Compact, Digital Display Pressure Sensors - PSA/PSB Series

The PSA/PSB Series are compact, digital display pressure sensors designed for accurate and reliable pressure monitoring. Featuring a high-brightness red LED display, these sensors offer clear readings and versatile functionality. They are suitable for a wide range of applications involving air and non-corrosive gases, providing features like selectable response times for chattering prevention, easy one-touch connector types for maintenance, and built-in protection circuits for reverse power polarity and overcurrent. The series offers both PSA and PSB models with different connector and pressure port options, ensuring flexibility for various installation requirements.

Installation and Usage Notes

• Suitable for Air, Non-corrosive gas.
• Do not use with flammable gas as it is not an explosion-proof structure.
• Ensure wiring is done with power off.
• PSA Series: Two bracket types (sold separately) for flexible installation. Pressure port: Rc1/8 (standard), NPT1/8 (option).
• PSB Series: Pressure port is M5. Use general one-touch fitting.
• Tightening torque for fittings should not exceed specified limits to prevent mechanical issues.
• After power supply, it takes 3 seconds to operate.

Error Displays

• ER1: External pressure input during zero point adjustment.
• ER2: Overload applied on control output.
