introduction：Photoelectric sensor feature： ①Long detection distance： If you keep it in the opposite shot10mAbove the detection distance, etc，Other detection methods can be implemented（magnetism、Ultrasonic wave） Indelible detection。 ②Fewer restrictions on detecting objects： Due to the detection of objects caused by the shading and reflection for the detection principle，So its not like proximity sensorsEtc. limit the detected object in-metal，It can be on glass.plastic.Timber.Almost all objects such as liquids are detected。 ③Short response time： Light itself is high speed，And the sensor circuit is made up of electronic parts，So it does not include mechanical working hours，The response time is very short。

introduction：A load cell is actually a device that converts a mass signal into a measurable electrical output。The use of sensors should first consider the actual working environment in which the sensor is located，This is the correct choice of load cellvital，It is related to whether the sensor can work properly and its safety and service life，And even the reliability and safety of the whole weighing apparatus。The basic concept and evaluation method of main technical index of load cell are discussed，There are qualitative differences between the old and the new countries。There are mainlyStype、Cantilever type、Spoke type、Plate-ring type、bellows、Bridge type、Cylinder-type and other styles。 Major advantage： resistance、Inductors and capacitors are three kinds of passive components in electronic technology，Capacitive sensors are sensors that convert the measured change into a change in capacitance，It is essentially a capacitor with variable parameters。

introduction：Weighing equipment after a long time of use may appear inaccurate weighing phenomenon，For checking the weight scale，It will certainly cause product misjudgment。Prior to...“Weighing scale、Sorting scale components and routine maintenance recommendations”In which we mentioned，Generally, we need to solve these problems by calibrating the weighing controller。But sometimes no amount of calibration can get the scale back to normal，At this time, we must check in detail from the weighing mechanism of the inspection scale，The core component of the weighing mechanism is the weighing sensor。 Method step： 1、Check whether the sensor is deformed，Crack condition，If these circumstances arise，Contact the manufacturer to replace the sensor。 2、On-load controller（Weighing instrument）Found the sensor connection，Measure the sensor connection circuit in normal condition，Excitation voltage（EXC+toEXC-among）is5-10V，Output voltage（SIG+toSIG-among）Close to when the equipment is unloaded0，Less than the sensor large output。（Sensor large o

introduction：Angular displacement sensor： The sensor uses a specially shaped rotor and a wire winding coil，Analog linear variable differential sensor（LVDT）Linear displacement of，High reliability and performance，The rotating motion of the rotor shaft produces a linear output signal，Move around the factory preset zero±60（In all120）The degree of。 The phase of this output signal indicates the direction of displacement away from zero。The non-contact electromagnetic coupling of the rotor gives the product unlimited resolution，That is, the absolute measurement accuracy can reach a few tenths of a degree。 An angular displacement sensor is a displacement sensorOne of the models，Non-contact patented design，Compared with other traditional angular displacement measuring instruments such as synchronous analyzer and potentiometer，Long-term reliability is effectively improved。Its design is unique，In no use such as slip rings、lamina、Contact cursor、Measurement accuracy can be guaranteed under the premise of easily worn moving par
