The CR7 is a precision instrument that is primarily used in multi-parameter research and industrial applications. Each CR7 system is individually configured to meet the specific measurement needs of the customer.
This control module is the base of the measurement system, then the input/output module, data logger enclosure, and I/O cards are added. As measurement needs change from study to study, the CR7 can be adapted by modifying the I/O card configuration.
続きを読むThe CR700X control module is the main component in a CR7—a large modular data logger. It is ordered with internal PROMs (firmware) and temperature testing. The CR700X contains the system's CPU, ROM, RAM, a serial interface for communication with data storage/retrieval peripherals and connection of up to four I/O Modules (typically one alongside the CR700X and three at some distance to the CR700X), and a keyboard/display. Refer to the Configuration tab for software compatibility.
The CR700X also accommodates:
A complete CR7 consists of:

実用的な最大値は、データロガーの 2 つのCターミナルごとに 1 つのマルチプレクサを接続することです。Cターミナルをマルチプレクサ間で共有して、接続するマルチプレクサの数を増やすことができます。ただし、ターミナルを共有するには、より複雑な配線とプログラミングが必要です。2 つのCターミナルごとに 1 つ以上のマルチプレクサを接続したいユーザーは、Campbell Scientific の営業またはサポート エンジニアに問い合わせて支援を受けることをお勧めします。
