What kind of accuracy can be achieved with the displacement sensor in those measurements! 5

Preferred for high-precision displacement sensorsMetroMedron's "precision mechanical sensor" has developed a "precision mechanical sensor" that has no precedent in the world in the industrial sensor industry, where electrical sensors are the mainstream. It can perform high precision even in harsh environments with coolant and chip splashing, and has more than 50 domestic and foreign patents with a high degree of originality. In the machine tool industry, the tool setter, which is used to detect tool tip wear, has been used by more than 96 machine tool manufacturers in 17 countries around the world, and has an excellent market share in the world.

It contributes to improving the accuracy and reducing costs of various industrial machinery, such as automobiles, machine tools, semiconductors, robots, medical devices, and smartphone manufacturing. By not imitating the product development of other companies, it supports global production in obscurity.

This has a lot to do with the measurement method and device, there is no problem with the accuracy of small displacement reaching 1um, and large displacement such as GPS ranging, about 10m.

It is true that it can achieve high precision, the technology of this era is very good to get high precision, ZLDS100 can reach one thousandth of the range, and there can be higher, such as ZLDS113 with higher precision!

It depends on what you are monitoring, if it is a large building, bridge, embankment, tailings, you can use GPS combined with various sensors and then use software system integration to monitor the displacement in real time, with high accuracy.

It depends on how high the accuracy you need to be in order to better use the displacement sensor.

Starting from the purpose of sensor application, sensors can be divided into mechanical quantity sensors according to the nature of the measurement: displacement sensors, force sensors, speed sensors, acceleration sensors, etc.

1.Starting from the purpose of sensor application, sensors can be divided into mechanical sensors according to the nature of the measurement: mechanical sensors, such as displacement sensors, force sensors, speed sensors, acceleration sensors, etc.;

2.Starting from the purpose of sensor research, focusing on the characteristics of the transformation process in Danxiang, the sensor can be divided into the following according to the output: Parametric sensor Its output is passive electrical parameters such as resistance, inductance, capacitance, etc., and the corresponding resistive sensors, inductive sensors, capacitive sensors, etc.

The degree to which the sensor corresponds to the measured can be expressed in terms of its sensitivity.

Transducer sensor is a detection device that can feel the measured information and transform the felt information into electrical signals or other required forms of information output according to a certain law to meet the requirements of information transmission, processing, storage, display, recording and control.

The existence and development of sensors allow objects to have senses such as touch, taste and smell, so that objects become alive, and sensors are the extension of human facial features. The sensor has the characteristics of miniaturization, digitization, intelligence, multi-functionalization, systematization, networking, etc., and it is the primary link to realize automatic detection and automatic control.

The definition of the sensor in the national standard GB7665-87 is: "a device or device that can sense the specified measurement and convert it into a usable signal according to a certain law (mathematical function law), usually composed of a sensitive element and a conversion element".

The China Internet of Things School-Enterprise Alliance believes that the existence and development of sensors allow objects to have senses such as touch, taste and smell, so that objects slowly become alive. "Sensor" is defined in the New Wei dictionary as: "a device that receives power from one system and usually sends it to a second system in another form."

Summary. The characteristics of several commonly used displacement measurement sensors are briefly described.

1) Absolute resistance line displacement sensor: a new type of sensor that can provide absolutely unique dynamic and static information at any position of linear moving parts. Absolute or relative measurement of displacements and position control are possible.

It is used in printing machines, bending machines and other mechanical equipment with complex working conditions;

2) Flexible hinge grid displacement sensor: a combined sensor component that cleverly combines the grid displacement sensor and the mechanical structure of the flexible hinge. Now it has been widely used in digital display, calipers, dial gauges and other measuring instruments;

3) Digital measurement of grating displacement: a displacement measurement method with high measurement accuracy, characterized by high precision and high speed.

4) Magnetostatic grating displacement sensor: one of the applications of magnetic sensing technology in the field of displacement sensor, with absolute coding characteristics, especially suitable for harsh industrial environments.

Please identify more than 3 types of sensors that are commonly used to test linear displacement, and briefly explain their operating principles and characteristics.

Linear Displacement Sensor, Rope Displacement Sensor, LVDT Displacement Sensor, Ultrasonic Sensor, Magnetostrictive Displacement Sensor, Infrared Displacement Sensor, Laser Displacement Sensor.

Among them, the linear displacement sensor has the most advantages.

1. There are many kinds of displacement sensors, laser, magnetic ==

2. The encoder can also be used for displacement measurement, but it needs to be calculated in the program for conversion, there are two kinds of incremental and absolute value, the accuracy is higher, if the accuracy requirements are not high, use several proximity switches or travel switches

Capacitive Sensors, Differential Transformers, Ultrasonic Sensors, Proximity Current Sensors, Infrared Sensors.

Displacement sensors can be divided into linear displacement and angular displacement, related principles and application articles can be searched in the sensor home, there are many above, **There are also many displacement sensor products released by members above, you can take a look.

By detecting the mark above, or the notch to count, each detected will have a signal output, the number of holes that can be detected per minute divided by the number of holes on each axle, the speed per minute can be calculated, in this way, the response time of the photoelectric sensor is required to be short, fast, or the response frequency of the sensor is required to be high, and the accuracy of measurement can be guaranteed.

We have customers who have applied this and received good results.

This is the displacement sensor you want to use, the displacement sensor is high-precision speed measurement, Europe and the United States, when the highest high, Japan's low, domestic quality poor.

The speed measurement with photoelectric sensors is very accurate. I don't know if you bought your digital flod or made your own. If it is purchased as standard, the measurement sampling time on the speed meter is 1s, 10s, etc.

The sampling time is 1s, and the geared disc that you install on the shaft to block the light should have 60 holes.

The sampling time is 10s, and the chainring that you install on the shaft to block the light should have 6 holes. If you make your own instrument, it depends on the accuracy of your sampling time. There is only one perforation, or with a reflective photoelectric sensor, each pulse is rotated, and the accuracy is not high.

Brother, I'm also doing an experiment report for this test. You're from the eight-character class, right?

Resolution: The smallest displacement that the sensor can resolve over a measuring range. For example:

The resolution of the sensor is millimeters when the displacement of the measured body changes in millimeters, and when the displacement of the measured body changes less than millimeters, the sensor reading does not change. Frequency of response: How many pieces of data per second the sensor can measure.

If 1000 measurements can be measured per second, the response frequency is 1000HzIn fact, the main basis for choosing a sensor is what you want to measure, and in what environment you want to measure, for example, in a harsh environment, dusty or in a hot liquid, you need to use an eddy-current sensor. If you want to measure strong electromagnetic fields in the environment, a laser sensor is more appropriate.

The displacement sensor is a small range, generally within 2 meters, if you want to measure tens of meters or hundreds of meters, you need to use a laser rangefinder.
