(3) Digi-Prox® Sensor have been specifically developed for turbine flow meter applications where the users requires a "no drag" operating characteristic. Special self compensating circuit technology has been utilized to provide long-term stability. These units have a wide supply voltage range to 24 VDC.The sensors are also protected against reverse voltage, overvoltage and supply surges. These sensors should cover the requirement of almost all applications. These units can also be used in gear sensing applications.
