Can Rosemount pressure transducer pressure sensing elements come into direct contact with acidic or alkaline media for measurement?
Thread Content
The medium is sodium bisulfite; due to the limitations imposed by the flanges, it’s not possible to use diaphragm-type silicone oil-filled devices. It is planned to connect stainless steel pipes directly to transmit pressure to the gauge for measurement – is this an acceptable approach?
It’s possible; the voltage transformer itself also has diaphragms, so it won’t cause any issue
The temperature should be below 120, and there should be no corrosion or wear
If the temperature and corrosivity of the medium have no effect on the pressure-sensitive diaphragm, it can be connected.
It’s just not clear whether the diaphragm of the pressure transformer can come into direct contact with corrosive substances
It’s been almost 4 years now; I’m not sure if there’s a leak in your transmitter pressure tube
