ZWY-4I Series Gate Opening Measurement and Control Instrument.

1. Introduction: ZWY-4I measurement and control instrument series products have wide adaptability, widely used in hydropower stations, reservoirs, lifting and other industries, suitable for all kinds of gates (flat doors, arc doors, herringbone doors, door cranes, bridge cranes, etc.) and lifting industry lifting height measurement, convenient to connect with various automatic control systems. Equipped with JZB-K and SSI optoelectronic encoders.

The five-digit high-brightness LED display on the front panel of the instrument shows the height of the gate opening more intuitively. The four-digit touch setting button is convenient for users to use and adjust parameters on site. The output of the relay is a passive contact, and the normally open and normally closed point is available for the user to choose.

4-20mA signal passive (active) output, convenient and reliable, strong anti-interference performance. RS485 signal is a standard MODBUS protocol, which is suitable for various types of PLC for communication. For the correction of arc door parameters, the instrument adopts 30 correction parameters to easily solve, eliminating the trouble of on-site mapping and arc door angle calculation.

The instrument housing is made of metal aluminum alloy material, which has strong anti-interference performance. The sensor signal input part is photoelectically isolated to avoid CPU damage caused by lightning strikes or static electricity. 2. Technical indicators.

Actually, I don't know.

The selection of load cells is mainly based on the following three points:

1. The most important point, that is, installation and external dimensions. A load cell that can be accurately installed into the equipment is a suitable load cell;

2. The second point is the measuring range of the load cell, and choosing the appropriate measuring range will help improve the weighing accuracy and ensure the service life of the load cell;

3. The output signal of the load cell, select the correct output signal to facilitate the subsequent signal reception and processing.

Sensor manufacturers can make a number of comparisons, choose affordable products, it is recommended to go to some sensor industry comprehensive ** to find, to our platform can also be.

Hello, I am a high-precision sensor technician in Bengbu, Anhui Province. Weighing cell manufacturers choose to decide according to the customer's own requirements, from the accuracy of the sensor, brand effect to determine the manufacturer, the choice of imported sensors is of high quality, but it is too expensive; If you consider the cost performance of the sensor, some domestic sensor manufacturers are also good.

The use of foreign sensor models is slightly better than the domestic one, but the first aspect is several times more expensive, so it is not recommended that you use foreign imports, in the country, you can use the brand of Spartato, the performance is similar to that of foreign countries, as long as the cost is not as expensive as foreign countries, I hope to help you.

The GJ series load cells produced by Bengbu High Precision Sensor Company meet the requirements from simple weighing to complex weighing, and provide high-quality load cell services across the country, which can be described as high precision! Stable performance! Superior quality!

Worry-free after-sales. **You can see it with high-precision sensing in the collection shop.

In fact, when it comes to sensors, everyone thinks of more foreign companies, I have to admit that the industry is doing better now, it is indeed foreign companies, and the world's top ten sensor companies are basically concentrated in Europe, America and Japan. It can be said that Germany, the United States and Japan are divided into three parts of the world, and the United States Honeywell and MEAS; German Siemens, Sick Company; Japan's Omron, Keyence, Panasonic, etc. are all well-known sensor companies in the world.

In fact, China also has a .. of powerful photoelectric sensor brandsIt's not hard wide, it's not hard, it's not hard, it's not hard).

Shenzhen Dashen Sensing brings together R&D and technical elites from Omron Corporation of Japan, focusing on the R&D and production of photoelectric sensor products, and its main products include fork photoelectric sensors, square photoelectric sensors, optical fiber sensors, proximity sensors and other series. DASS Dashen Sensing is one of the few enterprises in China that has completely mastered the core technology of photoelectric sensors.

Determined to make China's own sensor products, we hope to achieve mutual benefit and common progress with sensor users and sensor consumers in the wave of China's intelligent manufacturing era, contribute to the vigorous development of the sensor industry, and make a contribution to the revitalization of the national industry.

DASS has been working hard!

I can't measure which one is the best, but I personally feel that the photoelectric sensor of the Shenwu sensing unit is OK, and the equipment of this factory uses the photoelectric sensor of Shenwu, which is very good.

Balluff, ifm, Bonner By industry, what industry are you?

Shenzhen Lipu sensor is very good, the quality is not faulty, the main boss is very good, has been cooperating, it is worth recommending.

There are many types of photoelectric sensors, and there are many manufacturers. In China, the most used photoelectric sensor is Shenzhen Xindaowei. Many instruments and equipment have gradually changed from imported sensors to sensors with Xindaowei.

Shenzhen Xinyatu produces photoelectric sensors, using Japanese Toray fiber cores, domestic assembly and production, and has a good reputation in the same industry
