Component Description
The part number 1900/65A-00-00-01-00-00 refers to a specific configuration from the Bently Nevada 1900/65A Proximity Transducer System.
1900/65A: This designates a General-Purpose Proximity Transducer System (Radial Vibration). This is not a single module but a pre-packaged kit designed for measuring shaft relative vibration using eddy current technology. A typical kit includes a proximity probe, an extension cable, and a proximitor (the signal conditioner/demodulator).
-00-00-01-00-00: This extended suffix defines the exact factory configuration of the entire transducer system. It specifies a combination of the following:
Probe Type and Length: The specific model and threaded length of the proximity probe.
Cable Type and Length: The type (e.g., integral, armored) and length of the extension cable.
Proximitor Model: The specific model of the proximitor, which may be a rack-mounted card or a standalone device.
Connectors and Accessories: The types of connectors and any included mounting hardware.
In essence, this part number represents a complete, ready-to-install vibration measurement system for a single point. It provides all the necessary components to measure the dynamic motion (vibration) of a shaft relative to its bearing.
Key Parameters
The following table outlines the key parameters for a standard 1900/65A transducer system. Note: Exact values depend on the specific configuration defined by the suffix.
| Parameter | Specification |
|---|---|
| System / Product Line | Bently Nevada 1900/65A |
| Primary Function | Shaft Relative Vibration Measurement |
| Measurement | Vibration (displacement, mils or µm peak-to-peak) and DC Gap (position, mils or µm DC). |
| Components | 1 Proximity Probe, 1 Extension Cable, 1 Proximitor |
| Probe Diameter | Typically 8 mm (standard for general-purpose vibration). |
| Linear Range | Typically 0 to 80 mils (0 to 2 mm) peak-to-peak. |
| Frequency Response | 0 to 10,000 Hz (0 to 600,000 CPM). |
| Gap Range | Typically 10 to 90 mils (0.25 to 2.3 mm) for setup. |
| System Output | -1 to -11 VDC to a monitoring system (scaled for vibration and gap). |
| Power Supply | Typically -18 to -26 VDC to the proximitor. |
| Operating Temperature | Probe: Up to 150°C (302°F) with standard cable; higher with high-temp cable. |
| Probe Dimensions | Body: Typically 15 mm diameter. Length: Configuration-specific (e.g., 25 mm, 40 mm). |
| Proximitor Dimensions | Rack-Mount Card: Approx. 193mm x 55mm x 200mm (HxWxD) / Standalone: Varies. |
| Weight (Total Kit) | Approx. 1.0 - 1.5 kg (2.2 - 3.3 lbs), highly dependent on cable length. |
Application Scenarios
The 1900/65A transducer system is a fundamental building block for machinery condition monitoring and is applied across a vast range of industrial equipment.
General-Purpose Machinery Vibration Monitoring:
Application: Pumps, Motors, Fans, Gearboxes, and Compressors.
Function: Installed at bearing housings to measure shaft vibration. It provides early detection of common faults like unbalance, misalignment, and rolling element bearing defects, enabling predictive maintenance.
Integration with Monitoring Systems:
Application: As an input to Bently Nevada 3500, 3300, or other PLC/DCS/SCADA systems.
Function: The proximitor conditions the raw signal from the probe and provides a standardized analog voltage output (-1 to -11 VDC) that is easily connected to the input of a larger monitoring system for display, alarming, and data recording.
Machine Protection on Non-Critical Assets:
Application: Standalone protection for less critical equipment.
Function: The output from the proximitor can be wired directly to a simple relay module or PLC to provide basic vibration-based alarm and shutdown functions, protecting the machine from severe damage.
Portable Data Collection Routes:
Application: Plant-wide predictive maintenance programs.
Function: The buffered output from the proximitor provides a clean, scaled signal that can be safely connected to a portable data collector for routine vibration route measurements and trend analysis.
