Seek a differential pressure transmitter with corrosion resistance
Thread Content
I need to measure a differential pressure of around 100 Pa, and the medium is something like ammonia water; therefore, the sensor itself needs to be corrosion-resistant. Thank you.
Models such as EJA and the 3051 series all come equipped with micro-differential pressure transmitters, and they can handle a working pressure of 100 Pa without any problem； As for the corrosiveness of ammonia, it’s not a problem at all; 316L material is more than sufficient.
We can handle this; we can discuss it
Micro-differential pressure measurement can be achieved by many transmitters; regarding the issue of corrosion, it is sufficient to choose a corrosion-resistant material for the parts in contact with the liquid.
I’m not familiar with chemical engineering, so I can’t specify the exact components; it’s probably a mixture of ammonia gas and other gases. I use it to check whether the pipes are blocked by crystals, and the pressure difference is estimated to be around 100 Pa.
Are you in the instrumentation field? Do you mean that a pressure of 100 Pa cannot be measured? The measurement range of the EJA120A is from -1KPa to 1KPa, with a range ratio of 10:1. Does that mean, in your view, it’s not capable of measuring a differential pressure of 100Pa? For our company’s spray granulation export operations, the air pressure process condition is between -50Pa and 50Pa, and EJA’s pressure transducers are used for this purpose; their accuracy is quite high. Besides, you’re already an adult – stop making personal attacks so often; don’t bring shame to people with culture.
The original poster should take a look at the selection manual for the EJA120A; it contains detailed calculations regarding accuracy (accuracy and range are not in a purely linear relationship). The actual accuracy level required for testing is one tier lower, and I don’t think it’s feasible from a technical standpoint to focus on differences of 1 Pa or 2 Pa. I don’t know which manufacturer is responsible for the 5th floor; those who can’t do it themselves resort to attacking others. I have no desire to waste words with them.
If it were up to me, I would choose the EJAW118 series; it’s okay
I’m sorry, I thought it was 100 KPA
The EJA120A series is a bit dangerous, as its range is 100PA–1000PA
