PSA18-NOP Edco USA Pneumatic Pressure Sensor

Edco PSA18-NOP Pneumatic Pressure Sensor – Normally-Open Air-Activated Pressure Control

 

The Edco USA PSA18-NOP is a normally-open pneumatic pressure sensor that provides a reliable, air-driven signal when a specific pressure threshold is reached. Once the desired set point is achieved, the sensor closes to block air flow, making it ideal for applications that require air shutoff upon reaching a defined pressure level.

 

This sensor features an integral 5/32" (4 mm) tube connector for both air supply and signal output ports, ensuring easy and secure pneumatic connections. Built with a rugged aluminum housing, stainless steel spring and fasteners, and a Kapton® type HN film diaphragm, the PSA18-NOP offers durability, chemical resistance, and long service life in industrial environments.

 

Key Features:

• Type: Normally-Open (closes when set pressure is reached)

• Output Type: Pneumatic (air signal only)

• Port 1: Air Supply

• Port 2: Output Signal

• Tubing Connection: 5/32" (4 mm) tube push-in fittings

• Durable Construction:

  • Aluminum housing

  • Stainless steel spring and fasteners

  • Kapton® HN diaphragm for chemical resistance and sensitivity

• Mounting-Friendly Design: Compact form factor for easy integration into pneumatic circuits

 

The PSA18-NOP is well-suited for automation, sensing, and control systems where clean, pneumatic-only logic is preferred or required—particularly in sensitive or hazardous environments without electrical components.
