Overview
The Bently Nevada TK15 is a Keyphasor Conditioner and Power Supply module designed for use with Bently Nevada permanent monitoring systems, particularly the 3300/7200 series proximity probes. Its main function is to process the raw signal from a Keyphasor probe, producing a clean, digital pulse for use by machinery monitoring instruments (such as the 3500 series).
The TK15 also provides the regulated DC bias voltage needed to operate the proximity probe and extension cable. By delivering a reliable Keyphasor signal, the TK15 establishes the timing reference for vibration analysis, enabling accurate measurement of rotational speed (RPM), phase angle, and vibration vectors.
This makes the TK15 critical for machinery protection and predictive maintenance, ensuring that large rotating equipment is monitored accurately and safely.

FAQ: Bently Nevada TK15
Q1: What is the primary function of the Keyphasor signal?
A1: It provides a precise zero-degree timing reference, allowing the system to measure vibration phase angles, which is essential for detecting imbalance, misalignment, and other mechanical faults.
Q2: Why does the TK15 provide a negative DC voltage output?
A2: Bently Nevada proximity probes require a negative DC bias (typically 6–24 VDC) to generate the electromagnetic field used for gap measurement. The TK15 supplies this regulated power.
Q3: Is the TK15 compatible with accelerometers?
A3: No. The TK15 is designed specifically for Keyphasor proximity probes. Accelerometers and velocity sensors require separate signal conditioning and power (e.g., 24 VDC two-wire or 4–20 mA current loop).
