The Bently Nevada TK3-2E (Order Number 14700-01) is a high-precision calibration instrument designed to verify the performance of proximity transducer systems. As a critical tool for machinery protection, it allows technicians to simulate both static shaft position and dynamic vibration. By moving a calibrated target toward or away from a proximity probe tip, the TK3-2E confirms that the Proximitor® sensor output and the associated monitor readouts are perfectly aligned, ensuring the integrity of SIL-rated machinery protection loops.
This electric-driven unit features a dual-purpose design: a precision spindle micrometer for DC (position) calibration and a motorized wobulator for AC (vibration) simulation. The TK3-2E is engineered to withstand industrial rigors while maintaining laboratory-level accuracy, featuring a rugged housing that meets IP54 standards when closed. Whether used for pre-installation checks or routine preventive maintenance, the TK3-2E 14700-01 provides the mechanical displacement necessary to confirm that sensors are functioning within their linear range and that alarm setpoints are accurately triggered.
