Key Features
• Automatically Wakes up, Measures Temperature and Stores Values in 8kB of Datalog Memory in 8- or 16-Bit Format • Digital Thermometer Measures Temperature with 8-Bit (0.5°C) or 11-Bit (0.0625°C) Resolution • Accuracy of ±0.5°C from +20°C to +75°C • Water resistant or water proof if placed inside DS9107 iButton capsule • Sampling Rate from 1s up to 273hrs • Programmable Recording Start Delay After Elapsed Time or Upon a Temperature Alarm Trip Point • Programmable High and Low Trip Points for Temperature Alarms • Quick Access to Alarmed Devices Through 1-Wire Conditional Search Function • 512 Bytes of General-Purpose Plus 64 Bytes of Calibration Memory • Two-Level Password Protection of All Memory and Configuration Registers • Communicates to Host with a Single Digital Signal at up to 15.4kbps at Standard Speed or up to 125kbps inOverdrive Mode Using 1-Wire Protocol • Operating Range: 0°C to +125°C
• NIST Traceable Common iButton Features
• Digital Identification and Information by Momentary Contact. • Unique, Factory-Lasered and Tested 64-Bit Registration Number (8-Bit Family Code + 48-Bit Serial Number + 8-Bit CRC Tester) - Assures Absolute Traceability Because no Two Parts are alike. • Multidrop Controller for 1-Wire Net. • Chip-Based Data Carrier Compactly Stores Information. • Data Can be Accessed While Affixed to Object. • Button Shape is Self-Aligning with Cup-Shaped Probes. • Durable Stainless Steel Case Engraved with Registration Number Withstands Harsh Environments. • Easily Affixed with Self-Stick Adhesive Backing, Latched by its Flange, or Locked with a Ring Pressed Onto its Rim. • Presence Detector Acknowledges When Reader First Applies Voltage. • Meets UL#913 (4th Edit.). Intrinsically Safe Apparatus: Approved Under Entity Concept for Use in Class I, Division 1, Group A, B, C and D Locations (application pending). The DS1922T 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 DS1922T is config…
