Installation Notes

1. Mounting method

When selecting a transducer for mounting, careful consideration should be given to the effect that different mounting methods may have on the amplitude and frequency of the transducer. Sensors can be mounted in a variety of ways: hand-held probes, glued, magnetic mounts, threaded mounts, etc. Different mounting methods produce different mounting stiffnesses, resulting in changes in the measurement frequency of the sensor. Different mounting methods produce different mounting stiffness, resulting in changes in the sensor's measurement frequency, the higher the stiffness, the wider the measurement frequency. Therefore, when installing the sensor, it is best to bolt the sensor directly to the object to be measured.

2. Installation surface

The bottom surface of the sensor finish to <10μm, but also hope that the user of the object to be measured on the surface grinding, improve the finish and smoothness, so that the object to be measured to install the surface roughness of less than 10μm. Clean the bottom surface of the sensor and the mounting surface to ensure that the surface is free of foreign matter.

3. Bolt connection method

Bolt connection is the most reliable installation method, first of all, in the clean and flat mounting surface drilling a mounting threaded hole (hole depth should be longer than the bolt). Secondly, in order to ensure effective contact between the upper and lower end surfaces, it is best to apply a layer of grease on the bonding surface to increase the contact stiffness, which ensures that the entire bottom surface of the sensor can be very good rigid contact with the measured object. Finally, use a torque wrench to install the sensor to the mounting surface, the installation of the screw holes must be perpendicular to the surface, the installation torque of 2.5 ~ 5NM.

4. Mounting method of magnetic base

When mounting the magnetic base, due to the strong suction force of the magnetic base, so special attention should be paid during installation. Avoid direct vertical adsorption on the mounting surface during installation, as vertical adsorption will produce large transient impacts that may affect the testing accuracy of the sensor. The correct method is to install it at an inclined angle.
