Bently Nevada TK3-2E CALIBRATION INSTRUMENT

Product Details

• Manufacturer: Bently Nevada
• Model/Part Number: TK3-2E
• Model Type: Calibration Instrument

General Overview

The TK3-2E and TK3-2G are self-contained calibration instruments, designed for use with proximity transducers (Proximitors). These instruments require proper power connections to function. The TK3-2E operates at 115/230 Vac, and users need to ensure the switch is correctly set to prevent circuit damage. The TK3-2G requires careful handling, as it must be kept upright to prevent oil spillage.
