330400-02-CN 加速度计  机器外壳测量

描述

型号：330400-02-CN

这些加速度计用于需要套管加速度测量的关键机械应用，例如齿轮啮合监测。330400是旨在满足美国石油协会加速度计标准670的要求。它

提供50g峰值振幅范围和500mv /g灵敏度。330425是相同的，除了它提供了一个更大的幅度范围(75g峰值)和灵敏度为25mv /g。

大多数常见的机器故障(不平衡，不对中等)发生在转子和源于转子振动的增加(或至少是变化)。对于任何单独的套管测量要有效地对整机进行保护，系统必须不断地将大量的转子振动传递给电机机壳，或传感器的安装位置。

此外，要注意将加速度计传感器安装在轴承座或机器外壳上。安装不当可能会降低换能器的幅度和频率响应和/或产生不代表实际振动的假信号。请参阅相应的使用说明书和使用说明。

根据要求，本特内华达提供工程服务，可以确定适当的机器外壳测量和安装协助(如果需要)。

Description

Model: 330400-02-CN

These accelerometers are used in critical mechanical applications that require casing acceleration measurement, such as gear mesh monitoring. The 330400 is designed to meet the requirements of the American Petroleum Institute's accelerometer Standard 670. it

Provides 50g peak amplitude range and 500mv /g sensitivity. The 330425 is identical except that it offers a much larger amplitude range (75g peak) and a sensitivity of 25mv /g.

Most common machine failures (unbalanced, not moderate) occur in rotors and

An increase (or at least a change) in rotor vibration. For any individual casing

To effectively protect the whole machine, the system must constantly transmit a large amount of rotor vibration to the motor housing, or the mounting position of the sensor.

In addition, care should be taken to mount the accelerometer sensor on the bearing housing or the machine housing. Improper installation may reduce the amplitude and frequency response of the transducer and/or produce false signals that do not represent the actual vibration. Please refer to the corresponding instruction manual and instructions for use.

Upon request, Bente Nevada provides engineering services that can determine appropriate machine housing measurement and installation assistance if required.
