Bently Nevada 1701/15-01 FieldMonitor Proximitor Input Monitor

Product Description

The Bently Nevada 1701/15-01 is a highly advanced and reliable 2 – channel FieldMonitor Proximitor Input Monitor. Engineered to play a pivotal role in machinery health assessment, it specializes in monitoring radial vibration and thrust position in rotating equipment. This device is designed to accept signals from proximity probes either through its associated transducer I/O or internal proximitor module. It then meticulously conditions these incoming signals, converting them into appropriate measurement units. After that, it compares the processed data against user – programmable alarm setpoints. Once the setpoints are breached, it promptly generates appropriate alarm signals for seamless communication to the host control system. Additionally, it can supply current values of its measured parameters to the control system, enabling real – time indication and long – term trending analysis. The embedded self – test features allow the monitor to continuously assess its own integrity, as well as that of its connected transducers. In the event of any problems with the monitor or its associated transducers, a “not ok” condition can be quickly detected and annunciated, ensuring timely intervention.

Features

Dual – Channel Monitoring

The 2 – channel design enables simultaneous monitoring of two different parameters (such as radial vibration and thrust position), providing a more comprehensive view of the machinery’s health.

User – Programmable Alarm Setpoints

Users can customize the alarm thresholds according to the specific requirements of their machinery, ensuring that alarms are triggered at the most appropriate times for preventive maintenance.

Embedded Self – Tests

The built – in self – test capabilities continuously check the monitor’s functionality and the integrity of the connected transducers, enhancing the reliability of the monitoring system.

Robust Connectivity

The M12 connector design and the use of the Modbus RTU protocol ensure stable and efficient communication with other industrial devices, facilitating easy integration into complex automation systems.

Wide Operating Temperature Range

With an operating temperature range of – 40 °C to + 125 °C, it can withstand extreme temperatures, making it suitable for use in a variety of industrial environments, from cold storage facilities to high – temperature processing plants.

Function

The primary function of the 1701/15-01 is to accurately monitor the radial vibration and thrust position of rotating machinery. By capturing signals from proximity probes, conditioning them, and comparing the data against setpoints, it acts as an early warning system. It alerts operators when abnormal vibrations or thrust positions are detected, which could be indicative of issues such as unbalanced rotors, misaligned shafts, or worn bearings. This allows maintenance teams to take proactive measures, such as scheduling maintenance before a major failure occurs, thereby reducing unplanned downtime and extending the lifespan of the machinery.

Use

In industrial applications, technicians first install the proximity probes at strategic locations on the rotating machinery, such as on the bearing housings for vibration monitoring or near the thrust collar for thrust position monitoring. The probes are then connected to the 1701/15-01 monitor either through the transducer I/O or the internal proximitor module. Technicians program the alarm setpoints based on the machinery’s operating specifications. Once the system is set up, the monitor continuously acquires and processes the signals from the probes. Operators can monitor the real – time data on the host control system and receive alarm notifications when necessary. Regular calibration and maintenance of the monitor and probes are carried out to ensure accurate readings.

Application Fields

Power Generation

In power plants, turbines, generators, and pumps are critical components. The 1701/15-01 is used to monitor the radial vibration and thrust position of these machines. By detecting abnormal vibrations, it can prevent issues like blade failures in turbines or bearing damage in generators, ensuring continuous and reliable power generation.

Oil and Gas

In the oil and gas industry, compressors, pumps, and drilling equipment operate in harsh and demanding conditions. The 1701/15-01 helps in monitoring the health of these assets by accurately measuring vibration and thrust position. This data is used to detect early signs of wear and tear, preventing equipment failures that could lead to costly production disruptions.

Manufacturing

In manufacturing plants, a wide range of rotating machinery, such as motors, conveyor belts, and industrial mixers, is used. The 1701/15-01 is employed to monitor the performance of these machines. By ensuring that vibration and thrust levels are within acceptable limits, it helps in maintaining product quality and preventing production line stoppages due to machinery breakdowns.

In conclusion, the Bently Nevada 1701/15-01 FieldMonitor Proximitor Input Monitor is an essential tool for industries that rely on the smooth operation of rotating machinery. Its advanced features, high – quality construction, and wide range of applications make it a valuable asset for any industrial facility looking to enhance its machinery monitoring capabilities and improve overall operational efficiency.
