Part No: #53111

OVERVIEW

Three versions of Dual Magnetic Converters (DMCs) are available (A, C and D). DMCs convert magnetic style signals to an open collector output signal (square wave). This makes a typical magnetic sensor behave as a switched or hall effect sensor, thus making the signals suitable for use with ECUs and loggers. A single DMC can convert two independent magnetic sensor signals.

INTENDED USE

This DMCA, is intended for use with fuel flow sensors that have a very low trigger level.

All DMC versions contain trim pots. At manufacture, these are pre-set to specification for the relevant DMC version, they should not be adjusted after purchase.

OPERATION

For fuel flow application, the polarity of the sensor connection is generally not important since the signal is generally a sine wave. The measuring equipment should be configured to use the negative going edge if possible; however, positive going edge will also generally work satisfactorily. To minimise the possibility of interference at very low trigger levels, this model includes heavy filtering that results in significant variation of the trigger level with frequency. The variation is tailored to match a typical flow sensor, where the output signal increases as the frequency increases.

AVAILABLE DMC VERSIONS

Two other versions are available to cater for different purposes and different trigger levels:

DMCC — used as a conditioner for ignition system inputs.

53117 – DMCC - DUAL MAGNETIC CONVERTER - GENERAL PURPOSE

DMCD — used on magnetic wheel speed sensors.

53118 – DMCD - DUAL MAGNETIC CONVERTER FOR WHEEL SPEED SENSORS
