection, non-invasive Cardiovascular Function Testing, detection in Hypertensive syndrome of pregnancy, TCM pulse diagnosis, and so on.
Features
  • Analog voltage signal output
  • Highly integrated, small form
  • High reliability, long service life
  • High sensitivity
