The integrated circuit also includes a band-gap RPM sensing in exercise and rehabilitation equipment regulator and a digital output in response to very low magnetic Magnetic interrupt in exercise and rehabilitation equipment fields. Absence/presence detection in infusion pumps These sensor ICs may be operated with either a North or a Position sensing of medication dispensing cabinet drawers South magnetic pole applied in parallel to the sensor IC. The Incline position sensing in hospital beds polarity does not need to be identified, simplifying installation in White goods single pole applications and doubling the resolution in rotating Lid, door and drawer position detection magnet applications. Fluid flow detection These small and highly sensitive omnipolar devices have Liquid level detection become a popular building block for flow metering, motor RPM and cylinder position sensing.
