Differential pressure transmitter In the process of purchasing, what factors should be considered first, what accessories need to be added, and what on-site needs to be customized, many procurement and technical personnel are troubled by these problems, today our technicians for you to summarize and sort out a set of differential pressure transmitter purchase guide, for procurement and technical personnel to answer questions. Step 1: Differential pressure transmitter range No matter what kind of differential pressure transmitter we choose in the end, the first thing to confirm is the differential pressure range and single-ended static pressure. Because of the difference in range, the type of differential pressure transmitter selected directly affects the difference. For example, a site where the single-ended static pressure is too large, it is necessary to choose a differential pressure transmitter type 3051. The range is 0-0.1kpa, and the upper limit of static pressure is ±10 kpa, and a conventional differential pressure transmitter can be selected. Step 2: The environment in which the differential pressure transmitter is located There are two environmental factors that affect the differential pressure transmitter, one is the ambient temperature and humidity, and the other is the on-site interference situation. Differential pressure transmitters have strict requirements for both temperature and humidity. For example, for differential pressure transmitters used in indoor environments, select the ambient temperature of the transmitter between -40~85°C and the ambient humidity between 0%~95%RH. When used outdoors or beyond the above range, and there is rain or dew splashing on site, consider using the more expensive 3051 differential pressure transmitter. Under the working conditions of large on-site interference, the differential pressure transmitter purchased is best with a column rotary head type, or consult the manufacturer for professional product customization. Only differential pressure transmitters that meet the anti-interference requirements can operate normally in the field. Step 3: Differential pressure transmitter to be measured medium The medium actually measured by the differential pressure transmitter must be compatible with the transmitter contact material. to avoid damage or corrosion of the transmitter components. The temperature of the measured medium of the differential pressure transmitter also needs to be considered, and if the temperature is too high, it is necessary to equip the differential pressure transmitter with cooling accessories or change the position of the measurement point of the differential pressure transmitter. Step 4: Explosion-proof of differential pressure transmitter Explosion-proof parameters are an important technical parameter of differential pressure transmitters, and explosion-proof differential pressure transmitters must be used for explosion-proof requirements on site. The types of explosion-proof are also different, with different requirements such as intrinsic safety explosion-proof, isolation explosion-proof, dust explosion-proof, etc. Step 5: Display function of differential pressure transmitter Due to the difference in specific use requirements, whether the display function of the differential pressure transmitter is required is also to be selected. Differential pressure transmitters with display monitor the measured differential pressure in real time, of course, the price with display will be higher than without display. The above are the basic technical parameters, and transmitter companies with R&D and production capacity can also customize products for special parameters. Only by combining the on-site working conditions and selecting the parameters of the differential pressure transmitter step by step, can you purchase the differential pressure transmitter that suits you.
