BP93420D-I Differential Pressure Transmitter IP65 Protection and Stainless Steel Structure for Industrial Applications Air Differential Pressure Sensor
BP93420DI Differential Pressure Transmitter
The BP93420DI differential pressure transmitter accurately measures differential pressure through a Wheatstone bridge sensor chip. When differential pressure acts on the corrugated diaphragms at both ends, the output signal maintains a precise linear relationship with the pressure differential. This industrial-grade sensor is specifically designed for dry air testing applications across various industries.

Key Features
- Stainless steel structural design for compact installation
- Rigorous temperature compensation and aging screening for reliable performance
- Flexible electrical interface options: plug-in or direct wiring
Industrial Applications
- Differential pressure measurement for gases and liquids in pipeline systems
- Industrial process monitoring in petroleum, chemical, metallurgy, power generation, and hydrology
- Pressure measurement for pipelines and furnace chambers
