4-20mA Output Differential Pressure Transmitter Differential Level Sensor IP65 for Industrial

4-20mA Output Differential Pressure Transmitter Differential Level Sensor IP65 for Industrial

BP93420DII Differential Pressure Transmitter

The HT pressure sensor 0-35KPa BP93420DII differential pressure sensor and water pressure transducer utilizes piezoresistive diffused silicon sensor technology for precise differential pressure measurement in industrial applications.

Product Overview

The BP93420DII differential pressure transmitter employs advanced piezoresistive diffused silicon sensor technology. When differential pressure acts on the corrugated diaphragms, the Wheatstone bridge output provides accurate linear measurement. Ideal for gas and liquid differential pressure applications in petroleum, chemical, power, and hydrology industries.

Key Features

• Stainless steel construction for compact design and easy installation
• Rigorous temperature compensation and aging screening for stable, reliable performance
• Flexible electrical interface options: plug-in or direct wiring configurations

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
