2D Profile Measuring Sensors

ZG - Smart Profile Sensor

The easy way to get your profile

The smart ZG sensor solves ambitious profile mea­surement applications. An easy and intuitive user in­terface enables efficient installation, setup and
operation. The advanced processing technology is
a break-through for the needs of high speed pro­cesses. Precise shape measurement is guaranteed
on challenging materials and surfaces. A built-in
LCD monitor presents the measurement result in
real time.

• Easy to use - intuitive user interface

• Live - built-in LCD monitor for setup and
immediate profile display

• Versatile - 18 measurement tools

• Accurate - 5 µm resolution

• Wide profiles - up to 70 mm

• Fast - 5 ms sampling time

• Smart - powerful PC software for configuration
and post-processing (optional)

Easy to use

Complex operational procedures are time consuming and costly.
The new ZG differentiates from standard products by its usability.
The intuitive icon based menu, enables an easy setup and configu­ration of advanced measurement tasks within 3 steps.

Live - built-in LCD monitor

The built-in LCD monitor of the ZG represents an intuitive user
interface for easy setup and immediate live feedback of measure­ment result. This helps to save time for the initial configuration,
change of measurement task and reduces the training efforts for
personnel. A fine tuning of the settings can be achieved in sec­onds. The LCD monitor enables to check the measurement result
at any time during operation, without the need to connect an exter­nal PC. The reaction time for maintenance activities can be short­ened.

Versatile - diverse measurement functions

The ZG can solve advanced measurement tasks. Up to 18 different
functions are available to meet the requirements of the applications.
They allow to calculate e.g. the width, height, angle or area of the pro­file. The measurement functions can be selected from the easy to
understand icon based user interface on the LCD monitor.

Intelligence inside - automatic adjustment of laser power

In many industrial processes sensors have to deal with difficult or
changing materials. In order to avoid time consuming reconfigura­tions to reliably detect the objects, the sensor by itself has to man­age the constraints of the process. The ZG provides an automatic

adjustment of the laser power, depending on the surface of the
object. The deviation of the reflection, e.g. of different colors can be
compensated by increasing or decreasing the laser power to
achieve the best result.

Further improvements of the measurement result can be achieved
e.g. on shiny surfaces. The reflection level on different parts of the
measurement object can be different, which can result in incomplete
profiles.

Combine!

To complement the profile ZG has the capability to take several
images and to combine them. The "multi-sensitivity function" allows
to adjust the incident light on the different parts of the object and to
retrieve a complete shape.

Flexible - balance between speed and accuracy

The ZG Smart profile sensor offers different modes of operation, which allows adjusting the sensor behavior to the application requirements. The
optimization can be done either towards high speed or high accuracy. For high speed processes the sampling time can be decreased to 5 ms. In
the other direction 5 µm accuracy can be achieved.
