Ensure High-Quality Sensors
Sensors test for temperature, humidity, color, text, and bar codes to protect the quality and ensure the consistency of a product.
Sensors and inspection systems provide invaluable services to pharmaceutical and medical device companies. Not only can they check label placement, bar codes, and consistency, they can also monitor the environment of the package during shipping and storage. Manufacturers of sensors keep the user firmly in mind when designing their products—specialized software and easy-to-read displays allow easy access to data.

A photoelectric sensor detects the presence or absence and the basic position of a label on a glass or plastic container, regardless of color. The E3S-CD diffuse photoelectric sensor focuses on whether the label itself, rather than the container, is in a predetermined location. The configuration of its beam-splitting optics allows the unit to detect labels of varying color and luster. Omron Electronics Inc., Schaumburg, IL.
Ultrasonic sensors offer four different sensing ranges from 102 to 1016 mm. The Model SM800 flat-profile series of microprocessor-based, through-beam sensors reliably perform a variety of sensing functions.

Hyde Park Electronics Inc., Dayton, OH.
A range of ultrasonic industrial position sensors features analog output and teach mode. These sensors offer simple, one-button programming and require no special tools for setup. Operating range is 100–700 mm. Applications for the multifunction sensors include web tension or breakage control, monitoring roll diameters, and measuring. Baumer Electric Ltd., Southington, CT.
An empty bottle inspection system examines returnable and nonreturnable glass bottles. The Linatronic conducts complex bottle inspections at the base, neck, and sidewalls for proper height, size, shape, color, and condition, rejecting unsuitable bottles. Other functions of the in-line machine include inspecting for chipped glass, clear and opaque foreign substances, residual liquids, and glass imperfections. Krones Inc., Franklin, WI.
A dual-temperature recorder provides a permanent visual record of damaging temperature conditions for transit and storage of temperature-sensitive goods such as pharmaceuticals and medical devices. The ColdSnap+ consists of a bimetallic sensing element that snaps at a predetermined temperature, turning a "low temp" indicator window bright red when the temperature goes below a predetermined cold set point. When the temperature rises above a predetermined hot set point, a "hot" indicator window turns from silver to black. Telatemp Corp., Fullerton, CA.
Thermohygrometric instruments can detect temperature and humidity in controlled environments such as cleanrooms, pharmaceutical packaging areas, medical device manufacturing and storage areas, and testing laboratories.
