Digital Sensors from INPROX Sensors
January 25, 2007
INPROX Sensors, Boston, MA, offers its inGen Linear Direct digital sensors that can interface directly with microprocessors without the need for signal conditioning, and use a specially tuned oscillator that produces a frequency of oscillation, a square wave output that is read as a pulse train by microprocessors. Because of the sensors' operating principle, they can perform multifunction sensing, e.g., an InGen position sensor provides a position status update at 25 kHz to 500 kHz. First-, second-, and third-order derivatives of the position information allow you to measure position, acceleration, velocity, and jerk with a single measurement. Different physical quantities can use different bands of working frequencies, creating multiple distributed sensors on a single bus.
