JZNC-XPP02B远传指示好就地指示视野大抗力强结构简单，不易损坏可靠性好，能连续使用
工作原理由一个LVDT（中频差动变压器式位移传感器）和对其进行保护的防护罩组成。LVDT由一个探杆与机壳相连。当机壳膨胀时，探杆在LVDT内移动，引起LVDT信号发生变化。信号经过调节后输出到监测器或DCS、PLC系统上，用于显示和报警。

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。

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.

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.
