The production of a qualified pressure transmitter requires many, many steps, from raw material inspection to finished transmitter inspection. From the selection of raw materials to the working environment of the transmitter, every step is crucial. Believe in professional manufacturers, they can bring you more benefits. "Quality isn’t expensive – it’s priceless." 😀😀😀

The flanged interface pressure transmitter, equipped with the unbeatable protection of the 2088 housing, is frequently seen on pipelines. It utilizes a piezoresistive silicon pressure sensor for pressure signal acquisition and converts it into standard electrical signals via dedicated circuits. The main structure is typically made of 304/316L stainless steel, featuring full-welded construction and an IP65 protection rating, making it suitable for high-temperature and corrosive media environments. This device has a measurement range covering -100kPa to 10MPa, with an accuracy level of up to 0.2%. It supports multiple output methods, including 4-20mA and HART protocols, and is widely used in pressure, differential pressure, and liquid level measurement across industries such as petrochemicals, power and metallurgy, and municipal wastewater treatment.

Our boss said not to upload this photo to the internet because it is used to fill the core with oil and is the core of the entire sensor production. But I think this reflects that we specialize in making pressure sensors, not just purchasing them. Arrange the cores neatly and let the device stand still for 24 hours, then fill the sensor with silicone oil. Do you think it's amazing?

I really like this pressure transmitter. It maximizes our advantages and has an IP68 waterproof rating, so you don't have to worry about being submerged in water. The most impressive thing is its membrane, which is very hard and can be used to measure mud, slurry, cement, crude oil without any problems, so there is no need to worry about damage to the membrane. The same technology is used for sensors used in shield tunneling machines. Do you need customized sensors? Come and try us out. 😂😂😂

The boss said that there is not enough manpower in the factory now, so he asked me to process the laser labels of these pressure transmitters. 300 pcs of pressure transmitters, I need two days to work from morning to night. Boss, can't you hire one more person?😅

A standard pressure transmitter, equipped with a Hirschman interface, is neatly placed on a plate, waiting for subsequent data inspection and appearance testing. This pressure transmitter can meet conventional industrial needs, with complete specifications, high quality and low price. Please rest assured that we do not cut corners. "Budget-friendly like a thrift shop, precision-rich like a lab."🤣

The flush membrane pressure transmitter comes with 8 heat sinks and can reach a maximum working temperature of 240 degrees Celsius, suitable for high-temperature media. Flat membrane structure, anti clogging. Made of stainless steel material, it feels heavy when held in the hand, and the quality is very good. Do you have any bosses who need this type of transmitter? Welcome to call or email.

Our pressure transmitters are all produced one by one under the careful operation of our colleagues. Installing the circuit board, installing screws, adjusting solder wires, and adjusting the angle of the circuit board, seemingly simple operations, are all accumulated experience bit by bit. Ensure that every sensor is of high quality when it leaves the factory. "Every screw turned = 1 year of ‘why-did-we-do-it-that-way’ wisdom." 😂😂😂

机翻 · 通用领域
The pressure transdcuer is an important part of the pressure transmitter/sensor, and its stability directly determines the quality of a pressure transmitter/sensor, so every link in the test step of the transducer cannot be missed. The transducer in the picture, just finished the welding package of the silicon chip, waiting for the stability test. Professional things, let the professional do it. "Stability isn’t an accident – it’s a thousand checked boxes."😂
