Model:DS1922L

Description

The DS1922L iButton® temperature logger is a rugged, self-sufficient system that measures temperature and records the result in a protected memory section. A total of 8192 8-bit readings or 4096 16-bit readings can be stored at recording intervals ranging from 1s to 273hrs. 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 DS1922L is configured and communicates with a host computing device through the serial 1-Wire® protocol, which requires only a single data lead and a ground return. Every DS1922L is factory-lasered with a guaranteed unique 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 DS1922L to be mounted on almost any object, including containers, pallets, and bags.

NOTE: Requires Software and adapter cable to communicate.

Features

Specifications

  • Memory Type: NVSRAM
  • Memory Size: 512 bytes
  • Data Logger Size: 8192 byte
  • Data Logger Sample Rate: 1s to 273 hours
  • Data Logger Accuracy: correctible to +/- 0.5°C
  • Data Logger Resolution: Selectable
    8-bit = 0.5°C
    11-bit = 0.0625°C
  • Measurement Range: -40 to +85°C
  • Thermal Response time: up to 130 seconds 
  • Security Features: password protected
  • Programmable Alarm: Temperature High/Low
  • Real Time Clock: Yes
  • RTC Accuracy: depends on temperature, @ 20’C drift ~ 1 minute/month.
  • Weight: 3.3g
  • Size: diameter 17.35 x 5.9mm
  • IP Rating: IP56
  • Battery Life: depends on number of factors such as Temperature and Logging rate. 
    E.g. 8-bit logging @ 20’C at 30 second intervals, the battery should last around 300 days. Record every 10 minutes in 8-bit mode @ 20’C, the battery should last around 5.5 years

Applications

  • Human and Animal Temperature Monitoring.
  • Environmental and Thermal Management Systems (HVAC)
  • Monitoring of refrigeration systems.
  • Temperature-Critical Product Shipping and Storage, such as Fresh Produce, Pharmaceuticals, and Blood Products.
  • Monitoring of processes that require temperatures close to the boiling point of water (DS1922T only), such as pasteurization of food items.
