本机是一种浮子式红外线光纤液位传感器，能随时显示液面的高度。本机的特点是：第一，由于伸到被测现场的只是两对光纤，不会有引发危险的任何电火花产生，光纤又能耐酸碱腐蚀，所以适用于易燃、易爆、酸碱度很大的恶劣环境，如各种油罐、酸碱反应塔液位高度的显示；第二，本机采用３８ＫＨｚ的交流发射光源，光纤送出的是固定的３８ＫＨｚ矩形脉冲，而不是平稳的直流光信号，接收端的工作频率也调在３８ＫＨｚ上，这样就提高了传感器的抗干扰能力；第三，采用不间断电源，不怕停电和意外断电。
This machine is a float infrared fiber optic level sensor that can display the level of liquid at any time. The machine is characterized by: First, due to reach the site of the test is only two pairs of fibers, there will be no danger of any spark, fiber and acid and alkali corrosion, it is suitable for flammable, explosive, pH is very Big harsh environment, such as the display of liquid level of acid tank and alkali tank for various kinds of oil tanks; secondly, this machine adopts 38KHz AC emitting light source, and the optical fiber sends out a fixed 38KHz rectangular pulse rather than a steady DC light signal , The receiving end of the operating frequency is also transferred in 38KHz, thus improving the anti-jamming capability of the sensor; Third, the use of uninterruptible power supply, not afraid of blackouts and accidental power failure.
