Selection of Rule 1, the transmitter to measure what kind of pressure: first determine the system to confirm the maximum measured pressure, in general, need to select a transmission is greater than about 1.5 times the maximum pressure range device. This is mainly in many systems, especially in the pressure measurement and processing, with a peak and sustained irregular fluctuations, such instantaneous peak can damage the pressure sensor 3051, however, since doing so will decrease the accuracy. So the 3051 price, you can use a buffer to reduce the pressure spikes, but it will reduce the response speed of the sensor. Therefore, when choosing the transmitter, to fully consider the pressure range, accuracy, and its stability. 2. What kind of pressure medium: to consider is the selection of a 3051 pressure transmitter medium measured, viscous liquid, slurry will plug the pressure port, solvents or corrosive substances will not damage the change transmitter in direct contact with the dielectric material. Wetted parts of the pressure transmitter material generally used is 316 stainless steel, 316 stainless steel if the media is not corrosive, so basically all the pressure transmitters are suitable for measuring the pressure of the medium; if the media of 316 stainless steel have corrosive, it is necessary to use a chemical seal, it will not only serve to measure media pressure, also can effectively prevent the contact of the wetted parts of the media and pressure transmitter, thus helping protect the pressure transmitter, prolonged pressure .3 life transmitter, transmitter requires much accuracy: Accuracy decisions are: non-linearity, hysteresis effect, non-repeatability, temperature and zero offset calibration, the temperature, the higher the accuracy, the more the price high. Each of the electronic meter will have accuracy error specification 3051, but due to the subject of each country is not the same level of accuracy. The results of the measured differential pressure transmitter name suggests is the pressure difference, namely △ P = ρg △ h. And since the tank is often cylindrical, its cross-sectional area of ??a circle S is constant, then gravity G = △ P · S = ρg △ h · S, S constant, G and △ P proportional relationship. I.e., as long as the accurate detection value △ P, and is inversely proportional to the height △ h, changes in temperature, although the oil volume expansion or reduction, increase or decrease the actual level, the detected pressure is always maintained constant. If you need to display the actual level, temperature compensation can be introduced into the medium to be addressed. 3051 brochures, 3051, China-Technology provided by Jinan-Technology Limited.
