6.4.1 ViscoSense
®
2 interface box
传感器界面盒
1. Install the ViscoSense
®
2 interface box in a suitable location, free from excessive vibrations,
humidity and excessive temperature variations.
界面盒应安放在适合的地方，避免过渡振动以及
温湿度变化。
2. The maximum distance between sensor and the interface box is determined by the cable length
from the sensor, being approx. 5 metres.
传感器与界面盒之间的距离是由传感器电缆长度决定
的，大约
5
米。
3. Allow sufficient space for installation of cables and for servicing.
留有充分空间以便安装电缆和服
务需要。

2 housing
传感器安放室
1. Remove dust caps from sensor housing and install housing stress-free, with shutoff valves and
bypass valve in the fuel piping as illustrated in Figure 6. Take care that the flow direction is in
accordance with the indication on the housing (inlet, outlet and arrow) as illustrated in figure 8.
Support inlet and outlet piping sufficiently.

2. Note that the distance between fuel heater and sensor housing inlet should not exceed 4 metres.
注意：燃油加热器与探头安放仓室入口间的距离不应超过
4
米。
3. To protect the instrument from excessive vibrations, which can cause malfunctioning of the
instrument, it is recommended to:
为防止仪器因过渡振动引起的误操作，建议：
Install the ViscoSense
®
2 as low as possible in the fuel system close to a solid structure or
beam.
在燃油系统中尽可能低的安装传感器，并靠近稳固结构或梁。
Install suitable pipe clamps at both sides of the ViscoSense
®
2 sensor.
在传感器两侧安装适当的管夹。
4. Allow at least 50 cm clearance to the sensor housing, to be able to take out the measuring sensor
for service.
预留至少
50
公分距离，以便于维修服务时取出探头。
