    Inductive proximity sensor / tachometer

    The sensor is just an inductor that is already made, I can't change its value or parameters, it measures around 900-1000 uH micro henries with LCR meter. I am exciting this coil with a square wave 0 to 5 volts at 60khz to detect the turbine blades. I have to be able to detect the blades and...

    Role of Pull up in reducing noise in a hall effect sensor.

    What decides the choice of value of pull up resistors in hall effect sensors? I have flow sensing system with a hall effect sensor. I was facing some erratic behavior when trying to take out known volume from this sensor. Sometimes it would give out the desired volume in a particular pulse...

    Hi All, not sure if this should be in the test or the sensor section, apologies if I have mistakenly placed it here. I am currently trying to calibrate this Pressure Sensor (...
