The use of industrial field level meter, what is the measurement and control of industrial site

The first part of yeswuyong said is right, the material of the bypass tube is determined by the medium and not by the instrument, but I think the latter is not correct, the electromagnetic wave of the guided wave radar is propagated along the guided wave rod (cable), the radar wave will not diverge outward, the diameter of the bypass tube can be measured if it meets the requirements, whether it is a plastic or metal bypass tube can be used guided wave radar; The electromagnetic wave emission of non-contact radar (that is, the horn type) has a certain angle and is a divergent wave, while the dielectric constant of plastic material is generally very low, and the radar wave can easily pass through the plastic pipe wall to cause energy loss and even produce an wrong echo signal, so the non-contact radar must be installed in the metal bypass tube.

If the bypass pipe is made of engineering plastic, the medium is corrosive, and the cost budget is not high, then you can use the bypass pipe of engineering plastic (pvdf, pp, pvc).

Radar, if the bypass tube is metallic, then the guided wave radar must be used (contact) If the bypass tube is plastic, then it's up to you.

Despise the ad garbage in the problem.

Answer: When measuring the liquid level with a bypass tube, guided wave radar is generally used. It's contact.

The material is mostly stainless steel or carbon steel, which is determined by the medium and process.

It's quality control. Nothing serious. Just look, it's not too technical.

You mean that the train passes through a certain section of the track is caused by the vibration displacement of the rails, so it is required to design the architecture of the Kaiyou measurement system according to the characteristics of the site, as for which laser displacement sensor, as a peer I want to use the imported ZLDS100 laser displacement sensor is very good, we have used this sensor for more than 5 years, very stable, very durable, hehe, after all, it is an imported instrument, before we also did ZLDS100 rail displacement tester system to tease Sun Sentong, The ZLDS100 laser displacement sensor is used as the core measurement component to detect the displacement of the railway track surface. Years of experience have shown that the detection results are still relatively accurate, and the ZLDS100 laser displacement sensor can be customized according to special needs in addition to the standard product.

I think that multi-bus is to communicate well with PLC or industrial computer, because different PLCs may support different bus types, and after integrating a lot of bus protocols in the device, it can be easily interconnected with PLC.

Save cables and easy wiring.

Micro-displacement measurement is mainly to use high-precision sensors, which are also used in many industrial applications, such as the nano-platform NM-XY-15A are sensors that can be used for micro-displacement measurement.

In principle, it is possible, but it is a very tricky problem to build a test bench, if the test bench itself is not accurate, then there is no need to measure, and the micro-displacement measurement has high requirements for the stability of the measurement object and the test bench, so it is generally used in the precision industry, and the industry (refers to the industrialization we often say) is very little, but as people continue to apply high, precise and cutting-edge technology to ordinary industry, micro-displacement measurement will definitely show its skills and be widely used.

Yes, it is very suitable, and sensors such as the nm-XY-15A of the nano platform can be used for micro-displacement measurement.

For real-time measurement of aluminum coil thickness, it is recommended that you use a laser displacement sensor. ZLDS100 in aluminum coil thickness measurement engineering. The thickness change value of aluminum coil can be accurately measured, and the thickness value of aluminum coil material can be obtained through simple technology, so as to judge the stage and condition of production.

It can be used for non-contact measurement of displacement, three-dimensional dimensions, thickness, object deformation, and vibration.

Displacement sensors can be used in many ranges, such as in industry.

The software filtering algorithm for the RC low-pass filter is as follows:

yn=yn-1 + k（xn - xn-1）

After ad, then you're a software filter, a filter.

If you know the coordinates of the national GPS control point, you can directly set up the instrument on that point for static observation or RTK dynamic measurement.

1. First of all, you have the data of the national GPS points to see if it meets the needs of your site 2. Check the accuracy of the national GPS control points, find more than 2 control points, use GPS static mode, or RTK dynamic mode to collect point coordinates, and check whether the GPS accuracy is a symbol requirement through the residual situation of static adjustment or RTK parameter adjustment.

3. If it meets the requirements, find more than 2 GPS control points, use static acquisition method, calculate the coordinates into the survey area, and then measure. If the GPS point is close to the survey area, within a few kilometers, you can also choose a GPS point that can cover the survey area, use RTK for correction, and directly carry out the project.

The points calculated by static methods generally need to cover the scope of the survey area, and the coordinate accuracy of static calculation is better, and the dynamic accuracy is generally about 2 cm in the plane and about 3 cm in elevation.

The control points are used to adjust the deviation to see how much error there is and what is being measured now.
