Bently Nevada TK15 (80917-01) Dual-Channel Signal Conditioner

Product Description

The TK15 (Part Number: 80917-01) is a specialized, portable dual-channel instrument engineered by Bently Nevada for high-precision machinery diagnostics. This unit functions as both a transducer power supply and a signal conditioner, specifically designed to generate Keyphasor signals. These signals are the industry standard for phase-based vibration analysis, providing the timing reference necessary for tracking rotor dynamics and diagnosing imbalances or misalignments in rotating equipment.

Built for versatility, the TK15 (80917-01) supports two independent channels, allowing engineers to monitor multiple points or redundant signals simultaneously. The hardware is encased in a ruggedized housing designed to withstand the rigors of field troubleshooting, maintaining operational integrity in extreme industrial environments with temperatures ranging from –40°C to +85°C. The TK15 (80917-01) is an essential tool for temporary monitoring during machinery commissioning or when permanent monitoring systems require validation or backup.
