温度数据记录器DCX-22系列

压力 水位 RS-485.

自主数据收集器100％防水DCX-22是一种自主，电池供电的仪器，由不锈钢制成，设计用于在长时间记录水深（压力）和温度。提供两种版本：DCX-22传感器，电子和电池容纳在密封的不锈钢管中，用于潜水部署。对于数据读出的数据，必须从测量点恢复DCX-22。然后移除O形圈密封端盖以访问数据端口。DCX-22使用绝对压力传感器。在应考虑气压变化的影响的浅水深度中，建议将第二数据集电极DCX-22（Baro）放置在表面，以记录气压。然后PC计算差压率。通过减去两个测量值来进行水深。DCX-22 SG / VG该传感器通过防水电缆连接到带有数据读出口的表面安装外壳。这种安排允许更容易地从固定安装恢复。 The DCX-22 SG/VG does not have to be removed from the dip pipe for data read out. The DCX-22 SG/VG is supplied with a 2” diameter fixing plate to enable mounting at the top of the dip pipe. The sensor can be sealed gauge SG, or vented gauge VG, the cable carries the vent tube for VG version sensors, vent port in the housing is protected by a breathable Gore-Tex® membrane. The electronics employ the latest microprocessor technology, which give high accuracy and resolution for the pressure and temperature signals from both the depth sensor and the barometric sensor.
