Differential pressure transmitter for measurement and control in the following several cases: ● at a high temperature viscous media ● media ● easy to crystallize with the solid particles or suspended solids precipitating media ● highly corrosive or toxic media may eliminate impulse pipe pollution of the environment surrounding the leak phenomenon; 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 different media moment, so that the measurement results truly reflect the actual situation of the process of change. ● high hygiene demanding applications such as food, beverage and pharmaceutical industrial production in 3051 pressure transmitter, not only requires contacting the media transmitter sites meet the health standards, and should be easy to wash diffused silicon pressure transmitter, in order to prevent different media cross-contamination. Fault detection in the detection of the differential pressure transmitter failure should understand the working principle of differential pressure transmitter in order to make us more convenient and efficient to find out why. Differential pressure transmitter works: the direct effect of differential pressure impulse lines from both sides in the transmitter sensor with bilateral isolating diaphragm pressure transmitter, liquid conduction through the diaphragm seal to the measuring element within the measuring element The measured differential pressure signal into an electrical signal corresponding pressure transmitter is passed to the converter manufacturers, after amplification and other processing into standard electrical signal output. Differential pressure transmitter of several common, practical measurement: 1, combined with the throttle element, differential pressure before and after the use of throttling element produces liquid flow measurement. 2, the use of the liquid pressure difference generated its own gravity, measuring the height of the liquid. 3, the direct measurement of different pipes, tanks of liquid pressure difference. Transmitters in the measurement process, often there will be some failures, failure analysis and process timely determination of ongoing production is essential. According to the daily maintenance of our experience, we summed up some of the determination of analytical procedures and processes.
