SPECTEC's DIGISPEC RF pickup, or digital proximity sensor, is a modulated carrier RF sensor coupled with an analog to digital signal conditioner in one compact unit. RF speed pickups are perfect for low flow applications and situations that call for no magnetic drag on the target.
These digital RF flow meter sensors produce a digital frequency output directly proportional to the speed of the actuator (gear wheel or flow meter rotor).
Due to its zero magnetic drag on a ferrous target, the digital RF pickup is extremely useful on very sensitive mechanisms which would be negatively affected by a magnetic field. The internal amplifier provides a constant pulse shaping, signal amplitude, logic-level output, improved signal-to-noise ratio, and an air gap up to 0.25” between the sensor and actuator.
