Sensor of the invention test device operation principle is illustrated below.
The detection process of Devices to test transmitting end sensor is as follows：
Devices to test handles "on" position, then opens sensor detector, presses the active button handle 5 and switches prism
Sensor 1 is received to the benchmark, then presses W keys in control panel, the benchmark receives the energization work of sensor 1 and started,
Then micro-lens probe 10 is put in Devices to test, passes device to penetrating with the transmitting on machine, then see and look into sensor
Current value is whether there is in display in test device panel, if it has not, indicator lamp D3 meeting luminous alarms, and buzzer sound production prompt.
Illustrate the emission sensor damage in equipment.If there is current value in LCD, and in the range of pre-set a reference value, then
It is normal.If gone beyond the scope, illustrate that equipment transmitting terminal degree of aging is close and scrap.The mistake if machinery equipment reports an error, pass
Sense report is red, and direct detection transmitting terminal is that have light, and test view is alarmed immediately, you can analyzes transmitting terminal failure in machinery equipment also
It is the failure of machinery equipment receiving terminal.
Devices to test receives end sensor detection：
Sensor detector is opened, the active button handle 5 is pressed and switches prism to the reference emission sensor 2, so
After press T keys in control panel, the benchmark connects the energization work of emission sensor 2 and started, then the micro-lens pop one's head in
10 put in Devices to test, with the receiving terminal on machine to penetrating, transmitting terminal that shield is lived on machine, then adjust in control panel
" AD " "+" "-" is then done machine electric current and adjusted, whether the current value in read machine equipment to minimum standard glow current value
It is bigger than normal, if explanation bigger than normal, which receives sensor, an aging, luminous reference current value is then slowly adjusted, by repeatedly adjusting,
Can determine whether the degree of aging of machinery equipment receiving terminal, sensor whether can with or conclude damage.
Sensor detector adjusts：
Under the cooperation of machinery equipment, crawl sensor detector adjusts " AD " key of key, subsequently into adjustment modes, passes through
Crawl "+" "-" key, sight look into the numerical value that LCD is shown, obtain a reference value of optimum state so that the precision of sensor detector
It is maximum.
In summary, sensor of the invention test device, popped one's head in using the micro-lens being installed on optical fiber, for stretching
The different positions for entering Devices to test carry out daylighting and pass light, so as to the emission sensor in device under test and receive sensor
Tested, and can be switched by the switching device, test result is shown, improves the reliable operation of machine
Property, while the operating efficiency of contact staff is also improved, maintenance cost is saved for company, pursues high-quality, high quality；Production in addition
It is product modularization, easy to use, subtract reduced-maintenance number.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
