  • Excellent memory space
  • Light in weight
  • Compatible with different instruments

DESCRIPTION:

The DS1921G Thermochron 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, both as a direct storage of temperature values as well as in the form of a histogram. Up to 2048 temperature values taken at equidistant intervals ranging from 1 to 255 minutes can be stored. The histogram provides 63 data bins with a resolution of 2.0oC. If the temperature leaves a user-programmable range, the DS1921G will also record when this happened, for how long the temperature stayed outside the permitted range, and if the temperature was too high or too low. An additional 512 bytes of read/write NV memory allow storing information pertaining to the object to which the DS1921G is associated. Data is transferred serially via the 1-Wire protocol, which requires only a single data lead and a ground return. Every DS1921G is factory-lasered with a guaranteed unique electrically readable 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 DS1921G to be mounted on almost any object, including containers, pallets, and bags.

FEATURES: 

  • Digital thermometer measures temperature 0.5oC increments
  • Accuracy +1oC from -30oC to +70oC. See EC table for accuracy specification
  • Built-in real-time clock (RTC) and timer has accuracy of +2 minutes per month per month from 0oC to 45oC
  • Water resistant of waterproof if placed inside DS9107 iButton capsule (Exceeds Water Resistant 3 ATM requirements).
  • Automatically wakes up and measures temperature at user-programmable intervals from 1 to 255 minutes.
  • Logs up to 2048 consecutive temperature measurements in protected nonvolatile (NV) random access memory.
  • Records a long-term temperature histogram with 2.0oC resolution.
  • Programmable temperature-high and temperature-low alarm trip points.
  • Records up to 24 time stamps and durations when temperature leaves the range specified by the trip points.
  • 512 bytes of general-purpose read/write NV random access memory
  • Communicates to host with a single digital signal at 15.4kbits or 125kbits per second using 1-Wire protocol.
  • 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
  • Multi drop 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, 5th Ed., Rev. 1997-02-24; Intrinsically Safe Apparatus, Approved under Entity Concept for use in Class I, Division 1, Group A, B, C, and D Locations
