It is compact, durable, and ideal for applications that require high-performance proximity sensing in demanding industrial environments.

Technical Specifications

Function and Working Principle

The 132306-02 Backup Proximity Sensor functions by detecting the proximity of metallic objects without physical contact. Here’s how it operates:

• Proximity Detection: This sensor uses electromagnetic fields to detect the presence or absence of metal objects within its specified range (typically up to 10 mm). When an object enters or exits the sensing range, the sensor outputs a digital signal (on or off), indicating the presence of the object.
• Backup Role: As a backup sensor, it ensures that if the primary proximity sensor fails, the system still has a reliable means of monitoring critical machine parts.
• Output Signal: The on/off output signal from the proximity sensor can be used to trigger alarms or send data to a condition monitoring system, providing real-time insights into the machine’s status.
• Shielded Design: The sensor is shielded to reduce interference, ensuring reliable operation in industrial environments with high electrical noise.

Role in Industrial Monitoring Systems

The Bently Nevada 132306-02 Backup Proximity Sensor plays an important role in machine condition monitoring systems by providing redundant sensing capability to enhance system reliability:

• Backup Redundancy: This sensor is designed to act as a backup solution to the primary proximity sensors in industrial systems, ensuring that if one sensor fails, the monitoring system still receives data.
• Real-Time Monitoring: It provides real-time monitoring of the relative position of machine components, contributing to predictive maintenance systems that detect early signs of equipment failure.
• Prevention of Downtime: By offering a fail-safe backup option, this sensor helps to prevent unplanned downtime caused by sensor malfunction, ensuring continuous monitoring and data collection.
• Remote Diagnostics: The sensor can be connected to remote diagnostics systems, allowing operators to monitor equipment performance from a distance and make timely decisions.

Industrial Applications

The 132306-02 Backup Proximity Sensor is widely used in industries where continuous condition monitoring and the reliability of machinery are critical:

• Power Generation: Installed in power plants to monitor the position of rotating machinery components such as turbines, generators, and pumps. It ensures that critical sensors are always operational, even if the primary sensors fail.
• Oil and Gas: Used in offshore and onshore oil rigs to monitor rotating equipment like compressors, motors, and valves. The backup sensor ensures there is no loss of data in case of primary sensor failure.
• Automotive and Aerospace: In the aerospace and automotive industries, backup proximity sensors are used to monitor key components in engines, gearboxes, and other critical machinery, ensuring that health data is always available for analysis.
• Manufacturing and Industrial Automation: The sensor is used on robotic arms, automated conveyors, and other automated systems where precision is key. It helps maintain continuous monitoring even when other sensors face issues.
• Mining and Heavy Industry: Used in heavy machinery such as crushers, excavators, and conveyors to ensure that backup monitoring data is always available, helping prevent unexpected machinery failures.

Installation and System Integration

The 132306-02 Backup Proximity Sensor can be easily installed in a variety of industrial setups to monitor critical machinery. Here’s a step-by-step guide to ensure correct installation:

1. Determine Mounting Location: Choose an appropriate location for the sensor, ensuring it has the correct alignment with the machinery or moving parts. The sensor should be installed in a way that it can detect proximity to key components.
2. Mounting the Sensor: Secure the sensor using standard mounting hardware (brackets or screws) designed for industrial sensors. Ensure it is stable and will not be affected by vibrations or external factors.
3. Wiring: Connect the sensor to the monitoring system using the appropriate wiring. The digital signal output can be integrated into a larger condition monitoring system, which will analyze the sensor data and generate alerts.
4. Testing the System: Once installed, perform a functional test by bringing a metallic object into the sensor’s detection range. Verify that the sensor output switches from off to on (or vice versa) as expected.
5. Sensor Calibration: If necessary, calibrate the sensor to ensure optimal range and accuracy.
