PEOPLE CAN HEAR THE SOUND DUE TO THE OSCILLATION OF THE OBJECT, ITS FREQUENCY IS IN THE RANGE OF 20HZ-20KHZ, BEYOND 20KHZ IS CALLED ULTRASOUND, BELOW 20HZ IS CALLED INFRASOUND. THE COMMONLY USED ULTRASONIC FREQUENCY IS TENS OF KHZ-TENS OF MHZ. Ultrasonic is a type of mechanical vibration in an elastic medium ...

(1) The Ultimate Problem Solver: Solve the most challenging applications by reducing sensor inventory with reliable, durable sensors (2) Regardless of the reflectivity of the target surface, the solution is difficult distance-based applications, including black foam on black plastic, black rubber in front of metal, multi-packing, etc.

1. Flange fixed installation Flange mounting is to connect the pressure sensor to the flange and fix the flange to the measured object. The advantage of this installation method is that it is simple in structure, easy to install and disassemble, and suitable for occasions where frequent sensor replacement is required. But...

1. Strain gauge pressure sensor Strain gauge pressure sensors are sensors that measure pressure primarily by measuring the strain of an elastic element. Depending on the material, strain gauges are divided into metals and semiconductors. When the conductor and the semiconductor material are mechanically deformed, their resistance value will change.

1. Photoelectric head dust masking When the photoelectric sensor is operating, it is easy to accumulate dust or oil dirt on the receiving head, resulting in problems such as insensitive sensor response, false triggering or non-triggering, and even failure to operate normally. At this time, we need to clean the photoelectric head. Cleaning method: ...

Depending on the mode of exercise Linear Position Sensor: The function of a linear displacement sensor is to convert the linear mechanical displacement into an electrical signal. In order to achieve this effect, the variable resistance slide rail is usually fixed on the fixed part of the sensor, and the displacement of the slide on the slide rail is measured.

1. Determine the installation location. Like injection molding machines, hydraulic presses, etc., are generally installed on the front 2 sides, and some non-standard equipment should be determined according to the actual situation to determine the installation position, to achieve the role of protection, without hindering the normal work. 2. Punching. Determine the installation location ...

The linear line works on the same principle as a sliding rheostat and is used as a voltage divider, which represents the actual position of the measured position with a relative output voltage. There are the following requirements for the work of this device: 1. If the electronic ruler has been used for a long time ...

The photoelectric head of a photoelectric sensor is a precision device, and misalignment can seriously affect the measurement results. This usually happens when external forces interfere with it, such as when the sensor position is shifted due to excessive force during cable construction. At this point, the position of the photohead needs to be readjusted. How to adjust: ...

1. There are 4 wires for the wiring sensor, among them, the red or brown wire is connected to the positive power supply, and the black wire is connected to the negative power supply; The green or blue wire is the dark output line, and the white or yellow wire is the bright output line, the user can choose one of them according to his needs, and the other is not used, but it should be insulated. Lines are not allowed ...

(1) The sensing element in the distributed optical fiber sensing system is only optical fiber; (2) The one-dimensional distribution map to be measured in the whole optical fiber area can be obtained in one measurement, and the two-dimensional and three-dimensional distribution of the measured can be determined by erecting the optical fiber into a grating shape; (3) The empty ...

The 2018 China Automation Industry Annual Conference and the 13th China Automation Industry Century Tour (CAIAC2018) were held on April 12, 2018 at Tianma Hotel, Shaoxing, Zhejiang. CAIAC2018 aims to remember and look forward to China ...

1. Use the 4 fixing screw holes at the bottom to install directly or add protection or other mechanical use according to the needs of the site and machine installation space facilities. 2. When installing the stainless steel cable, it is necessary to pay attention to the horizontal angle, that is, to make the mechanism of the steel cable from the outlet to the moving part as much as possible, and slide horizontally during work.

1. The use of ultrasonic spacer sensor skills An ultrasonic sensor consists of three parts: an ultrasonic transducer, a processing unit, and an output stage. First, the processing unit excites the ultrasonic transducer with voltage, and after it is excited, it announces the ultrasonic wave in the form of pulses, and then the ultrasonic transducer is transferred to withstand ...

1. First, power off the sensor and remove it. 2. Use a clean cotton swab dipped in an appropriate amount of anhydrous alcohol and quietly scrub the reception window. Be careful not to use water or organic solvents to avoid damaging the sensor. 3. After scrubbing, use a clean cotton swab to accept ...

1. Application in industrial automatic detection and automatic control system Sensors play an extremely important role in industrial automation production. In the petroleum, chemical, electric power, steel, machinery and other processing industries, sensors are responsible for detecting various information.

Liquid level sensors A liquid level sensor is a common sensor that measures the position of a liquid level, and it is an output that converts the height of the level into an electrical signal. The liquid level sensor is a modular circuit, which has the advantages of acid resistance, moisture resistance, shock resistance, corrosion resistance, etc., and the circuit contains constant current feedback ...
