Optical sensors are easy to set up, easy to use
The new B45 series of intelligent optical sensors from ABB Control is designed to offer maximum versatility and ease of use for a wide variety of control applications.
Flexible bar code scanner designed to adapt
Thanks to the Adaptascan's autofocus capability and WindowsT-based configuration software, changes in focus, scan pattern, label format and communication requirements can be made on-line.
A low-cost reversible label applied to the shipping carton or pail of confectionery and other temperature-sensitive foods allows QC managers to verify cold storage conditions.
These reversible labels use a liquid crystal thermometer that indicates current temperature on the "green bar" section of the label.
Reversible labels are also used in the medical diagnostics industry to indicate temperature of specimens en route for laboratory analysis.
Dry Pak Industries offers irreversible labels that monitor conditions from -30 to +300C, as well as labels and tags that indicate how long a product has been exposed above critical temperatures.
WarmMark and ColdMark time temp tags, used to monitor temperature during shipping and storage, are designed with three windows on the tag.
Windows turn a tell-tale red as a product is exposed over or under critical temperatures for a brief time (30 minutes), a moderate time (2 hours) or a prolonged time (2 days).
Typically placed on the outside of a pallet, irreversible tags and labels monitor temperature conditions as a product moves through the distribution system; up to 40,000 pounds of product can be monitored for less than US $20.
A full line of strip-chart temperature recorders from Dry Pak Industries provides inexpensive yet reliable continuous monitoring of temperatures while products are in transit.
Placed inside a cargo container at the beginning of shipment, these disposable recorders produce a printed chart of temperature variation once the shipment reaches its destination.
In-transit strip-chart temperature recorders are available in several run times from 5 to 60 days.
