Product Introduction

overview
iButton&reg;The temperature recorder (DS1922L/T) is a sturdy and durable self powered system that can measure temperature and record the measurement results in a protected memory. The frequency of recording temperature is defined by the user. A total of 8192 8-bit data records or 4096 16 bit data records can be saved, which are collected at equal intervals ranging from 1 second to 273 hours. In addition, there is a 512 byte SRAM used to store specific application information, and 64 bytes used to store calibration data. A data collection task can be programmed to start immediately, or after a user-defined delay, or after a temperature alarm. Access to memory and control functions can be password protected. DS1922L/T via serial 1-Wire® The protocol communicates with the host, requiring only a single data lead and return ground. Each DS1922L/T is factory etched with a unique 64 bit registration number to ensure absolute traceability of each device. The sturdy stainless steel packaging has high resistance to various harsh environments, such as contamination, moisture, and impact. The various accessories provided can enable the DS1922L/T to be installed on almost any object, including containers, shelves, or bags.

When calibrating and certifying iButton data loggers with NIST traceable reference devices, Maxim's online program can generate valid certification documents for DS1922L/T data loggers. Enter an iButton serial number (or a set of serial numbers) to obtain a valid authentication document generated in PDF format.
