Renewable Energy for a Sustainable World.

YURA 601 MONOCRYSTALLINE SILICON DIFFERENTIAL PRESSURE SENSOR ASSEMBLY

The BDSJ-DP300 monocrystalline silicon differential pressure sensor component adopts a monocrystalline silicon sensor chip made of Germany’s advanced MEMS technology and the world’s original monocrystalline silicon double-beam suspension design, achieving world-leading overvoltage performance and ensuring signal excellent stability. The built-in intelligent signal processing module realizes the perfect combination of static pressure and temperature compensation, and can provide extremely high measurement accuracy and long-term stability under a wide range of static pressure and temperature.

1 Overview

BDSJ-DP300 can accurately measure differential pressure and convert it into a 4~20mA DC output signal. The sensor can be operated locally through three buttons, or remotely through a universal handheld terminal, configuration software, or mobile APP. It can display and configure the sensor without affecting the 4~20mA DC output signal.

2 Product Feature
