Problems with diaphragm pressure gauges
Thread Content
I ordered a batch of diaphragm pressure gauges on behalf of the customer. The customer requested models made of 316L material, so I chose the YPF-100A model; firstly, it is cheaper, and secondly, I noticed that in the selection guide, the diaphragm and connector materials for both YPF-100A and YPF-100B are the same； After the results were sent to the user, it was said that it wouldn’t work – it’s not corrosion-resistant (to acetic acid)! I would like to ask: Are the measurement parts of YPF100A and YPF100B (the parts that come into contact with the object being measured) the same? ? Can YPF100A be used to measure acetic acid?
There are many types of diaphragm materials; it depends on what you choose
Could you explain what the difference between 100A and 100B is? I checked the samples but couldn’t find these two models
The poster should take a look at the materials used for the equipment and pipes. F4 or tantalum can be used.
One should not rely solely on the model number; the current range of models is too confusing, with some manufacturers assigning their own model numbers. When placing an order, it is necessary to specify the medium used and ensure that the product meets the required operating conditions.
