Bently Nevada 330780-90-00

1. Specification

Operating temperature range: -35° to +65°C; storage temperature range: sustained use column 3, +35 (3), (a) test -52° to + 105°C loop.

Linear range: about 2mm.

Sensitivity: 3.94v/mm typical (100mv/mil), sensitive to small displacement changes.

Frequency response: 0-10kHz, which is operatively due to the stillness of the mechanism and speed accuracy.

Amplitude-frequency response: attenuations at less than 1% at 0 to 1kHz and at less than 5% at 10kHz.

Phase-frequency response: phase differences at less than -10° at 0 to 1kHz and at less than -100° at 10kHz.

Output impedance: 50Ω.

Supply voltage: -17.5 to -26Vdc (no safety barrier processed) 12mA maximum; -24 to -26Vdc (with safety barrier processed), when it works under voltage more than -23.5Vdc, the range linearity would diminish.

Power supply voltage sensitivity: a change in supply voltage by 1 volt produces an output voltage change of less than 2mV.

2. Feature

High-precision measurement and monitoring:  As an XL 11 mm proximity sensor, it allows accurate measurement of vibration, displacement, and other axis motion parameters of rotating machinery. The measuring target range is from 1.02 to 20.0 mm (0.040 to 0.787 inches), with the resolution into the micrometer range of 0.0025mm (also see less). It can very efficiently capture minute changes and present precise data support for the monitoring of equipment status.

High reliability: Due to the stability of performance and high-precision measurement, the Bently Nevada 330780-90-00 has shown extreme reliability during long-term operation in industrial environments. It can reliably and continuously provide prompt and accurate monitoring data to the user and reduce the downtime occurrence and possibilities of equipment in respects to failures associated with sensors which will automatically cut maintenance and the associated costs and also production losses considerations.

3. Application

Machinery manufacturing industry

Machine tool spindle monitoring: Bently Nevada 330780-90-00 can monitor the vibration and displacement of machine tool spindles, enhances the processing accuracy, tool life, and the quality and reliability of machined products, thereby increasing the production capabilities of the firms.

Performance test of rotating mechanical parts: While developing and producing the mechanical part, different kinds of vibration and displacement tests are executed on the rotating parts to assess their performance and reliability, giving justification for the optimization and improvement of the product.

Papermaking industry

Monitoring of papermaking machine cylinder: Bently Nevada 330780-90-00 can monitor the vibration and displacement of the papermaking machine cylinder to eliminate the cylinder from affecting the quality of paper through too much vibration, and it can be timely discovered also for cylinder failure, to reduce the duration of maintenance and cost to the equipment.

Monitoring of pulp agitator: Bently 330780-90-00 can be installed at the tip of the pulp agitator shaft for vibration and displacement measuring; this guarantees even mixing of the pulps and higher quality of the paper and efficiency of production.

Iron and steel industry

Monitoring of rolling mill: Bently 330780-90-00 can be used for monitoring vibration and displacement of rolling mill rollers, to timely adjust position and status of rollers to improve rolling accuracy, ensure steel quality and quantity, and prolong the life of rolling mill rollers.

Monitoring of blast furnace blower: Bently Nevada 330780-90-00 can monitor and communicate in real time, vibration and displacement of the shaft of the blast furnace blower so that the blower runs stably and provides sufficient oxygen to keep the iron making process flowing smoothly.
