The TK-3E is a compact eddy-current probe designed for case vibration monitoring on rotating equipment where the standard 8mm proximity probe is too large. The TK-3E is often used for monitoring bearing housing vibration on small-to-medium motors and pumps.
TK-3E probes connect to a proximitor (separate signal conditioner) and provide 4-20 mA or voltage output proportional to vibration amplitude.
