RT-VLOG - 振弦数据采集器
返回
RT-VLOG 是一款坚固、经济、紧凑且用户友好的数据采集器，设计用于监测市场上所有拔弦式振弦传感器。
RT-VLOG 是一款坚固、经济、紧凑且用户友好的数据采集器，设计用于监测市场上所有拔弦式振弦传感器。
新型 RT-VLOG 是一款高精度、坚固、紧凑且经济实惠的振弦（VW）数据采集器，设计用于监测多层渗压计、荷载盒和多点位移计。提供 4 或 8 通道配置，RT-VLOG 非常适合中小型项目。
其非易失性存储器可存储超过 63,500 条记录。每条记录包括带时间和日期的振弦读数和温度读数。存储器满时，记录停止或覆盖最旧的记录。存储在存储器中的数据可通过 USB 电缆轻松以 Hz 和工程单位在笔记本电脑上检索。记录管理器软件将所有读数保存在文本文件（CSV）中，可轻松导入电子表格软件。
RT-VLOG 设置简单，无需编程。可选 RS-232 串行连接可用于 IP 调制解调器、WIFI 串行服务器等。4 和 8 通道版本均可选配内置 900MHz Hermes 无线电，以无线方式传输数据。
数据采集器安装在防水的 IP 68 防护等级外壳中，配有用于信号电缆布线的电缆格兰头。未使用的电缆格兰头提供塞子。
在中等温度和假设每小时读数的条件下，一节锂电池 D 型电池为 4 通道数据采集器提供 9 年电力，为 8 通道 RT-VLOG 提供超过 6 年电力。额外容量电池选项（3 节额外锂电池）可在极寒天气下延长电池寿命。
