The Electro-Sensors SA420 Signal Conditioner is a complete system which provides an analog signal directly proportional to the speed of a monitored shaft. The 0-10 Vdc and 4-20 mA outputs can be sent to a chart recorder, digital display, PLC, loop controller, drive speed controller, or any other control or monitoring device. The wide voltage range and wave shape flexibility of the SA420 input circuitry allow it to translate signals from Hall Effect Sensors, proximity switches, magnetic sensors, and a wide variety of other pulse generators, into analog outputs.
