Smartrac Technology Group, a provider of in RFID products and Internet of Things (IoT) solutions, has announced the launch of its Glass Tag Thermosensor product. The low-frequency RFID transponder offers temperature-sensing and identification capabilities for a variety of industrial items and animals, according to the company.
The Glass Tag Thermosensor, the latest addition to Smartrac’s LF Glass Tag product range, is suitable for implants and for use in liquids and vacuums. Its biocompatible glass capsule can withstand high-temperature or high-acidity conditions and other demanding industrial environments. It thus covers the application areas of existing Glass Tag products, the firm reports, while providing accurate and reliable temperature sensing and storing without the need for a dedicated battery-powered sensor or data logger.
In cold chain or industrial environments, this passive sensing product can wirelessly measure the temperature inside closed bins, jars or chambers, Smartrac indicates, whether the items to be monitored are in manufacturing facilities, laboratories or containers in transit. Similarly, pet owners and laboratory operators can identify animals and monitor their body temperature.
The only precondition, Smartrac notes, is the availability of a reader that can display the temperature information provided by the Excelio EL9265 IC. The chip offers 2048 bits of EEPROM, including 1,760 bits of user memory that can be used for storing up to 50 temperature measurements. Systems integrator customers receive information to calibrate, calculate and display the temperature in the readers they use.
The tag has an overall operating temperature of -25 degrees to +85 degrees Celsius and a storage temperature of -40 degrees to +85 degrees. The product allows user-specific calibration of the preferred temperature range for improved accuracy, which can be as high as ±0.05 degrees.
“With the new Glass Tag Thermosensor, we are combining two of Smartrac’s particular strengths: experience in developing durable and very reliable glass transponders and our expertise in passive (no-battery) single-chip sensor solutions,” said Robert Blaschke, Smartrac’s director of business line animal ID components, in a prepared statement. “[The] Glass Tag Thermosensor provides the market with the superior identification and temperature measurement capabilities it has been asking for.”
The tag is available for volume delivery with a form factor of 2.12 millimeters by 12 millimeters, two frequency options (134.2 kHz and 125 kHz for industrial applications), several personalization options (e.g. ISO 11784/85), and an optional Parylene coating. Volume delivery is expected to begin this month. Smartrac is in the process of being acquired by Avery Dennison, and the new tag will be among the products Avery will then own.
