Magnetic Sensor Amplifiers

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.

The DMC comes in 4 versions, each having different trigger levels according to the requirements of the intended application.

DMC A

This version is intended for fuel flow sensors which have a very low trigger level.

Heavy filtering minimises the possibility of interference, resulting in significant variation of the trigger level with frequency.

DMC B

This version is intended for engine trigger sensors that have insufficient amplitude to trigger a logic level input.

Minimal filtering avoids delays in the signal. The trigger level does not vary significantly at normal operating frequencies.

DMC C

This version is intended for ignition system input conditioners, typically used in drag racing, for measuring ignition timing.

DMC D

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.
