Smart Electrostatic Sensor
ZJ-SD
Smart In-line Measurement of Production Site
Static Electricity
The ZJ-SD uses a compact Sensor Head and Amplifier to easily make static electricity visible.
Low repeatability creates the need for a sensor for constant in-line monitoring to properly
capture static electricity. Smart collection of effective data to improve production site
countermeasures is now possible.
Measurements must be made at more than one location and
changes over time need to be monitored for effective discharge.
With the ZJ-SD, multi-point measurements from up to 5 Units can
be made easily if a Calculating Unit is connected between
Amplifiers. And the Smart Electrostatic Sensor measurement data
can be displayed and logged on a personal computer via an
Interface Unit and used for static electricity countermeasures.
Smart Logging of Static Electricity Generation and Discharge
Smart Static Electricity Monitoring
Hand-held devices and large measuring devices are not suitable for
easily measuring static charges of workpieces in-line. The Sensor Head
of the Smart Electrostatic Sensor is small (6 × 6 × 65 mm) and the
bracket has a rotating mechanism, making it possible to mount it even
where space is limited.

The bracket on the Head
enables changing the sensing
direction even after installation.
Smart Amplifier
Static charge is displayed directly.
The best sensing range in the industry at 100 mm/±50 kV.
Sensors that measure static charges are greatly affected by the measurement
distance. The ZJ-SD solves this problem by combining with a ZX-series Displacement
Sensor to enable communicating distance information and thus achieve high-accuracy
measurements.
Note: Ultrasonic Displacement Sensors are also available. Ask your OMRON representative for details.
Long-distance, High-precision Measurements
Workpiece Distance Compensation
Based on the detection principle of electrostatic sensors, the
measurement area is approximately five times the installation
distance. To accurately measure the charge for very small objects,
the size of the workpiece can be input and the current compensated
based on a comparison of the installation distance recorded in the
Preamplifier and the size of the sensing area. Except for the
workpiece, static inside the sensing area, however, must be 0 V.
Accurate Static Charge Measurements
for Minute Workpieces
Workpiece Size Compensation
In addition to distance data compensation performed by the
Displacement Sensor, errors from distance fluctuations can also be
reduced by directly inputting the installation distance into the
Amplifier.
Unaffected by Measurement Distance
A seven-segment, two-row display is provided along with
workpiece charge and threshold value displays.
Settings are easy to make using Up, Down, Left, and Right
Keys.
Effective for measuring static electricity that
occurs when conveying liquid crystal
substrates, static electricity on mounted
PCBs, etc.
Simple Settings Using Key Operations
Our Highest Priority: Easy Onsite Operation
Use the ZX-XC@A (order separately) to extend the cable to
2, 5, or 9 m.
