Selection Guide by Measuring Medium

Different process media require different diaphragm materials and installation configurations. Selection should be based on media characteristics, temperature, pressure, corrosiveness, viscosity, and crystallization risk.

Corrosive liquids: Hastelloy, tantalum diaphragm, or PTFE-coated isolation options may be considered according to the medium and concentration.

High-temperature media above 100°C: Cooling devices or capillary remote seals may be required to protect the transmitter from excessive process temperature.

Viscous or crystallizing media: Flush diaphragm or flange-type pressure transmitters are recommended where applicable to reduce the risk of impulse line blockage.

General gases and water: Standard stainless steel diaphragm configurations are generally suitable for conventional applications.
