This video tutorial is about the hall effect WSS sensor. This video describes about how the hall effect sensor work. The wheel speed sensor uses the WSS family. Hall effect sensor are three wire sensors with the reference voltage, ground and the signal terminal. The reference voltage can be 5V,7V,8V or 12V. The reference voltage is supplied by the ABS […]

The schematic diagram below show signal conditioning circuit for remote current loop temperature transmitter. This thermocouple temperature transmitter is loop powered, means it doesn’t need its own power supply since the supply is provided by the current loop receiver. Thermocouple is basically a junction of two different metallic material that measures the temperature difference. This thermocouple signal conditioner circuit is […]

Clipping is a condition where a signal is truncated by insufficient processing. The cause of clipping can be different for various case, but most of them, especially in power amplifier stage, is because the amplifier is forced to serve out-range of power when the input volume is too high. Detecting severely clipped signal is easy by listening, but a soft […]

This is a audio-controlled lamp circuit. This circuit requires low voltage input such as pre-amplifiers, tone control, or general audio line level output. It’s also possible to feed the input with signal from small power amplifier output, or high power amplifier witk low volume level. The characteristic of lamp dimming (incandescent lamp) will look like coming from proportional controller since […]

This circuit is two wire light level detector, we don’t separate wires for power this sensor system and for delivering the output signal. With current loop, we do both function in a single pair of cable, just provide the voltage supply and measure the current as the output signal. The core of this circuit is LM10 voltage reference and op-amp […]
Read moreThis is a EGR valve temperature sensor video. This video describe how the EGR valve temperature sensor works. The EGR gasses temperature sensor works like the coolant temperature sensor. The sensor uses the thermistor that has negative temperature Coefficient. That means the resistance decreases with increasing temperature. Here is the tutorial video: The operation of the EGR temperature sensor is […]

The circuit of the milliohm adapter is shown on the following figure. Under test, it can apply 1 A, 100 mA, or 10 mA to the resistance. If your voltmeter is set on the 2 V range, the current application will indicate the resistance directly in millivolts. B1 is the high current source. B1 is an alkaline battery capable of […]
