Bently Nevada TK-3 Proximity System Test Kit

The Bently Nevada TK-3 Proximity System Test Kit is a portable mechanical simulator for checking proximity transducer systems and calibrating position and vibration monitors. It combines a removable spindle micrometer assembly, magnetic base, universal probe holders and a driven wobble plate. The holders accept probe diameters from 5 to 19 mm, while the micrometer provides 0–25.4 mm of travel for static gap checks. The wobble plate produces 50–254 µm (2–10 mils) of peak-to-peak displacement for dynamic verification. Technicians compare the Proximitor sensor output and monitor readings with the applied mechanical displacement. The family includes the electrically driven TK-3e and air-driven TK-3g, with metric or English scale options for checking transducer response and monitor calibration.
