2 SYSTEM DESCRIPTION 系统描述
2.1 SYSTEM DESCRIPTION 系统概述
ViscoSense®2 is, besides other applications, intended for use in fuel oil treatment systems to obtain
a correct measurement and control of the fuel oil viscosity.
扭转振动黏度计ViscoSense®2 既是应用于燃油处理系统以期对燃油的粘度进行准确测量及调控
Figure 1 shows a typical fuel treatment system with return line from the engine. In this system, the
degassing/mixing tank operates as a fuel buffer, ensuring gradual changes of viscosity which results
in a stable control of the viscosity. The ViscoSense®2 sensor is used to measure the actual viscosity
of the fuel oil. The signal from the sensor is compared to the setpoint of a viscosity controller, which
regulates the output of the fuel heater via a control element (steam or thermal oil valve, or electric
heater cabinet).

料缓冲器的作用以确保黏度渐变，从而获得对黏度的稳定控制。控制系统对黏度传感器发出的信号与
控制器的设定值进行比较，通过控制元件[蒸汽，热油阀或电热器]以调节加热器的输出

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。

2.3 PRINCIPLE OF OPERATION 操作原理
The patented measuring principle is based on rotational vibration of a pendulum in liquid.
已获得专利权的测量原理系以传感器探头在流体中的旋转振动为基础
The sensor consists of a sensor head (1) attached to a base plate (2) by a torsion tube (3). Two sets
of piezo-electric elements (4) are positioned inside the pendulum. One set drives the pendulum, the
other set measures and controls the rotational movement of the pendulum via a feedback circuit. In
this way the pendulum is kept in vibration at its resonance frequency.
传感器系由通过扭管(3)固定在基座(2)上的钟摆(1)组成。钟摆内置两套压电陶瓷元件(4)。一套驱动钟
摆，而另一套通过反馈信号测量和控制钟摆的旋转动作。这样使钟摆在其共振频率上保持振动。
Measuring the resulting frequency at two specific values of phase difference, yields a value for the
damping which is proportional to the square root of the dynamic viscosity.
测量相位差两点的频率，得出衰减值。这一数值与动力黏度的平方根成正比。
A flow tube (5) is placed around the pendulum, to protect it against mechanical damage.
流管(5)被置于钟摆外围，以保护钟摆避免机械损坏。
The flowtube is machined with a smooth surface, as well as with a triplet of oval slits. These slits
increase the refreshing rate between sensor and flowtube.
流管经过精细机加工处理，表面光滑并有三个椭圆形开口。这些开口增加了传感器探头和流管之间的
更新速率。
