2. Product introduction

The BENTLY NEVADA 18745 – 03 is a high – performance proximitor sensor, an integral part of the well – known 7200 series. This sensor is engineered to provide precise and reliable non – contact displacement measurements, making it a crucial component in the monitoring and maintenance of rotating machinery. By leveraging advanced eddy current technology, the 18745 – 03 can accurately detect changes in the distance between the sensor and the target, translating these into valuable data for assessing the condition of industrial equipment.

3. Core advantages and technical highlights

Non – contact eddy current measurement: The 18745 – 03 employs non – contact eddy current technology, which is a key advantage in industrial applications. Since there is no physical contact between the sensor and the target surface, there is no wear and tear on either the sensor or the equipment being monitored. This not only extends the service life of the sensor but also ensures the integrity of the machinery, reducing the risk of damage caused by mechanical contact. For example, in high – speed rotating shafts, traditional contact – based sensors could cause friction and eventually lead to premature wear of the shaft. The non – contact nature of the 18745 – 03 eliminates this concern, allowing for continuous and reliable monitoring over long periods.

High accuracy and resolution: With an accuracy of ±0.5% full scale and a resolution of 0.1 µm, the 18745 – 03 is capable of providing highly precise displacement measurements. This level of accuracy is essential for detecting even the slightest changes in the position or vibration of machinery components. In applications where tight tolerances are critical, such as in precision – engineered turbines or high – speed motors, the 18745 – 03 can accurately measure parameters like shaft eccentricity, axial position, and radial vibration. By providing such detailed and accurate data, it enables operators to identify potential issues at an early stage, preventing costly breakdowns and ensuring smooth operation of the equipment.

Wide temperature operating range: Operating within a temperature range of – 40 °C to + 200 °C, the 18745 – 03 is designed to withstand extreme environmental conditions. This makes it suitable for use in a variety of industries, including those with harsh operating environments. For instance, in oil and gas refineries, where equipment may be exposed to both extremely cold temperatures during winter months and high – temperature process streams, the 18745 – 03 can maintain its performance. Similarly, in industrial furnaces or high – temperature manufacturing processes, the sensor can continue to function accurately, providing reliable data for machinery health monitoring.

High signal – to – noise ratio and reverse polarity protection: The 18745 – 03 offers a high signal – to – noise ratio, ensuring that the measured data remains reliable even in noisy industrial environments. This is crucial as industrial settings are often filled with electromagnetic interference and mechanical vibrations that could potentially distort sensor readings. Additionally, the sensor is equipped with reverse polarity protection. In the event of an accidental reversal of the power supply, this protection feature safeguards the sensor from damage, reducing the risk of unplanned downtime due to sensor failure.

4. Typical application scenarios

Rotating machinery vibration and position monitoring: In power generation plants, the 18745 – 03 is commonly used to monitor the vibration and position of steam turbines and generators. By continuously measuring the shaft vibration and axial position, it can detect signs of misalignment, unbalanced forces, or bearing wear. For example, if a turbine shaft starts to vibrate abnormally due to a damaged bearing, the 18745 – 03 will accurately measure these changes and send signals that can be used to trigger maintenance procedures. In manufacturing plants, it can be used to monitor the operation of high – speed motors and spindles, ensuring that they are running within the optimal range and preventing any potential damage to the production equipment.

Condition monitoring in reciprocating machinery: Reciprocating compressors and pumps are widely used in industries such as oil and gas, petrochemical, and manufacturing. The 18745 – 03 can be installed to monitor the position and vibration of pistons, rods, and other reciprocating parts. By measuring the displacement of these components, it can detect issues like piston wear, misalignment, or valve problems. In a reciprocating compressor, if the piston starts to move off – center, the 18745 – 03 will detect the change in displacement, allowing operators to take corrective actions before it leads to a major failure.

Precision manufacturing and quality control: In precision manufacturing processes, such as the production of high – end electronics or aerospace components, the 18745 – 03 can be used for quality control purposes. It can measure the displacement and vibration of machine tools, ensuring that they are operating with the required precision. For example, in a CNC machining center, the sensor can monitor the position of the cutting tool and the workpiece, detecting any deviations from the programmed path. This helps to ensure that the manufactured parts meet the strict quality standards of the industry.

5. Related model recommendations

BENTLY 3300 series proximity sensors: The 3300 series sensors are also widely used in industrial machinery monitoring. While the 18745 – 03 is part of the 7200 series, the 3300 series offers similar non – contact displacement measurement capabilities. In some industrial setups where a combination of different sensor models may be required for comprehensive monitoring, the 3300 series can be used in tandem with the 18745 – 03. They may have different features such as slightly different measurement ranges or signal processing capabilities, which can be selected based on the specific requirements of the machinery being monitored. For example, in a large – scale industrial complex with a variety of equipment, some areas may benefit from the 18745 – 03’s higher temperature tolerance, while others may require the different measurement range offered by a 3300 series sensor.

BENTLY 9000 monitoring systems: When used in conjunction with the 18745 – 03, the BENTLY 9000 monitoring systems can provide a comprehensive solution for machinery health monitoring. These systems can collect, analyze, and display the data from the 18745 – 03 sensor, along with data from other sensors in the system. They often come with advanced software features for trend analysis, alarm management, and reporting. In a power plant, the 9000 monitoring system can integrate the data from multiple 18745 – 03 sensors installed on different turbines and generators, providing operators with a unified view of the equipment’s condition and enabling more informed decision – making regarding maintenance and operation.

Compatible extension cables and mounting accessories: To ensure proper installation and optimal performance of the 18745 – 03, it is important to use compatible extension cables and mounting accessories. BENTLY NEVADA offers a range of these accessories that are designed to work specifically with the 7200 series sensors. The extension cables are engineered to maintain the integrity of the sensor signal over long distances, while the mounting accessories are designed to ensure secure and accurate installation of the sensor on the machinery.
