Product Description

 

Product Description

 

Intelligent Digital Pressure Switch with Dual PNP/NPN Output, 4-20mA Analog, IP65/IP67, High Accuracy LCD Display

 

1. Product Introduction 

Elevate your process monitoring with our Next-Generation Intelligent Digital Pressure Switch. This all-in-one device combines a precise pressure sensor, a clear digital display, and programmable switch outputs in a compact, industrial-grade housing.

Core Features:

• Dual Switching & Analog Output: Equipped with two independent PNP/NPN switch outputs and an optional 4-20mA/0-10V analog signal for seamless integration with PLC/SCADA.

• Rotatable High-Definition Display: Features a bright LED/LCD display that can be rotated for optimal visibility, showing real-time pressure in BAR, PSI, or MPa.

• User-Friendly Programming: 3-button interface allows for easy adjustment of setpoints, reset points, switching logic (Hysteresis/Window mode), and delay times.

• Superior Stability: Built-in digital compensation and filtering technology ensure high accuracy and long-term stability even under rapid pressure cycles.

 

2. Typical Applications 

• Machine Tools & CNC: Precise clamping pressure monitoring and lubrication system control.

• Hydraulic & Pneumatic Equipment: Real-time feedback for hydraulic power units and automated air pressure systems.

• Pump & Compressor Protection: High-precision dry-run protection and automated pressure maintenance.

• Water Treatment: Filter clogging detection and pipeline pressure regulation.

• Factory Automation: Ideal for assembly lines requiring high-frequency switching and status visualization.
