Analog Devices / Maxim Integrated DS1925 Thermochron iButton® Temperature Logger

Analog Devices DS1925 Thermochron iButton® Temperature Logger is a rugged, self-sufficient system that measures temperature and records the result in a protected memory section. The recording is done at a user-defined rate. A total of 122K 8-bit readings or 61K 16-bit readings taken at equidistant intervals ranging from 5min to 273hrs can be stored. In addition, there are 512 bytes of nonvolatile memory for storing application-specific information. A mission to collect data can be programmed to begin immediately, after a user-defined delay, or after a temperature alarm. Access to the memory and control functions can be password protected. The Analog Devices DS1925 Thermochron iButton Temperature Logger is configured to and communicates with a host computing device through the serial 1-Wire® protocol, which requires only a single data lead and a ground return.

Features

  • Provides high-quality temperature exposure assessment of an end product
    • ±0.5°C temperature measurement accuracy of with storage for up to 125,440 timestamped values
    • Flexibility to monitor and data-log long-duration exposures with short-duration time intervals
    • Unique factory-lasered 64-bit serial number ensures absolute traceability because no two parts are alike
  • Highly configurable options for data logging and security
    • Programmable sample rates from 5 minutes to 273 hours
    • Programmable recording start delay after elapsed time or upon a temperature alarm trip point
    • Two-level password protection of all memory and configuration registers
    • Measure and report internal battery level and output-logged data if a battery is depleted
  • Physically robust, operationally efficient
    • Durable stainless-steel enclosure withstands harsh environments and conditions
    • Communicates to a host system with the single-contact 1-wire interface
    • -40°C to +85°C operating temperature range

Applications

  • Bioscience
  • Food safety
  • Pharmaceutical and medical products
  • High-temperature logging (process monitoring, industrial monitoring)
  • Temperature logging in cold chain
