-Pressure measurement in a 0.1KPaG medium containing 40% hydrochloric acid
Thread Content
May I ask, for pressure measurement in a medium of -0.1 KPaG containing 40% hydrochloric acid, can a diaphragm pressure transmitter (diaphragm made of 316SS+PTFE or titanium) be used? If possible, could you recommend a specific brand and model? What size inch should the diaphragm be? The main issue is that the pressure is too low, resulting in insufficient diaphragm deformation and thus an inability to make a measurement. If a regular pressure transmitter is used, would a differential pressure transmitter be necessary for such a low pressure? What material should be used for the pressure guide tube? Are there pressure transducers made of tantalum, along with the corresponding pipe valves and fittings? What’s the price? Thank you all!
The size of the diaphragm affects the measurement accuracy at low pressures; for such applications, a differential pressure transmitter with a DN50 PN16 fluorinated diaphragm is used
