6.4.3 To assemble ViscoSense
®
2 sensor
如何安装传感器
1. Check the O-ring for damage, before installing the ViscoSense
®
2 sensor. Replace if necessary.
Make sure only one original o-ring is installed.
安装前查看密封圈是否受损，必要时进行更换。确保
只安装一个原装的密封圈。
2. Remove transport locking cap from bottom side of flowtube.
从流管底部拆除运输中防止残损的锁
定鞘
3. Please make sure not to damage the Teflon
®
coating during installation.
安装中杜绝损伤特氟龙
涂层。
Without the transport locking cap the sensor is not protected against excessive
mechanical shocks which can occur during handling.
注意： 没有锁定鞘，既无法保证探头在运输，装卸过程中可能受到的过度的机械振动
冲击影响。
4. Install sensor carefully in housing with the closed surface facing the flow, illustrated in figure 8.
小心地将探头置于安放仓室内，注意流管的封闭面朝向流动方向，参见图
8
。
Make sure the flow tube closed surface is pointing towards the inlet of the sensor
housing, see figure 8. The sensor will not work correctly if installed wrongly.
确保流管封闭面朝向探头安放仓室入口。不正确的安装会导致传感器无法正常工作。
Check if the position of the hole inside the housing and the fixation pin on the
sensor match
.
检查探头上用于固定的插头与安放室内的孔眼是否对位。
5. Tighten the nut (1) by hand. If there is a temperature difference between the sensor and the
housing you should wait until they have the same temperature before tightening the nut.
首先用手固定螺帽
(1)
。在紧固前若探头与仓室间有温差，则应等待直到两者温度相同为止。
6. Tighten the nut (1) with a wrench with a recommended torque of 100 Nm.
然后用螺旋钳在
100
牛顿米的扭转力矩下上紧螺帽
(1)
Make sure that all flange bolts and nuts are tightened correctly before re-pressurizing the
system.
确保所有连接法兰之螺钉螺帽在重新施压前已充分紧固。
