Compact Head and Digital Display
Amplifier with Minimum Mounting Space
Compact Sensor Head and Smart
Amplifier
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.
Smart Logging of Static Electricity
Generation and Discharge
Smart Static Electricity
Monitoring
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.
Our Highest Priority: Easy Onsite Operation
Simple Settings Using Key Operations
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.
Remote Detection
Use the ZX-XC[]A (order separately) to
extend the cable to 2, 5, or 9 m.
Workpiece Distance Compensation
Long-distance, High-precision Measurements
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.
Unaffected by Measurement
Distance
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.
Workpiece Size Compensation
Accurate Static Charge Measurements for Minute Workpieces
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.
