Digital Magnetic Speed Sensors
SPECTEC’S digital magnetic sensor couples a magnetic sensor to digital signal conditioner in one compact unit. This 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.

The digital magnetic sensor’s internal A/D converter creates a digital output signal from the magnetic pickup’s analog signal created by the excitation due to a passing target, such as a vehicle’s rotating gear or a cotter key slot, that can be read by counters, meters or governing instrumentation.

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.
