这些加速度计用于关键机械套管加速度测量的应用必需的，如齿轮啮合监测。330400是旨在满足美国石油的需求加速计协会标准670。它提供了振幅范围为50 g峰值，灵敏度为100 mV/g。330425是相同的，除了它提供了更大的振幅量程(75 g峰值)和25 mV/g的灵敏度。如果正在进行总体的住房测量机器的保护，应该考虑到测量对每个应用的有用性。最常见的机器故障(不平衡、错位、等等。)起源于转子并导致增加(或至少一个变化)。为了任何住房仅测量对整个机器有效保护，必须将大量的转子振动忠实地传递到轴承箱或机器外壳，或者更具体地说，安装到传感器。此外，应该注意锻炼身体传感器的安装。可能会导致安装不当传感器性能下降，和/或产生不代表实际机器的信号振动。输出对速度的积分会恶化这个。如果集成到，应特别小心速度。对于高质量的速度测量，330500应使用Velomitor传感器。根据要求，我们可以提供工程服务确定住房测量的适当性有问题的机器和/或提供安装援助。

These accelerometers are necessary for the application of key mechanical casing acceleration measurement, such as gear meshing monitoring. 330400 is an accelerometer association standard 670 designed to meet the demand for oil in the United States. It provides an amplitude range of 50 g peak and a sensitivity of 100 mV/g. 330425 is the same, except that it provides a larger amplitude range (75 g peak) and a sensitivity of 25 mV/g. If the overall protection of the housing measurement machine is being carried out, the usefulness of the measurement for each application should be considered. The most common machine malfunctions (imbalance, misalignment, etc.) originate from the rotor and cause an increase (or at least one change). In order for any housing to only measure effective protection for the entire machine, a large amount of rotor vibration must be faithfully transmitted to the bearing box or machine casing, or more specifically, installed in sensors. In addition, attention should be paid to the installation of exercise body sensors. Improper installation may result in decreased sensor performance and/or signal vibrations that do not represent the actual machine. The integration of output with speed will worsen this. If integrated, special attention should be paid to speed. For high-quality speed measurements, a Velomitor sensor should be used for 330500. According to the requirements, we can provide engineering services to determine the appropriateness of housing measurements and/or provide installation assistance.
