Measurement principle
The electronic differential pressure system eliminates the typical inconveniences that occur in mechanical capillary systems, as well as temperature effects in capillary systems. Operation and maintenance costs are optimized as no recalibration or reconfiguration of the system is required in the event of a component replacement.
ADVANTAGE
Electronic differential pressure system eliminates the traditional drawbacks of mechanical systems, resulting in higher process availability and reliability
The architecture and design of electronic differential pressure systems minimize safety risks
Costs are reduced due to shorter installation times, maintenance, downtime, and spare parts
Process connections: Thread, flanges and hygienic connections
Process temperature: -40 to + 125 °C (-40 to + 257 °F), optional 250 °C (482 °F)
Measuring range: 100mbar to + 40bar (1.5 to 600psi)
Accuracy: per sensor up to ± 0.05%, per system up to ± 0.07%
