Magnetic Pickup Signal Conditioner – 4 Channels
Dycor's Magnetic Pickup Signal Conditioner is a multi-channel signal conditioner for use with up to 4 magnetic pickup sensors in rough industrial environments. It specializes in reading low amplitude signals, processing the data, and then converting the data and providing a distinct 0 to 5 V TTL waveform signal output, with recognizable peaks and troughs. The TTL waveform can, in most cases, connect directly to field instrumentation for further control and monitoring.
How Magnetic Pickup Sensors Work
Magnetic pick-up sensors sense a sudden change in a magnetic field of a passing target (close proximity), without any physical contact. They are able to function well in harsh and extreme conditions and are used in a variety of industrial applications to measure speed, counting, or position sensing, with primary targets being slotted wheels, sprockets and gears, and bolt heads. A magnetic pickup sensor may also be known as a magnetic speed pick up, a magnetic proximity switch, or a Hall effect sensor. The raw signal generated by the sensors is very miniscule in amplitude and can easily be mistaken for noise.
