产品概述

The DS1922L-F5# from Maxim Integrated Products is an iButton® temperature logger with 8KB datalog memory in F5 Can package. This rugged, self-sufficient system measures temperature and record the result in a protected memory section. The recording is done at a user-defined rate. A total of 8192 8bit readings or 4096 16bit readings, taken at equidistant intervals ranging from 1s to 273hr, can be stored. Additionally, 512bytes of SRAM store application specific information and 64bytes store calibration data. A mission to collect data can be programmed to begin immediately, after a user-defined delay or after a temperature alarm. Access to memory and control functions can be password protected. The DS1922L is configured and communicate with a host-computing device through serial 1-Wire® protocol which requires only a single data lead and a ground return. Each DS1922L is factory lasered with a unique 64bit registration number that allows for absolute traceability.
  • Temperature accuracy of ±0.5°C from -10°C to +65°C
  • Measures temperature with 8bit (0.5°C) or 11bit (0.0625°C) resolution
  • Operating temperature range from -40°C to +85°C
  • Automatically wakes up measures temperature and stores values in 8KB of data-log memory
  • Programmable high and low trip points for temperature alarms
  • Programmable recording start delay after elapsed time or upon a temperature alarm trip point
  • Two-level password protection of all memory and configuration registers
  • Individually calibrated in a NIST-traceable chamber, complies to standard EN12830
  • Rugged construction survives harsh environments
  • Simple serial port interfaces to most microcontrollers for rapid data transfer
