FAQ
Frequently Asked Questions (FAQs)
Q1: What is the primary function of the Bently Nevada 3500/25 Enhanced Keyphasor Module?
A1: The module generates digital Keyphasor signals from rotating machinery to provide timing information for monitoring shaft speed and vibration phase measurements.
Q2: What types of sensors are compatible with the module?
A2: The module supports both proximity probes and magnetic pickups for signal input.
Q3: What is the maximum speed range the module can measure?
A3: It supports input frequencies up to 1,200,000 cpm (20 kHz) and outputs up to 99,999 cpm (1,667 Hz).
Q4: How many channels are available on a single 3500/25 module?
A4: Each module provides two channels for Keyphasor signal input and output.
Q5: Is the module suitable for use in hazardous environments?
A5: Yes, when ordered with appropriate options, the module carries approvals for Class I, Div 2, and ATEX/IECEx Zone 2 environments.
Q6: What are the installation slot requirements in a 3500 rack?
A6: The main module requires one half-height front slot, and the I/O module occupies one full-height rear slot.
Q7: What is the minimum speed required for magnetic pickups to operate properly?
A7: Magnetic pickups require a shaft speed greater than 200 rpm (3.3 Hz).
