Bently Nevada TK81 Tunable Filter/Vibration Meter

Product Description
The Bently Nevada TK81 is a Tunable Filter/Vibration Meter designed for basic vibration measurements. This portable, handheld instrument displays vibration in both unfiltered and filtered modes and accepts inputs from displacement, velocity, and acceleration transducers, making it useful for diagnosing vibration problems at specific frequencies.

Key Features

• Portability: Handheld and easy to use in the field.
• Display: 4-line by 16-character LCD.
• Input Impedance: 95 kΩ.
• Filtering Capability: Useful for diagnosing specific vibration issues.
