研制成功了测量温度和振动的光纤系统。业已表明,利用在传感器中波长交换原理,就能实现只用一根光纤连接传感器与仪器的测量系统。测量精度与光纤系统的性能,诸如光纤长度、光纤直径和所用的光纤连接器几乎无关。但上述性能对简化安装和降低费用非常重要。采用半导体工艺可批量制造传感器元件。在0～200℃的温度范围内,测温仪样机的测量精度为0.5℃。已研制了分辨能力为0.05g、动态范围为70dB的测量振动的光纤加速度计。上述系统已在各种不同的工业环境中作了试验,其性能可适合许多工业应用场合。光纤系统的优点在于其抗扰性,具有对电流绝缘和固有的内在安全性。
Developed a fiber optic system that measures temperature and vibration. It has been shown that by using the wavelength switching principle in the sensor, it is possible to realize a measuring system in which only one optical fiber is used to connect the sensor and the instrument. The measurement accuracy is almost independent of the performance of the fiber optic system, such as fiber length, fiber diameter and fiber optic connectors used. However, the above performance is very important to simplify installation and reduce costs. Semiconductor technology can batch manufacture of sensor components. In the temperature range of 0 ~ 200 ℃, the thermometer prototype measurement accuracy of 0.5 ℃. A fiber optic accelerometer has been developed that measures vibration at a resolution of 0.05 g and a dynamic range of 70 dB. The above system has been tested in a variety of different industrial environments and its performance is suitable for many industrial applications. The advantages of fiber optic systems lie in their immunity to current insulation and inherent inherent safety.
