| Model | Description | Typical Application |
|---|---|---|
| 3500/42M-01-00 | Complete monitor kit (includes 176449-02 front card + I/O module) | Standard 4-channel vibration/position monitoring |
| 176449-01 | I/O module (rear card) for 3500/40M/42M series | Field wiring termination and signal conditioning |
| 3500/40M | Dedicated Proximitor Monitor (radial vibration/position) | Where seismic inputs are not required |
| 3500/22M | Transient Data Interface (TDI) | System 1 data collection and diagnostics |
| 3500/15 | Power Supply Module | Required to power the 3500 rack |
| 3300 XL Probes | 8mm proximity probes (e.g., 330101, 330103) | Primary displacement sensors for the 42M |
Q1: What is the primary function of the 176449-02?
It is the front card of the 3500/42M monitor. It processes signals from proximity probes and seismic transducers, continuously comparing input values against user-programmable alarm setpoints to protect rotating machinery.
Q2: How many channels does this module support?
The 3500/42M supports 4 independent channels, each of which can be individually configured for different measurement types (displacement, velocity, or acceleration).
Q3: What is the difference between the 3500/42M and the 3500/40M?
The 42M is the more versatile "Multimode" version, accepting both Proximitor and Seismic inputs. The 40M is typically specialized for Proximitor (displacement) inputs only.
Q4: What does the "M" in 3500/42M signify?
The "M" designation indicates enhanced "Multimode" capability, allowing each channel pair to be independently configured for different measurement types and offering faster data sampling than the standard 3500/42.
Q5: Is the 176449-02 still available?
It is an active/mature product within the 3500 series. Availability depends on stock from authorized distributors and the aftermarket. The 3500 platform remains widely supported, though Bently Nevada continues to develop the next-generation Orbit 60 platform.
The Bently Nevada 330105-02-12-05-02-00 is an 8 mm reverse-mount proximity probe from the 3300 XL series, engineered for non-contact vibration and position monitoring in space-constrained machinery.
The Bently Nevada 330130-085-00-00 is an 8.5-meter standard extension cable for the 3300 XL 8 mm Proximity Transducer System. It connects a 3300 XL proximity probe to its Proximitor® sensor, transmitting eddy-current displacement signals for vibration, axial position, and Keyphasor measurements on critical rotating machinery.
The Bently Nevada 21000-00-00-15-030-04-00 is a Proximity Probe Housing Assembly from the 21000 series, designed to provide a secure, environmentally sealed mounting interface for reverse-mount proximity probes on critical rotating machinery.
The Bently Nevada 330780-50-00 is a 5.0-meter Proximitor® Sensor for the 3300 XL 11 mm Proximity Transducer System. It receives signals from a 3300 XL 11 mm probe and its extension cable, conditioning them into a linear voltage output proportional to shaft displacement for radial vibration, axial thrust position, and Keyphasor measurement.
The Bently Nevada 21747-040-00 is a 4-meter Proximitor probe extension cable designed for the 3300 and 7200 Series Proximity Transducer Systems.
