Track displacement with optical detection Optical displacement sensors serve measurement jobs well. Optical measurements are often practical and quick, sometimes comparable to measurement by laser sensor.

I recommend:  Micro-Epsilon carries a triangulating laser, as well as optical displacement sensors. They also carry many other types of measuring and positioning devices, including the charge coupled device (CCD) sensor. Philtec distributes optical displacement sensors for distance, displacement and vibration measurement and its website contains quite a bit of optical sensors information.

Locate optical sensors that measure dissolved oxygen Sometimes divers and biologists prefer the newer optical technology that requires relatively less care than electrode-based DO sensors. For instance, some conventional sensors have more variables because of changes in the electrolyte fluid during heavy use. Also, optical sensors often work better in stagnant water.

I recommend:  AADI specializes in oceanic science and has many quality sensors, including the optical dissolved oxygen sensor. Another source is Global Water Instrumentation, Inc. which carries a model that features long life and bio-fouling resistance. Their unit is unaffected by water current or a lack thereof.

Experiment with optical sensors to monitor packaging or sort batches Optical color sensors are excellent for sorting batches, like bricks; and keeping consistency between batches, like beverages. They also help perform quality control of your packaging.

I recommend:  Pepperl+Fuchs, Inc. carries many types of photoelectric sensors, including optical color and contrast sorting sensors. Avago Technologies is another source for an optical fiber sensor for color. They have a number of red, green, blue (RGB) products, including four-channel color sensors suitable for quality control applications.
