1. Avoid scum deposited in the conduit and touch the sensor with corrosive or overheated media. 2. When measuring the gas pressure, the pressure valve should be opened at the top of the process pipeline, and the sensor should also be installed in the upper part of the process pipeline, so that the accumulated liquid can be easily injected into the process.

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.

In what ways does the signal fail to manifest Allah? Why is the signal unstable? Generally, the output signal is unstable due to transient temperature changes that cause the bias voltage to fluctuate and fluctuate. How to deal with it? A sensor with a stable bias voltage is used for processing. ...

When there is a problem with the sensor, do you know what went wrong and what is the cause of the problem? There are four main types of sensor problems, namely complete failure problems, fixed error problems, drift error problems, and accuracy degradation problems. ...

The first type: screw device The method device should be selected quenched steel screws, at the time of the device, the screws are first screwed into about half the length, the screws should be straight with the surface, the sensor should be fixed according to the specified torque, and a layer of grease should be applied to the joint surface.

Resistance strain gauge is a kind of element used to measure strain, which is made of 0.02-0.05mm diameter constantan wire or nickel-chromium wire wound into a grid (or corroded into a grid with a very thin metal foil) in two layers of insulating sheet (substrate), and is connected with tinned copper wire and strain gauge wire as a strain.

1. Materials Load cells require stringent parameters such as creep of the output signal, temperature drift and zero point stability, so the metal properties of the sensor elastomers such as deformation, internal stress relief, as well as zero point stability and temperature compensation on the strain gauge are more demanding. And the load cell ...

The condition for the replacement of the load cell is that the axis of the applied force coincides with the axis of the force of the sensor, and we should know one thing, that is, with the increase of the rated load, the microvolt/indexing signal output by the sensor decreases. About the second ...

Temperature and humidity are closely related to people's lives, which has led to the creation of a sensor that integrates temperature and humidity. A temperature and humidity sensor is a device or device that converts the amount of temperature and humidity into an electrical signal that can be easily measured and processed. When buying a temperature and humidity sensor, you need to pay attention to ...

1. The load cell in a high-temperature environment will cause problems such as melting of coating materials, solder joint openings and changes in the stress structure of elastomers. Load cells operating in high-temperature environments usually use high-temperature sensors; In addition, they must be insulated, water-cooled, or air-cooled, etc. ...

In this era of rapid development of testing skills, if you want to mention the front-end testing system, it is the sensor, which is the soul of the entire testing system. In recent years, the rapid development of information skills has provided a good environment for the development of sensors, making them gradually become digital, multi-functional and intelligent.

There are two ways to move a displacement sensor, but which two methods are there? We're going to talk about that today. Displacement is a quantity related to the movement of the position of an object in the process of motion, according to the different motion methods, the displacement sensor can be divided into linear displacement sensor and angular displacement transmission ...

Whether it is a linear displacement sensor or a rope displacement sensor, it often encounters a variety of problems when it is used, including quality problems, application problems, environmental problems, etc., but the use of problems is common, and improper use is easy to damage the sensor. So what we're using ...

In daily operations, we often encounter the use of temperature sensors, thermocouples and RTDs are used as temperature sensing components, but their principles and functions are different. What are the differences? ...

The static characteristics of a sensor refer to the correlation between the output and input of the sensor for the static input signal. Since neither the input nor the output is moment-independent, the relationship between them, i.e., the static properties of the sensor, can be used as an algebra without the moment variables.

Assuming that the power supply is normal, it is necessary to carry out simple pressurization to see if the output has changed, perhaps to observe whether the zero position of the sensor has output, assuming that it has not changed, the sensor has been damaged, and vice versa, it is the appearance of the damage or other links of the whole system. ...

Temperature sensors are widely used in various occupational fields, such as: medical occupations, heavy industry, water treatment, wind power occupations, rail transit, HVAC occupations, energy and environmental protection, food occupations, hydropower stations, petrochemical industry, metallurgical industry, printing and dyeing pharmaceutical and other occupations are used. ...

The application of hysteresis dynamometer in the field of dynamometer application (HD series) is suitable for the testing of low to medium power (up to 14kW intermittent mode) motors. The hysteresis dynamometer does not need to rely on the speed to generate torque, but uses the hysteresis braking system, which can carry out the whole process experiment from no-load to lock-up. Lag...

1. Types of light sensors 1. Ambient Light Sensor XJC-S05-T New Jingcheng Sensor 503 Series HubaControl Fuba WTAL121-N30LMWoosen WSPSS15B20GTWang Sensor Jude Life CS20D, e.g. sensor on mobile phone on laptop etc.

The first thing is to see whether the signal is enough to use, for example, if you want 20KG, the signal must be more than 1.0, and it must not be used if it is calibrated to 20kg as long as it is 0.05MV. Therefore, the meaning of sensor calibration is to see if the sensor is qualified. Calibration of sensors ...

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 ...
