Chapter 1 Installation
• When placing other sensors next to each other, separate the sensor tops by
not less than 10 times the sensor tip diameter to prevent interference.
• The sensor must be installed on a surface with adequate rigidity that is not
affected by an outside vibration. If the sensor vibrates, an accurate
measurement cannot be taken.
• For shapes and dimensions around the sensor, refer to the installation
examples (1…3) below. If a piece of metal other than the target is near the
sensor, an accurate reading cannot be taken.
If it is unavoidable to install the sensor as illustrated in examples 4…7,
check the characteristics at the attachment completed conditions.
Table 1 - Installation Examples
Example Description
Example 1 (most recommended) Dimension X is to be not less than 1.2 times the tip
diameter.
Example 2 (recommended) Dimension X is to be not less than 1.2 times the tip
diameter
Dimension Y is to be not less than 3 times the tip
diameter.
Example 3 (recommended) After constructing as shown in example 2, the area shown
by the shaded line in the illustration is filled with resin or
other insulating material.
