Product Introduction

DS1922E Temperature logger

Key features:

Automatically wake up, measure temperature, and store values in 8KB data logging memory in 8-bit or 16-bit format
The digital thermometer measures temperature with 8-bit (0.5°C) or 11-bit (0.0625°C) resolution
Temperature control accuracy: ±1.5°C from +110°C to +140°C, ±7°C typical between +15°C and +110°C
Waterproof or waterproof if DS9107 I button capsule placed inside (waterproof more than 3 ATM required)
The sampling rate ranges from 1 second to 273hr
Programmable high and low temperature alarm trigger points
Programmable recording starts delayed after elapsed time or at the temperature alarm trigger point
Astonished devices, with quick access via the 1-Wire conditional search function
576 bytes of universal memory
Two levels of password protect all memory and configuration registers
A digital signal communicates with the host at standard speeds up to 15.4kbps or up to 125kbps in high-speed mode using the 1-Wire protocol
Operating temperature range: +15°C to +140°C

Applications/Uses:

Stand-alone high-temperature measurement and recording applications
Applications of steam sterilization

description

The i-Button DS1922E Temperature Logger is a robust, self-contained system that measures temperature and records the results in a protected memory section. When the recording is complete, at a user-defined rate. A total of 8,192 8-digit readings or 4,096 16-digit readings can be stored at intervals ranging from 1 second to 273hr. In addition, 576 bytes of SRAM store application-specific information. A data acquisition task that can be programmed immediately after a user-defined delay, or after a temperature alarm. Access to memory and control functions, can be password protected. DS1922E is to use a serial line ® protocol with the host, only one data line and return ground line are needed to configure and communicate with the computing device. Each DS1922E factory lithography guarantees a unique 64-digit registration number, which is absolutely traceable. Durable stainless steel enclosure with high resistance to environmental hazards such as dust, moisture and impact.

While all I-button data loggers are NIST traceable reference device calibration/validation, Maxim provides a web application that generates a validation certificate for the DS1922L/T data logger. The input is the I button registration number (or numeric list) and the output is a verification certificate in PDF format.
