Fiber optic sensors have a wide range of applications, covering almost all important sectors of the national economy, defense, and people's daily lives, especially in harsh environments. For many years, they have solved technical problems in numerous industries, and market demand is huge. What are the instructions for using fiber optic sensors and precautions for their use?
1. Instructions for Use of Fiber Optic Sensors
The SET button is used to set the sensitivity. The sensor's basic principle is to sense the refractive index of different media through an optical fiber probe, thereby obtaining a digital signal, which is displayed on the screen. A switching value is sent by comparing the displayed value with the set sensitivity value. The indicator light illuminates when the sensor has a signal output. The screen displays "Set Sensitivity Value" in green to show the currently set sensitivity value. The sensor generates a signal when the value acquired by the probe changes to this value. The "Current Sensitivity Value" is displayed in red on the screen to show the current value acquired by the sensor. The "Select" button and left/right arrows allow selection of various functions, equivalent to page turning keys. The "Mode Selection" button is used to set different operating modes.
2. Instructions for Use of Fiber Optic Sensors
Do not install in the following locations: direct sunlight, high humidity, frost, corrosive gases, direct vibration or impact; when the power cord, power supply line, and photoelectric switch use the same conduit or wiring channel, in principle, due to induction or product damage, they should be wired separately or shielded wires should be used. Please use 0.3mm wire, with a length between 1000m and 1000m; after powering on, detection should be possible within 200ms. When the load is separated from the fiber optic sensor power supply, be sure to connect the fiber optic sensor power supply first; an output pulse will appear when the power is cut off, so first disconnect the power to the load or load line; when using plug-in modules, to prevent electric shock or short circuits, please attach protective patches to unused power connection terminals; when disassembling and installing the amplifier, be sure to disconnect the power; when the fiber optic unit is fixed in the amplifier unit, do not stretch or compress it; ensure the protective cover is covered during use; do not clean with banana oil, gasoline, acetone, or kerosene.
Instructions for using fiber optic sensors and precautions for use? Fiber optic sensors can be categorized into reflective and diffuse reflective types. Fiber optic sensors can detect objects at a distance. Due to fiber loss and dispersion, long-distance fiber optic transmission systems must be equipped with intermediate amplifiers at appropriate locations along the line to process and amplify attenuated and distorted optical pulse signals.
