330180-50-00 Proximitor Power Supply
Description:
The part number 330180-50-00 refers to a DIN Rail Mount Power Supply for Bently Nevada Proximitor Transducer Systems. This device is a dedicated power module designed to convert standard AC or DC plant power into the precise, regulated negative DC voltage required to operate one or more proximitors (oscillator/demodulators).
It is a key component in systems where proximitors are not mounted in a centralized rack (like a 3500 system) but are instead distributed locally near the machinery. This power supply ensures the proximitors receive clean, stable power, which is critical for obtaining accurate and reliable vibration and position measurements.
Parameters & Specifications
The following table details the key parameters for this specific power supply.
| Parameter | Specification / Interpretation |
|---|---|
| Part Number | 330180-50-00 |
| Device Type | DIN Rail Mount Proximitor Power Supply |
| Input Power | -50- = Typically specifies the input voltage. "50" often indicates a 120 VAC input. Other common inputs are 240 VAC or 24 VDC. |
| Output Voltage | -18 VDC to -24 VDC (regulated, filtered). The standard voltage for powering 8mm and 5mm proximity probe systems. |
| Output Current | Typically 150 mA to 200 mA (sufficient to power multiple proximitors). |
| Mounting | Standard DIN rail (35 mm TS-35/7.5 or 15) |
| Electrical Connection | -00 = Typically screw terminal blocks. |
| Operating Temperature | -20°C to +70°C (-4°F to +158°F) - typical for industrial power supplies. |
| Housing Material | Plastic or metal enclosure. |
| Typical Dimensions | Approx. 100 mm (H) x 50 mm (W) x 80 mm (D) (3.94 in x 1.97 in x 3.15 in) |
| Typical Weight | Approx. 0.3 kg (0.66 lbs) |
| Safety Standards | Typically conforms to industrial safety standards (e.g., UL, CE). |
Important Note: *The interpretation of the "-50-" suffix as 120 VAC is common but not universal. For the exact input voltage range, output current rating, and wiring diagrams, consulting the official Baker Hughes Bently Nevada 330180 Series Power Supply Datasheet for this exact part number is essential.*
Application Scenarios
This power supply is a foundational component for installing proximity transducer systems in distributed or standalone configurations. Its primary role is to provide reliable power.
Distributed Proximitor Cabinets: Used in local junction boxes or small control panels mounted near machinery (e.g., on a skid) to power one or more proximitors that are located away from the main control room rack.
System Retrofits and Upgrades: When adding new vibration monitoring points to an older system that does not have a centralized monitoring rack, this power supply provides the necessary power for the new proximitors.
Standalone Machinery Monitoring: Used in applications where a single machine is monitored by a dedicated system, and a full 3500 rack is not justified. The power supply is mounted on a DIN rail inside a local enclosure along with the proximitors.
Redundant Power Configurations: In critical applications, two or more of these power supplies can be configured in a redundant (parallel) setup to ensure continuous operation even if one power supply fails.
Replacement for Obsolete Power Supplies: Used as a direct replacement for failed or aging power supplies in existing field-mounted panels.
Typical Use Case:
This power supply would be installed on a DIN rail inside a NEMA 4X junction box on the deck of a compressor. It would take 120 VAC plant power and convert it to -24 VDC to power four proximitors monitoring radial vibration and axial position on the compressor, ensuring they receive clean, stable power for accurate measurements.
