Select The Pressure Transmitter From Which Area
Jul 20, 2017

With the development of the economy, many industries gradually adopt electronic pressure gauge, commonly known as pressure transmitter, according to the working environment, media, temperature and other factors, in the selection of products must be considered in many aspects.
1, the grade of precision any electronic measurement meter will have the accuracy error, each country region standard precision grade is different, Beijing Star sensor Technology Co., Ltd. Precision level and European and American countries to the same standard
2, the output signal is now due to a variety of acquisition needs, the market most of the output signal there are many kinds, mainly $number, 0~20ma, 0~10v, 0-5v and so on, but more commonly used is $number and 0~10v two kinds,
3. The temperature of the medium considers the signal of the product to be converted through the electronic circuit, therefore, under normal circumstances, the product measurement medium temperature is negative 30-100 degrees, if the temperature is too high, we can use the condensation bend to cool the medium, Beijing star sensor manufacturers to develop high temperature-resistant products will be much lower cost.
4, the range of general sensor measurement of the largest range of sensor full range is the best, that is, now to measure the pressure of 70bar, we should choose the range of 100bar.
5, measured medium usually we measure is relatively clean fluid, then the direct use of the standard pressure transmitter can be, if you measured the medium is easy to crystallization or viscous, then we will use the external diaphragm or and chemical seals used together, will effectively prevent the media to plug the pressure measurement hole.
6, the material of the liquid is the measured medium, usually the contact material used is 316 stainless steel, if your medium to 316 stainless steel non-corrosive, then basically you can be used for measurement. If the contact medium to 316 stainless steel corrosive, then need to use chemical seals, not only can measure the pressure of the medium, more effective to prevent the media and product contact with the liquid part, so as to protect, extend the pressure transmitter Soumei
