Diffusion silicon pressure
transmitter range, accuracy, pressure, temperature range, medium to introduce the determination of 1, diffusion silicon pressure transmitter range from diffusion silicon pressure transmitter to security concerns, generally choose the stress value in the standard range of jobs - 60%
80% advisable, abnormal situation that may occur in the whole measurement system is caused by overload pressure shall not exceed the diffusion silicon pressure transmitter allows ZUI big overload.
Measuring the dynamic liquid pressure pipeline, water dripping effect, should also be considered appropriate raised large diffusion silicon pressure transducer loads, also can be to my company for technical consultation.
2, diffusion selective diffusion silicon pressure transmitter and pressure transmitter precision level step by a number of parameters, the higher grades, the more expensive.
Users can according to the working condition of testing requirements and a single parameter precision indicators, to use lower prices to achieve higher accuracy requirement.
Diffusion silicon pressure transmitter is given three precision index is adopting international ZUI small squares or end group translation method.
When choosing the sensor.
Precision grade sure should be allocated according to the measuring system to sensor ZUI big error option.
Sometimes should also be considered when the zero drift, zero and full temperature coefficient into additional error.
3, selection of diffusion silicon pressure transmitter users according to the nature of the measured pressure, should first determine the choice table pressure (
Relative to the local atmospheric pressure)
Pressure or negative pressure, differential pressure, * varieties.
If measuring liquid level, but also determine the liquid level is above the free atmospheric pressure or pressure seal container.
If measure the sealing pressure container level should choose the differential diffusion silicon pressure transmitter, diffusion silicon pressure transmitter to choose 4 diffusion silicon pressure transmitter using temperature range diffusion silicon pressure transducer linear temperature compensation has been before they go out.
Some of the series of the transmitter in the assembly of the circuit and then has carried on the comprehensive temperature compensation.
The compensation scope has been marked in single diffusion silicon pressure transmitter is introduced.
If users have special requirements, can negotiate with our company.
For the use of wide temperature range and requested the high accuracy of users, but also in secondary instrument used in data processing software to perform the temperature error correction.
More than compensate area used, the temperature coefficient index is likely to be overweight, but can still use.
Long-term spread in the temperature limit area work pressure transmitter will shorten the service life.
User operating conditions such as working in the index of low temperature or ultra high temperature for a long time.
Can negotiate with our company special 5, the choice of the differential diffusion silicon pressure transmitter general differential pressure diffusion silicon pressure transmitter is usually used in high voltage side pressure is higher than the low voltage side is the differential case, although the diffusion silicon can be also used in the negative differential pressure sensor, generally two basic symmetric pressure side, but the suction side is generally not the other calibration, if user two high pressure side of symmetry, told otherwise.
The low voltage side is likely to appear in the system overload range use, at this time should be negotiated with our company 6 natural frequency, frequency response characteristics of the diffusion silicon pressure transmitter high relative to other diffusion silicon pressure transmitter, in addition to more is the lead pressure cavity structure of the sensor structure parameters influence and influence the size of the sensor structure matrix of rigid body, the latter can not no longer, so the main or pressure cavity effect, users order can negotiate with our company.
7, pressure transmitter, and the matching of measured medium diffusion and pressure transmitter interface and electronic 売 body by a variety of different structure of the material production.
Compatibility with different media, in order to obtain ZUI optimal use effect, not because of the media does not match and make the diffusion silicon pressure transducer is damaged, the user should understand when selection order accurate name, concentration and temperature of the medium basic parameters.
