Select suitable pressure transmitter
2011-12-3 9:45:21

,但是由于工作环境,介质,介质温度等等的原因,所以 At present, due to the development of society, many industries are gradually adopting electronic pressure gauges, which is what we usually call pressure transmitters , but due to the working environment, medium, medium temperature, etc., so

What we must consider when selecting a pressure transmitter,


1.First wet material


所测量的介质 What we have to consider is the medium measured by the pressure transmitter


Can effectively prevent the medium from contacting the wetted part of the pressure transmitter, thereby protecting the pressure transmitter, and prolonging the life of the pressure transmitter

2.Accuracy level

Every electronic flowmeter will have an accuracy error, but because the accuracy level marked by each country is different


3.Range range


The maximum measurement range of general sensors is 70% of the full scale of the sensor.


4.Output signal

At present, due to various acquisition needs, there are many output signals of pressure transmitters on the market.

5.Medium temperature


的信号是通过电子线路部分转换的,所以一般情况下压力变送器的测量介质温度为-30到+100度如果温度过高,我们一般采用的冷凝湾来冷 Since the signal of the pressure transmitter is partially converted by the electronic circuit, the temperature of the measuring medium of the pressure transmitter is generally -30 to +100 degrees. If the temperature is too high, we usually use the condensation bay to cool it.

Cooling medium


6.Measurement medium


Generally, we measure relatively clean fluids, and we can directly use standard pressure transmitters.


7, other


的过程连接接口以及压力变送器的供电电压,如果在特殊的场合下使用还要考虑防暴以及防护等级 After confirming the above 5 parameters, we must also confirm the process connection interface of your pressure transmitter and the power supply voltage of the pressure transmitter. If it is used in special occasions, it is necessary to consider the anti-riot and protection level
