被校准的速度传感器的输出导线与数字电压表连接。 2、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。 技术指标： 1. 量程： 0 ～50mm (量程由用户自定) 2. 准确度：± 1% (满量程) 3. 环境温度： -20 ℃ ～+100 ℃ 4. 相对湿度：≤ 80% 技术参数 1.振动传感器 灵 敏 度：30mV/mm/s 加 速 度：8g 测量范围：2mm 频率响应： 10~300Hz 2.温度传感器：PT100 测量范围：0～400℃ 3.环境温度：-10～100℃  4.测量方法：垂直、水平、轴向 5.固定螺孔：在Φ85的圆周上均匀分布用4个M8螺钉固定 6. 外形尺寸：Φ70mm×180mm 7.插入深度：83mm TD-2-50TD-2型热膨胀传感器TD-2-35 Thermal expansion transmitter It 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 XCW-R thermal expansion monitor.

TD-2 Thermal Expansion Travel Transmitter TD-2 type thermal expansion travel transmitter is equipped with various TD-2 type linear differential transformer sensors. The built-in excitation source and differential measurement circuit convert the thermal expansion on both sides of the casing into 4~20mA current output. The difference between the two represents the deformation of the casing. This deformation will cause huge stress between the casing and the foundation, resulting in misalignment. If the casing sliding pin system is jammed, serious consequences will be caused. Technical indicators: 1. External power supply: 24V DC 2.
