Key Features
• Automatically Wakes Up, Measures Temperature, and Stores Values in 8KB of Data-Log Memory in 8- or 16-Bit Format • Digital Thermometer Measures Temperature with 8-Bit (0.5°C) or 11-Bit (0.0625°C) Resolution • Temperature Accuracy: ±1.5°C from +110°C to +140°C, ±7°C typical from +15°C to +110°C • Water Resistant or Waterproof if Placed Inside DS9107 iButton Capsule (Exceeds Water Resistant 3 ATM Requirements) • Sampling Rate from 1s Up to 273hr • Programmable High and Low Trip Points for Temperature Alarms • Programmable Recording Start Delay After Elapsed Time or Upon a Temperature Alarm Trip Point • Quick Access to Alarmed Devices Through 1-Wire Conditional Search Function • 576 Bytes of General-Purpose Memory • Two-Level Password Protection of All Memory and Configuration Registers • Operating Temperature Range: +15°C to +140°C • Communicates to Host with a Single Digital Signal Up to 15.4kbps at Standard Speed or Up to 125kbps in Overdrive Mode Using 1-Wire Protocol
• 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 DS1922E temperature logger iButton 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 8192 8-bit readings or 4096 16-bit readings, taken at equidistant intervals ranging from 1s to 273hr, can be stored. Additionally, 576 bytes of SRAM store 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 protec…
