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.
