| Description |
The DS1922L/T temperature logger iButtons® are rugged, self-sufficient systems that measure temperature and record the result in a protected memory section. The recording is done at a user-defined rate. A total of 8192 8-bit readings or 4096 16-bit readings taken at equidistant intervals ranging from 1s to 273hrs can be stored. In addition to this, there are 512 bytes of SRAM for storing application-specific information and 64 bytes for calibration data. A mission to collect data can be programmed to begin immediately, or after a user-defined delay or after a temperature alarm. Access to the memory and control functions can be password protected. The DS1922L/T is configured and communicates with a host computing device through the serial 1-Wire® protocol, which requires only a single data lead and a ground return. Every DS1922L/T is factory-lasered with a guaranteed unique 64-bit registration number that allows for absolute traceability. The durable stainless-steel package is highly resistant to environmental hazards such as dirt, moisture, and shock. Accessories permit the DS1922L/T to be mounted on almost any object, including containers, pallets, and bags.
While all iButton data loggers are calibrated/validated against NIST traceable reference devices, Maxim offers a web applicationto generate validation certificates for the DS1922L/T data loggers. Input is an iButton registration number (or list of numbers) and the output is a validation certificate in PDF format. |
This product contains lithium-metal batteries. See applicable regulations for transport requirements for batteries in equipment.
