以计算机为基础的气象系统的设计 数据存储和真正解决方案- “界面友好” 监测的气候条件。这 标准包装包括: 风速风向 空气温度; 相对湿度 气压; 降水 数据采集仪 及三脚架和桅杆 电池和电池充电器 选配探头: 太阳能辐射传感器、土壤和水温度传感器, 土壤水分蒸发传感器。 The unique modular system design provides plug-and-play functionality for adding or replacing sensors. The T9M260278 Data Acquisition Module includes the following features larger nonvolatile memory, selectable averaging intervals, 12 bit analog conversion, 0.1% F.S. accuracy, two alarm outputs, and ptional modem communications. o The T9M260278 is supplied with an attractive desktop data acquisition module with a memory capacity of 128KB RAM (approximay 45 days at 15 minute intervals with 6 sensors). The standard system includes a 120Vac power adapter and RS232 serial port for connection to a personal computer. For outdoor or remote applications, two enclosure options are available. One is for sites with AC power and the other utilizes a solar panel. Both options include a NEMA-4X enclosure and rechargeable battery to allow continued operation in the event of power failure. Data can be viewed using Windows HyperTerminal or other terminal programs such as Procomm. A one page real-time text display or an ASCII row and column format may be selected. A menu is provided for setting the date and time, alarms, logging interval etc. Optional graphical displays software is available for viewing real-time and historical data charts and graphs. Data Acquisition Module Reporting units: English or Metric, all measurements Operating power: 10-16 Vdc Power consumption: 60 mA maximum Serial port: 9-pin d-sub connector, selectable baud rate, flow control Memory: 128KB RAM, nonvolatile (45 days at 15 minute intervals with 6 sensors) Expandable to 256KB or 512KB.
