Model analysis and comparison of negative pressure sensors

2018-01-08 15:08:13

different life because of contact with industry and the differences of cultural level, there are a lot of things we never contact and understand, believe a lot of people haven't heard negative pressure sensor, even listened to a lot of people haven't seen, don't know what it is, what, what are the unique magic.To satisfy the curiosity of people, this article is to introduce the negative pressure sensors under the mode of equipment parts, to unravel the mysteries of the negative pressure sensor, and see what is the role of, what's the difference between the different types, please take these problems, with small make up to study and discuss together.

cyt - 114 negative pressure sensor performance is reliable, price concessions.Using imported diffusion silicon chips, circuit adopts signal isolation amplifier, cutoff frequency interference design, strong anti-jamming capability, lightning protection options) over voltage protection, current limiting protection, impact resistant, anti-corrosion design, etc.CYT - 114 negative pressure transducer application performance stability is highly evaluated by the manufacturers and customers in

working principle of the negative pressure transmitter

pressure sensor is in single crystal silicon on the diffusion on a wheatstone bridge, voltage resistance effect is bridge wall resistance value changes, produces a differential voltage signal.This signal via special amplifier,

then through voltage current transform will range corresponding to the signal into standard 4 ~ 20 ma / 0 ~ 5 VDC / 0 ~ 10

through in this paper, two types of negative pressure sensor, I believe you know about negative pressure sensor has a certain understanding, although we come into contact with the opportunity of life is not much, but through the study we can improve in the accumulation of experience, has the growth of knowledge in, which is fun to learning, we learn so much knowledge can come in handy when sometime, but really to need before if you can rely on the accumulation of made itself to solve the problem, that is how a sense of accomplishment, not to face the problem when you use knowledge, you will find you a book to the exclamation that should not be too much.
