ZJ-SD Features
The ZJ-SD is a series of static electricity sensors. The purpose of these sensors is to measure
the electric potential of the surface of a workpiece charged with static electricity.
Example: Measurement of the potential of a PCB
■ High-precision Detection by Distance Correction
The sensor that measures the charged amount of the workpiece is greatly dependent
on the distance up to the workpiece.
The ZJ-SD series can be connected to a ZX displacement sensor so that distance
correction can be performed on the charged amount using that measurement data and
non-uniform workpieces can be measured to high precision.
Also, if the installation distance up to the workpiece is fixed beforehand, distance
correction can be performed and highly accurate measurement ensured by directly
inputting the distance to the ZJ-SD.
