The world's First 2D Measurement Sensor
is now smarter and better than ever.
Laser Profiling Sensor
Introducing the New ZG2
2
ZG2 Laser Profiling Sensor
Simple "Teach and Go" setup
Three easy steps reduce the setup time for inspections using
color LCD screen and simple menu.
Built-in LCD, No external monitor required.
A profile is displayed
as soon as the power
is turned ON.* Adjust
the Sensor Head
position while
viewing the profile on
the screen.
* In the FUN mode
Select the icon for
the item to be
measured, such as
height, step, or
sectional area.
Simply enclose the
range to be
measured with the
box on the profile.
The ZG2
automatically
optimizes the sensing
conditions.
1st STEP 2nd STEP 3rd STEP
Screen images are simulated.
Display a profile. Select a measurement item. Specify the measurement range.
New Benefits:
»»Faster — up to 10 times faster using the HS
Multi function
»»More»Versatile — Use any of 20 measurement
tools on any of the 8 measurement tasks and 16
available banks for up to 128 tasks
»»Capture»wider»profiles — 2 controllers can
be gang-mounted and measurements taken,
enabling measurement of wide targets from the
2 sensor heads.
»»Improved»Linearity — 5 times better at 0.1% of
Full Scale
»»Data»Storage»Unit — Acquire & collect
measurement values and profile information;
increase available bank data to 4096 banks
»»Measure»nearly»any»target — Profile and
Measure transparent objects including glass
»»Increased»reliability»&»ease — Measure
nearly any target regardless of complexity of color,
shape or material
What is a 2D Profile Measuring Sensor?
The ZG2 Series 2D Profiling Laser Sensor allows entire
shapes, including both height and width, of nearly any
shape, color or material to be profiled and measured
simultaneously via a wide laser beam. It completes the
measurement in parallel.
»»Easy-to-Use — “Teach & Go” setup via intuitive
user interface
»»Fast — 5 mS sampling time
»»Accurate — 0.25 µm resolution in Z direction
»»Live — Built-in LCD monitor for setup and
immediate profile display
»»Optional»Software — Capture, configuration,
data logging, and live monitoring via PC
