2.2 SYSTEM COMPONENTS
系统组成部分
The ViscoSense
®
2 viscosity system consists of:
扭转振动黏度测量系统包括

the combined viscosity and temperature measuring sensor
黏度及温度测量传感器

the sensor housing
传感器安放室

Interface box
界面盒
The sensor housing is made of ductile iron and has flanges for direct mounting in the fuel line. The
sensor itself is made of stainless steel and is mounted in the housing. The sensor head has a
special Teflon
®
coating and it is mechanically protected by a stainless steel flowtube with 3 oval slits.
It is supplied with 5 metres of signal cable for connection to the interface box. The ViscoSense
®
2
Interface box is a wall mount electronic unit, processing the signals from and to the sensor. It
provides 4..20 mA signals for remote read-out of viscosity and temperature for a controller or other
system elements. See separate technical manuals for a description of these components.
传感器安放仓室由球墨铸铁制成，其两侧连接法兰便于直接在管路中安装。传感器本身由不锈钢制
成，安放在仓室中。传感器探头的表面经过特富龙
®
特殊处理，并且受到其上有三个椭圆形开口的不
锈钢流管的机械保护。传感器自带
5
米长的信号电缆用于与界面接口盒之间联接。第二代
ViscoSense
®
传感器界面盒系壁式安放电子装置，加工处理来自及传送至传感器的信号。输出
4-20mA
电流信号用
于控制器或其他系统组件远程温度黏度显示。请分别参阅这些部分的专门技术手册。
