SPECTEC'S digital magnetic sensor, or active Variable Reluctance (VR) sensor, is a magnetic speed sensor coupled with an analog to digital signal conditioner in one compact unit. The digital magnetic sensor's solid state internal analog to digital converter creates a digital output signal from the magnetic pickup's analog signal created by the excitation due to a passing target. The digital output from sensing a vehicle's rotating gear or a cotter key slot can be read by counters, meters or governing instrumentation.
DIGISPEC digital magnetic speed sensor's internal amplifier provides a constant logic-level shaped pulse, signal amplitude output, improved signal-to-noise ratio, usability at low and high RPMs and a greater air gap between the sensor and the actuator. An internal temperature probe is available, which is positioned near the center of the face of the sensor for a dual output variation. A variety of probe types and sense positions are available.
SPECTEC digital magnetic speed sensors are found in high pressure installations, in the oil fields and oil terminals around the world, and rugged applications in truck and industrial equipment.
DIGISPEC Digital Magnetic Speed Sensor Applications:
Applications of digital magnetic sensors are in vehicle speed sensors, wheel speed sensors, and tachometers and applications demanding very accurate signal detection. Digital magnetic sensors are also used with targets such as: slotted wheels, sprockets, conveyor belts and bolt heads.
