Remote Sensor System Pre-Amp circuit
Remote sensor might cause a trouble if it’s a passive type, has very low power output, and should be connected with relatively long cables. By supplying a current or voltage source through its connection wire, it’s possible to make long enough wiring without suffering much noise/interference. The following schematic diagram show a circuit consist of LM10 to make a remote vibration sensor connection works fine. We don’t need a separate wires for signal and power supply, we send them on the same cable pair! Here is the schematic diagram of the circuit:
