Composition and classification of sensors – Turck

Collision sensors are control signal inputs in airbag systems. Its function is that when a car collides, the collision sensor detects the intensity signal of the car collision, and inputs the signal into the airbag computer, and the airbag computer determines whether to detonate according to the signal of the collision sensor.

To include a device with a new software channel, Turck is expanding the Q300 series. In addition to the CODESYS-based read/write heads developed for PLC integration, system integrators can now also use Linux-based versions. ...

First of all, when using load cells, it is necessary to adjust the orientation of the sensors. Think of the sensor as a fragile product, cut the oscillation of the sensor, and try to handle it gently, because many sensors have elastomeric devices planned internally, and these elastomeric devices are critical to the stability of the sensor, ...

1. Observe whether the appearance of the sensor is deformed and cracked. If this happens, contact the sensor manufacturer to replace the sensor. 2. Find the sensor connection terminal of the weighing controller (weigher) and measure the sensor connection circuit. In general, the excitation voltages (EXC+ and EX...

1. According to the measurement target and measurement environment In order to carry out a detailed measurement work, it is necessary to first consider the principle of the sensor to choose, which needs to be analyzed and many elements can be confirmed. Because, even if the same physical quantity is measured, there are sensors with multiple principles to choose from.

The photoelectric effect can be divided into two categories: the external photoelectric effect and the internal photoelectric effect, and the internal photoelectric effect can be divided into the photoconductive effect and the photogenerated volt effect. It refers to the phenomenon that electrons in an object escape from the surface of the object under the illumination of light, resulting in photoelectron emission. Equipment made according to the external photoelectric effect ...

1. Mechanical damage The most common fault of servo response encoder is various mechanical damage, including hardware damage to the encoder's internal component structure (code disc, shaft, bearing, etc.) due to mechanical oscillation, collision, impact, wear and tear. 1) Oscillation Pass...

Modularity will win over the field of mechanical engineering, but it is fully in line with expectations and reasonable. Other occupations may have successfully transitioned from craft production to continuous production. In the case of continuous production, the power can be increased through large-scale production. The monotonous process will be automated, so that the employee ...

1. It is forbidden to wire in the state of power on, and strictly wire according to the color on the wiring diagram. 2. The interval between the switch sensing surface and the measured body should be within 80 of the additional action interval to switch the operation firmly. 3. Adjacent switches are generally not suitable for series and parallel use, such as ...

1) There is a difference between the two-wire system and the three-wire system of the proximity switch, and the three-wire system is divided into NPN type and PNP type, and their wiring is different 2) The wiring of the two-wire proximity switch is relatively simple, and the proximity switch can be connected to the power supply after being connected to the load in series. 3) Three-wire proximity switch ...

1. Bright. It directly affects the visual effect of the touch screen. Bright, in the contact screen profession, is just a general concept, many contact screens are multi-layer composite films, only a little clear to summarize its visual effect is not good, it should include at least four characteristics: transparency, ...

Turck's inclination sensors, which combine MEMS and gyroscope signals for mobile applications, are now also available with switching outputs. Turck's QR20 inclinometer generates signals through a combination of two measuring principles: gyroscope signals and MEMS accelerometers (MEMS). Pass...

On April 22, the first 2021 Chengdu International Industry Fair kicked off in the Western China International Expo City. As the first show in the western region after the epidemic, Turck showcased the future-oriented IIoT ecosystem solutions for digital production to the Sichuan and Chongqing audiences.

1) Pay attention to the structure and data of the object to be measured, and the general laser displacement sensor needs to measure the triangular optical path with intact requirements. If the measured object has deep grooves or messy appearance, it may cause the triangular light path to be occluded, so that it cannot be measured. There are also some light-absorbing materials, such as black rubber and other materials, most of the light intensity will be ...

1. Sensor scale: (1) In normal use (static test or quasi-static test, the frequency of use is not high), the scale of the sensor should be selected to consider the force value of the measurement, but also to consider the weight of the auxiliary thing (test fixture) and so on.

A differential pressure sensor is a sensor used to measure the difference between two pressures, and is generally used to measure the pressure difference between the front and rear ends of a certain equipment or component. Typical Applications: It is used to measure the exhaust particle trap (DP ...

In modern industrial production, especially in the process of automated production, it is necessary to use various sensors to monitor various parameters in the production process, so that the equipment is in normal or optimal condition, so that the product can reach the best quality. Therefore, it can be said that if there are many excellent sensors, modern ...

1. Accuracy 2. Environmental conditions – there are usually limits on temperature/humidity 3. Range – the measurement limit of the sensor 4. Calibration – Essential for most measuring equipment, as readings change over time ...

1. Thermocouple Thermocouples are the most commonly used temperature sensors for temperature measurement. Its main benefits are a wide temperature scale and adaptability to a wide range of atmospheric environments, and it is robust, inexpensive, does not require electricity, and is also the cheapest. A thermocouple consists of two different metal wires connected at one end (metal A and ...

Turck's linear displacement sensors have an additional measuring stroke of 100 to 4500 mm. It uses the magnetoelastic principle and non-touch measurement method, and provides a high accuracy of μm according to the 16-bit D/A conversion resolution. It can be changed according to the actual application needs through a very simple programming method.
