DMC-D Converter: Wheel Speed

Details

This version is intended for magnetic wheel speed sensors. The signal should be symmetrical around zero volts. Heavy filtering minimises the possibility of interference, resulting in significant variation of the trigger level with frequency.

The Dual Magnetic Converter (DMC) converts magnetic style signals to open collector output signals – a square wave. This makes a typical magnetic sensor behave as a switched or Hall Effect sensor, to make the signals suitable for use with MoTeC ECUs and loggers. This allows magnetic sensors to be used in applications where previously a Hall sensor was required, for example when using the digital inputs on an ECU to measure wheel speed. A single DMC can convert two independent magnetic sensor signals.

Frequently Asked Questions About DMC-D Converter: Wheel Speed

What is the specific application for the DMC-D version?

The DMC-D is specifically designed for converting signals from magnetic (VR) wheel speed sensors. It requires the input signal to be symmetrical around zero volts.

Why does the DMC-D use heavy filtering?

Wheel speed data can be susceptible to electrical noise. The heavy filtering minimizes interference, ensuring that the ECU receives clean data for critical functions like Traction Control and Launch Control.

What is the output signal format?

The converter takes the analog magnetic signal and outputs an open collector square wave. This allows the magnetic sensor to mimic a Hall Effect sensor, which is required for most MoTeC digital inputs.

How does the filtering affect the trigger level?

Due to the heavy filtering required to reject noise, the trigger level on the DMC-D varies significantly with frequency, but this is an acceptable trade-off for reliable wheel speed monitoring.

How many wheel speed sensors can connects to one DMC-D?

A single DMC unit allows you to convert two independent magnetic sensor signals. You would typically need two DMC units to monitor all four wheels on a vehicle.
