The DPS Series is a range of compact, high-precision digital pressure sensors designed for real-time monitoring of compressed air and non-corrosive gases. With a dual-color digital display and programmable output logic, the DPS series provides the critical feedback needed for automated pneumatic systems and quality control.
Integrated perfectly with AR/BR Series regulators, these sensors replace traditional analog gauges with high-accuracy digital readouts and electronic switching.

Key Features & Advantages
1. Multi-Color Dual Display
The main display can be programmed to change color (Red to Green or vice versa) when a setpoint is reached. This allows operators to identify system status (OK vs. Error) at a glance from across the factory floor.
2. Versatile Unit Conversion
The DPS series supports multiple pressure units, which can be toggled via the front-panel buttons:
- MPa, kPa, kgf/cm², bar, psi, inHg.
3. Integrated Logic Functions
Built-in software allows for complex monitoring without an external PLC:
- Hysteresis Mode: Stable switching for fluctuating pressures.
- Window Comparator Mode: Keeps pressure within a specific “Safe Zone.”
- Auto-Preset: Simplifies setup by learning the system’s operating pressure.
4. Compact & Durable Build
The 30mm x 30mm square body is designed for space-saving panel mounting or direct attachment to regulator ports via an R1/8″ or NPT1/8″ fitting.
Installation & Wiring
Wiring Diagram (Typical NPN)
- Brown: +V (12-24V DC)
- Blue: 0V / GND
- Black: Output 1 (Switch)
- White: Output 2 (Switch or Analog 1-5V)
Port Connections
The DPS series typically features a standard R1/8″ (PT1/8″) thread with an included M5 internal thread, allowing for flexible piping options in tight spaces.
Applications
- Leak Detection: Monitoring pressure drop in sealed chambers.
- Pick-and-Place: Confirming vacuum suction for robotic arms.
- Safety Interlocks: Preventing machine operation if air pressure is below the minimum threshold.
- Electronic Regulators: Providing feedback loops for proportional valves.
Why Choose Anruk DPS Sensors?
- High Stability: Advanced temperature compensation ensures minimal drift in varied industrial environments.
- Anti-Chatter: Adjustable response times (2.5ms to 5000ms) prevent false triggers caused by rapid pressure pulses.
- Easy Setup: “Copy Mode” allows settings to be transferred from a master sensor to multiple slave units, saving hours of configuration time.
