DS1922L Temperature logger with button with 8KB data logging memory
description
DS1922L/T Temperature Record My button ® is a rugged, self-contained system that measures temperature and records 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-bit readings can be stored at intervals ranging from 1 second to 273hrs. In addition to this, there is also 512 bytes of SRAM, which is used to store 64 bytes of application-specific information and calibration data. A data acquisition task that can be programmed immediately, or after a user-defined delay, or after a temperature alarm. Access to memory and control functions, can be password protected. Configure and communicate host computing devices for DS1922L/T via the serial line ® protocol, requiring only one data line and a return ground wire. Each DS1922L/T is guaranteed by the factory lithography to be 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. Accessories enable DS1922L/T to be installed on almost any object, including containers, pallets, bags. 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.
Key features:
- Automatic wake-up, measurement temperature and 8KB data logging stored values in 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
- Accuracy ± 0.5°C from -10°C to +65°C (DS1922L) and ± 0.5°C between +20°C and +75°C (DS1922T) with software correction
- Waterproof or waterproof if placed inside DS9107 I Button Capsule (waterproof more than 3 ATM requirement)
- Sampling rates from 1 second to 273hrs
- Programmable recording starts delayed after elapsed time or at the temperature alarm trigger point
- Programmable high and low temperature alarm trigger points
- Astonished devices, with quick access via the 1-Wire conditional search function
- 512 bytes of universal plus 64 bytes of calibration memory
- Two levels of password protect all memory and configuration registers
- The communication hosts a digital signal at standard speeds up to 15.4kbps or up to 125kbps in high-speed mode using the 1-Wire protocol
- Business scope: DS1922L: -40 to +85°C; DS1922T: 0 to +125°C
-
Compliant with UL 913, Fifth Edition, Revised February 24, 1997. Intrinsically safe equipment, approved for use under the entity concept of Class I, Zone 1, Groups A, B, C, D zones

Applications/Uses:
-
Environmental and Thermal Management Systems (HVAC)
-
Temperature monitoring for humans and animals.
-
The process requires the temperature to be close to the boiling point of water (DS1922T only), such as pasteurized food items, monitoring.
-
Monitoring of refrigeration systems.
- Transportation and storage of critical temperature products, such as fresh produce, pharmaceuticals, blood products.
