2.3.2 Sensor Types
The iVu TG sensor includes three Sensor Types:
Area Sensor
An Area type sensor is used to ensure that a feature, or some features, are present on a part. When setting up the sensor for an Area
inspection, a feature, such as a drilled hole, is identified as well as the size (area) expected. If there is more than one of the identified
features on a part, the number expected can be set as well. During the inspection, the sensor will verify that each part or package in-
cludes the specified number of features. Some example applications include:
• Inspections that check for drilled holes on a part
• Inspections that check for correctly stamped parts
• Inspections that ensure proper packaging (for example, check that a packing slip exists in or on a box; test whether a vial is properly
capped)
• Inspections of blister packs
Blemish Sensor
A Blemish type sensor can be used to find flaws on a part (for example, scratches on a disc), or it can be used to make sure a feature
exists on a part. Although verifying a feature is present on a part is more commonly an application for an Area sensor, a Blemish sensor
may be a better option when dealing with variable materials or uneven lighting. Some example applications include:
• Inspections that check for scratches on a part, and reject parts where the scratches are too numerous or larger than acceptable
• Inspections that check for the presence of some label or marking on a part that may vary in color
Match Sensor
A Match type sensor is used to verify that a pattern, shape, or part in any orientation matches a reference pattern. The reference pattern
is taught during setup. A reference pattern might include alphanumeric characters, logos, or any other shapes. During an inspection, the
sensor checks that each part or package being inspected matches the reference pattern. Additionally, if there is more than one of the
identified pattern, the number expected can be set.
Some example applications include:
• Date/Lot code inspections
• Label inspections
• Part etching inspections
• Part orientation inspections
