Active Speed Sensors - RF Models
Active, or amplified sensors with digital output offer a low-cost solution for interfacing directly to data acquisition systems. These sensors integrate a preamplifier/signal conditioner within the sensor housing and offer the advantages of excellent noise immunity and greater transmission capability.
Input power supply requirements cover the most popular ranges for both commercial and industrial use. The output frequency of these sensors has a square pulse waveform (digital) that directly relates to the number of turbine blades, gear teeth, etc. that have been sensed. These pulses, in turn, can be correlated to determine flow rate, RPM, or velocity.
