Product Overview

The 330780-50-00 belongs to the 3300 XL Series. Its product type is an 11 mm Proximitor Sensor. The product classification is Sensor, Transducer & Probe. The current price for this item is ¥4,580 RMB, and the product gross weight is 0.42 kg.

This 330780-50-00 shares the same advanced features as the 3300 XL 8 mm Proximitor Sensor. The total length option is 50, which equals 5.0 meters (16.4 feet) including probe and extension cable. Meanwhile, the mounting option is panel mount, using a traditional configuration. The agency approval option is 00, indicating that no special certifications are required. Thus, this Proximitor Sensor suits standard industrial applications without hazardous area requirements.

Technical Specifications

Physical Dimensions and Mounting

The approximate dimensions are 6.35 cm x 6.12 cm x 8.13 cm (HxWxD). This thin design allows mounting in high-density DIN-rail installations. For traditional setups, you can also use the panel mount configuration. The sensor material is A380 aluminum, providing excellent durability and heat dissipation. Consequently, this compact size saves valuable panel space in control cabinets.

RFI/EMI Immunity

Improved RFI/EMI immunity allows this sensor to achieve European CE mark approvals easily. For example, no special mounting considerations are required for compliance. This RFI immunity also prevents the transducer system from being adversely affected by nearby high frequency radio signals. Unlike older designs, you can install the 330780-50-00 in electrically noisy environments without performance degradation. As a result, nearby walkie-talkies, radios, or variable frequency drives will not disrupt measurements.

Input and Power Requirements

The input accepts one non-contacting 3300 XL 11 mm Proximity Probe. It also accepts the matching extension cable. Regarding power, the sensor requires -17.5 Vdc to -26 Vdc without barriers at 12 mA maximum consumption. With barriers, the range becomes -23 Vdc to -26 Vdc. However, operation at a more positive voltage than -23.5 Vdc may result in reduced linear range. Therefore, always verify your power supply voltage matches these requirements.

Output Specifications

The supply sensitivity is less than 2 mV change in output voltage per volt change in input voltage. This high sensitivity ensures accurate gap voltage readings. The output resistance is 50 Ω, matching standard monitoring system inputs. Thus, the 330780-50-00 provides stable and reliable signal transmission.

System Length

The system length options are 5 or 9 meters including the extension cable. This 5.0 meter configuration suits most standard machinery monitoring applications. For longer distances between probe and Proximitor, consider the 9 meter option instead.

Temperature Range and Humidity

The operating temperature range is -52°C to +100°C (-62°F to +212°F). Meanwhile, the storage temperature range is -52°C to +105°C (-62°F to +221°F). The relative humidity rating is 100% condensing, making the sensor suitable for very wet environments. However, the sensor is non-submersible when connectors are properly protected. It has been tested to IEC 68-2-3 damp heat standards. Consequently, this wide temperature and humidity range suits extreme industrial conditions.

SpringLoc Terminal Strips

The SpringLoc terminal strips require no special installation tools. Unlike screw-type clamps that can loosen over time, these terminals facilitate faster and more robust field wiring connections. Therefore, installation becomes simpler and more reliable.

Factory Calibration

Proximitor Sensors ship from the factory calibrated to AISI 4140 steel by default. For applications with other target materials, calibration is available upon request. Thus, you can order custom calibration for specific rotor materials.

Installation Guide

Follow these steps to install your 330780-50-00 correctly.

1. Power Down Equipment: Disconnect power from the monitoring system. This prevents electrical damage during installation.

2. Choose Mounting Location: Select a panel location with adequate space. Ensure clearance for wiring and future maintenance access.

3. Mount the Sensor: Secure the 330780-50-00 to the panel using appropriate hardware. For DIN rail, snap the sensor onto the rail directly.

4. Connect the Probe Assembly: Attach your 3300 XL 11 mm probe and extension cable to the sensor input. Verify the ClickLoc connectors lock firmly.

5. Wire the Power: Connect -17.5 Vdc to -26 Vdc to the power terminals. Observe correct polarity for reliable operation.

6. Wire the Output: Connect the output signal wires to your monitoring system. The output resistance is 50 Ω.

7. Apply Power: Restore power to the system, and verify the green power LED illuminates.

8. Set Gap Voltage: Adjust the probe gap to the recommended DC voltage. For the 3300 XL system, the typical linear range is -1 to -17 Vdc.

Frequently Asked Questions (FAQ)

1. What is the difference between the 330780-50-00 and the 330780-51-CN?
The 330780-50-00 has a 5.0 meter panel mount configuration with no agency approvals. The 330780-51-CN has the same length but uses DIN mount and includes CN Country Specific approvals.

2. Can I use this sensor with target materials other than AISI 4140 steel?
Yes, factory calibration to other target materials is available upon request. Contact Bently Nevada with your specific material requirements before ordering.

3. What happens if I operate the sensor above -23.5 Vdc with barriers?
Operation at a more positive voltage than -23.5 Vdc may result in reduced linear range. Therefore, always stay within the specified -23 Vdc to -26 Vdc range when using barriers.

4. Is the 330780-50-00 suitable for outdoor installations?
The sensor operates from -52°C to +100°C and handles 100% condensing humidity. However, it is non-submersible. Protect connectors from direct water immersion using connector protectors or silicone tape.

5. Does this sensor require special shielded conduit for CE mark compliance?
No, the improved RFI/EMI immunity satisfies European CE mark approvals without special shielded conduit or metallic housings. Consequently, installation costs and complexity decrease
