How to correctly select a pressure transmitter is a lot of technicians and procurement staff headache, in fact, the following points will be clear, the problem will be solved. First of all, you need to clarify the pressure transmitter needs to measure the medium is what. We can be measured medium is roughly divided into four categories: conventional gases and liquids; mud, crude oil, wet soil and other particles, impact media; viscous media; medical environment, such as high health media environment. This will help us to determine the specific model of pressure transmitter, economic pressure transmitter, shock-resistant pressure transmitter, flat-film pressure transmitter, hygienic pressure transmitter are dealing with different media environment. After selecting a good specific model, it is necessary to determine the range of pressure transmitters. General pressure transmitter range than the maximum value of some of the larger. In the use of pressure transmitters, by the impact of the field environment, there are peaks and persistent irregular up and down fluctuations, (such as high-power equipment interference) this instantaneous peak can damage the pressure transmitter, shorten the life of the pressure transmitter, so in the selection of pressure transmitters, we must give full consideration to the range of pressure. Determine a good measurement medium and pressure range will have to make a choice on the accuracy of the pressure transmitter. Each electronic measuring instrument will have precision error, simply put, the higher the precision, the higher the price. We can choose according to the requirements of working conditions and budget, the general accuracy level of 0.1%FS, 0.25%FS, 0.5%FS, 1%FS. The smaller the value, the higher the precision. Output signal selection. Due to a variety of collection requirements, the market has a wide range of output signals of the pressure transmitter, the main ones of which are 4~20mA, 0~20mA, 0~10V, 0~5V, RS485 and so on. The current output is two-wire, the voltage output is three-wire, and the RS485 digital signal output is four-wire. Other factors. After determining the above parameters, but also to confirm the process of pressure transmitter connection interface and pressure transmitter supply voltage. If the use of special occasions to consider the explosion-proof and protection level. These are based on the specific conditions of use to choose, such as the scene of no requirements for explosion-proof, choose the conventional type of pressure transmitter is enough.
