SET button, which can be used to set the sensitivity. The basic principle of the sensor is to sense the refractive index of different media through a fiber optic probe, so as to obtain a digital signal, display it on the screen, and send the switching value by comparing the magnitude of the displayed value and the set sensitivity value. Indicator, when the sensor has a signal output, the indicator light is on. "Set Sensitive Value" appears in green on the screen to show the sensitive value set at that time. When the value collected by the probe becomes that value, the sensor generates a signal. The Current Sensitivity Value appears red on the screen to show the value collected by the sensor at that time. The "Pick Button" and the left and right arrows can complete the selection of various functions, which is equivalent to the page turning button. Form Selection Button: This button can be used to set up different work forms.
It must not be installed in the following places: direct sunlight, high humidity, frost, corrosive gases, direct oscillation or impact; When the power cord, power cord and photoelectric switch use the same wiring pipe or wiring duct, in principle, due to induction or product damage, separate wiring or shielded wires should be used. Use a 0.3 mm line to control the temperature above 1000 mm and below m, and when the power is turned on, it can be detected at least 200 ms. When the load is separated from the fiber sensor power supply, be sure to connect the fiber sensor power supply first; When the power supply is blocked, the output pulse will be presented, so the power supply of the load or load line is first blocked; When using the plug-in, in order to avoid electric shock or short circuit, please attach a maintenance patch to the unused power supply terminal; When removing and installing the expander, be sure to block the power supply; When the fiber optic unit is fixed in the expander unit, do not stretch or contract; Ensure that the protective cover is covered during use; Do not wash with banana water, gasoline, acetone, or lamp oil.
Instructions for the use of fiber optic sensors and precautions for use? Fiber optic sensors can also be divided into types such as retroreflective and diffuse reflection. Fiber optic sensors are able to detect objects from a distance. Because of fiber loss and dispersion, long-distance fiber transmission systems must be equipped with a center amplifier at the appropriate location on the line to process and amplify attenuated and distorted optical pulse signals.

Precautions for the use of gas flow meters - Autonex
1. When the working conditions of the exterior are changed (such as changing the medium, changing the ambient temperature, etc.), the zero position of the exterior should be adjusted from the beginning. At the same time, the outer surface of the catheter must be leveled and calibrated with a spirit level. Failure to do so will increase the effect of the change in operating conditions on the zero drift. Rack ...
