DS1921H-F5 (wysoka rozdzielczość, pomiar od +15°C do +46°C) DS1921Z-F5 (wysoka rozdzielczość, pomiar od -5°C do +26°C)
Opis
The DS1921H/Z Thermochron® iButtons® are rugged, self-sufficient systems that measure temperature and record 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 64 data bins with a resolution of 0.5°C. If the temperature leaves a user-programmable range, the DS1921H/Z 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. Additional 512 bytes of general-purpose battery-backed SRAM allow storing information pertaining to the object to which the DS1921H/Z is associated. Data is transferred serially via the 1-Wire® protocol, which requires only a single data lead and a ground return. Every DS1921H/Z 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 DS1921H/Z to be mounted on almost any object, including containers, pallets, and bags.

DS1922E-F5 (wysoka pojemność, pomiar od +15°C do +140°C)
Opis
The DS1922E temperature logger 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. A total of 8192 8-bit readings or 4096 16-bit readings, taken at equidistant intervals ranging from 1s to 273hr, can be stored. Additionally, 576 bytes of SRAM store application-specific information. A mission to collect data can be programmed to begin immediately, after a user-defined delay, or after a temperature alarm. Access to the memory and control functions can be password protected. The DS1922E 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 DS1922E 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. While all iButton data loggers are calibrated/validated against NIST traceable reference devices, Maxim offers a web application to generate validation certificates for the DS1922L/T data loggers. Input is an iButton registration number (or list of numbers) and the output is a validation certificate in PDF format.
Właściwości:
- Automatically Wakes Up, Measures Temperature, and Stores Values in 8KB of Data-Log Memory in 8- or 16-Bit Format
- Digital Thermometer Measures Temperature with 8-Bit (0.5°C) or 11-Bit (0.0625°C) Resolution
- Temperature Accuracy: ±1.5°C from +110°C to +140°C, ±7°C typical from +15°C to +110°C
- Water Resistant or Waterproof if Placed Inside DS9107 iButton Capsule (Exceeds Water Resistant 3 ATM Requirements)
- Sampling Rate from 1s Up to 273hr
- Programmable High and Low Trip Points for Temperature Alarms
- Programmable Recording Start Delay After Elapsed Time or Upon a Temperature Alarm Trip Point
- Quick Access to Alarmed Devices Through 1-Wire Conditional Search Function
- 576 Bytes of General-Purpose Memory
- Two-Level Password Protection of All Memory and Configuration Registers
- Communicates to Host with a Single Digital Signal Up to 15.4kbps at Standard Speed or Up to 125kbps in Overdrive Mode Using 1-Wire Protocol
- Operating Temperature Range: +15°C to +140°C
