PM891AK02规格型号安装规范如下ABB2、频率选择在“80Hz”。在校准传感器时，一般应将频率定在80Hz。也可将频率置于其它频率位置校准传感器。
3、“功能选择”开关置于“速度”位置。  将“增益调节”电位器调至zui小；电源开关置于“开”。4、调节“输出电压”电位器，使校准仪振动速度输出幅值为10（mm/S）。                                  

此时，显示窗显示为：10.0mm/s。5、数字电压表测量被测传感器的输出电压。根据被测传感器的输出电压（实测值），即可计算出此传感器的误差。* 标准值是由被测传感器的灵敏度电压所决定的。例如： 传感器的灵敏度为200mV/cm/S，则它的输出电压(标准值)即为200mV。

   传感器的灵敏度为280mV/cm/S，则它的输出电压(标准值)即为280mV。

 当被校准的传感器为水平传感器时，校准仪应水平放置。

   当被校准的传感器为垂直传感器时，校准仪应垂直放置。

TD-2-50TD-2型热膨胀传感器

TD-2型热膨胀传感器主要用于测量汽轮机汽缸膨胀位移量，与热膨胀监控仪相配合即可完成热膨胀位移量的远传指示、报警、恒流输出等功能。就地指示视野大，远传指示为数字显示，清晰直观。采用中频差动变压器式位移传感器作为传感元件，是一种高可靠的 LVDT 位移传感器，抗力强，线性好，结构简单，不易损坏，能连续使用。 

振动速度传感器是利用磁电感应原理把振动信号转换成电信号。它主要由磁路系统、线圈组件、弹簧阻尼等部分组成。在传感器壳体中刚性地固定有两个线圈组件，磁钢用弹簧悬挂于壳体。当传感器在工作频率范围内工作时，线圈与磁钢产生相对运动，线圈切割磁力线，产生感应电动势（感应电压），该电压正比于机壳的振动速度。温度传感器的温度测量是利用铂电阻随温度线性变化的性质来测温的。
2. The frequency is selected at "80Hz".



When calibrating the sensor, the frequency should generally be set at 80Hz.



The sensor can also be calibrated by placing the frequency at other frequency positions.



3. Set the "Function Selection" switch to the "Speed" position. Adjust the "gain adjustment" potentiometer to zui small; Power Supply



Switch to ON.



4. Adjust the "output voltage" potentiometer so that the output amplitude of the vibration speed of the calibrator is 10 (mm/S). At this time, the display window displays 10.0mm/s.



5. The digital voltmeter measures the output voltage of the sensor under test.



According to the output voltage (measured value) of the measured sensor, the error of the sensor can be calculated.





*The standard value is determined by the sensitivity voltage of the measured sensor.



For example:



If the sensitivity of the sensor is 200mV/cm/S, its output voltage (standard value) is 200mV.



If the sensitivity of the sensor is 280mV/cm/S, its output voltage (standard value) is 280mV.



When the calibrated sensor is a horizontal sensor, the calibrator shall be placed horizontally.



When the calibrated sensor is a vertical sensor, the calibrator shall be placed vertically.



TD-2-50TD-2 Thermal Expansion Sensor



TD-2 thermal expansion sensor is mainly used to measure the expansion displacement of steam turbine cylinder, and it can complete remote indication, alarm, constant current output and other functions of thermal expansion displacement with the thermal expansion monitor. The field of vision of local indication is large, and the remote indication is digital display, which is clear and intuitive. The medium frequency differential transformer displacement sensor is used as the sensing element. It is a highly reliable LVDT displacement sensor with strong resistance, good linearity, simple structure, and is not easy to be damaged. It can be used continuously.



The vibration speed sensor uses the principle of magnetoelectric induction to convert the vibration signal into electrical signal. It is mainly composed of magnetic circuit system, coil assembly, spring damping, etc. Two coil assemblies are rigidly fixed in the sensor housing, and the magnetic steel is suspended on the housing with a spring. When the sensor works within the operating frequency range, the coil and the magnetic steel produce relative motion, the coil cuts the magnetic line of force, and generates an induced electromotive force (induced voltage), which is proportional to the vibration speed of the casing. The temperature measurement of temperature sensor is based on the property that platinum resistance changes linearly with temperature.
