XT610 XT610 differential pressure transmitter differential pressure transmitter is a measure of the difference between the ends of the transmitter pressure transmitter, output standard signal (eg 4 ~ 20mA, 0 ~ 5V). Differential pressure transmitter pressure transmitter with the general difference is that they have two pressure ports, the differential pressure transmitter is generally divided into positive and negative terminal end, under normal circumstances, a positive pressure differential pressure transmitter should be greater than the pressure side to the suction side pressure measurement.

II. Introduction to differential pressure transmitter is used to prevent pipe directly into the transmitter in the media between the transmitter sense of laminated sheet filled by capillary fluid connected. It is used to measure liquid, gas or steam level, flow and pressure, and then into 4 ~ 20mA DC signal output. Figure cover for domestic brands 3051 differential pressure transmitters. Differential pressure transmitter for monitoring and control of the following several ways: ● ● viscous media at high temperature and crystallization of media ● with solid particles or suspended solids precipitated highly corrosive or toxic media ● media can eliminate impulse pipe pollution of the environment surrounding the leak occurrence; when using the spacer fluid can be removed, because the measurement signal is unstable, requiring constant isolation liquid supplement tedious work. ● continuous accurate measurement of interface and density remote device to avoid cross-mixing of different media moment, so that the measurement results truly reflect the actual situation of the process of change. ● hygiene demanding applications such as food, beverage and pharmaceutical industrial production, not only requires the transmitter wetted parts meet the health standards, and should be easy to wash, to prevent cross-contamination of different media. Three. Results of the design principles of the measured differential pressure transmitter as the name suggests is the pressure difference, that △ P = ρg △ h. And because the tanks are often cylindrical, its cross-sectional area of ??a circle S is constant, then the gravity G = △ P · S = ρg △ h · S, S constant, G is proportional to the relationship between △ P. I.e., as long as the accurate detection of △ P value, and is inversely proportional to the height △ h, changes in temperature, although the oil volume expansion or reduction, the actual level is raised or lowered, the detected pressure is always maintained constant. If you need to display the actual level, temperature compensation can also be introduced into the medium to be addressed. Four.
