SZGB-7光電轉(zhuǎn)速傳感器的輸出電平適應(yīng)性強(qiáng)，能夠與各種轉(zhuǎn)速數(shù)字顯示儀配套使用，并且可以直接與計算機(jī)接口電路相連。這使得它在工業(yè)自動化、機(jī)械制造、汽車檢測等多個領(lǐng)域都有廣泛的應(yīng)用，為設(shè)備的轉(zhuǎn)速監(jiān)測和控制提供了可靠的解決方案。

The SZGB-7 Photoelectric Tachometer Sensor is a high-performance single-head reflective photoelectric tachometer measurement device. It adopts a modulated light structure, which provides the advantages of long measurement distance and immunity to ambient light interference. The sensor is equipped with integrated modulated light emission and reception units, capable of converting the reflected light signals from the measured object into electrical pulse signals to achieve non-contact measurement of rotational and linear speeds.

The sensor has a wide measurement range of 1 to 30,000 revolutions per minute and a detection distance of 50 to 150 millimeters. The output signal amplitude is stable, with a high level of 5 ± 0.5 volts for "1" and below 0.5 volts for "0", and it operates on a DC power supply of 10 to 14 volts. For reflection conditions, a 10×10 mm² directional reflective paper is required. The working environment temperature ranges from 5℃ to 40℃, with a relative humidity of no more than 85%, and the overall dimensions are approximately 80×28×39 mm (including the mounting bracket).

The SZGB-7 Photoelectric Tachometer Sensor features strong output level adaptability and can be used in conjunction with various digital tachometer displays. It can also be directly connected to computer interface circuits. This makes it widely applicable in various fields such as industrial automation, machinery manufacturing, and automotive testing, providing a reliable solution for rotational speed monitoring and control of equipment.
