Clearly define the measurement medium and operating conditions
Corrosive medium: Use Hastelloy film or PTFE lining (such as hydrochloric acid, chlorine gas measurement).
High temperature medium (>100 ℃): Choose high temperature type (with heat sink or capillary isolation).
Viscous/easily crystallizable medium: Adopting a flat film or flushing ring design to prevent blockage.
Range selection
The normal operating pressure should be between 1/3 and 2/3 of the range to avoid long-term use at full range.
Pulsating pressure: Select a range 1.5 times higher than the actual maximum pressure and install a damping valve.
Output signal and protocol
Conventional: 4-20mA+HART (strong compatibility).
Smart factory: Profibus PA/FF (digital bus).
