The PSA/PSB Series are compact, digital display pressure sensors designed for precise pressure measurement and control. Featuring a high-brightness red LED display with adjustable display intervals, these sensors offer flexible pressure unit conversion and various output modes including hysteresis, automatic sensitivity setting, independent 2-output, and window comparative output. They are equipped with chattering prevention for stable output and a one-touch connector for easy wiring and maintenance. The sensors also include reverse power polarity and overcurrent protection, along with zero-point adjustment and peak/bottom hold monitoring functions. Ideal for sensing non-corrosive gases in various industrial applications.
