With thousands of installed units in the field it has proven to be the world’s most reliable, virtually indestructible ESP sensor available. ACE is the only ESP sensor in the world with a 2-year warranty. The instrument uses a patented method to electrically protect the device during damaging motor overloads or phase to ground shorts, which typically prove fatal to other instruments. As a result, the instrument is less than half the size (it can run on 375 systems), half the weight of competing units.
