AirTAC DPH Series: High-Precision Digital Pressure Sensor (Analog Output)
The AirTAC DPH Series is a high-performance electronic pressure sensor specifically designed for real-time pressure monitoring and process automation in pneumatic systems. Unlike standard pressure switches, the DPH Series features a dual-output system that combines a digital transistor switch with a continuous analog output (1~5V or 4~20mA).
This series is ideal for applications requiring data logging, PLC feedback, and precise pressure regulation. With its vibrant 2-color LCD display and multiple output modes—including Suction Check and Leakage detection—the DPH series provides a complete diagnostic interface for your air preparation unit.
Key Product Features
-
Dual Output Capability: Features both a digital switch output (NPN or PNP) and a high-accuracy analog output (voltage or current).
-
2-Color Digital Display: The high-contrast LCD changes color (Red/Green) based on the output status, providing immediate visual confirmation from a distance.
-
Specialized Functional Modes: Includes Basic mode, Hysteresis mode, Window Comparator mode, Suction Check, and Leakage Mode.
-
Wide Pressure Ranges: Available in two versions:
-
Low Pressure (-01): Optimized for -100 kPa to 100 kPa (-15 to 15 psi).
-
High Pressure (-10): Optimized for -100 kPa to 1,000 kPa (-15 to 150 psi).
-
-
Flexible Electrical Connectivity: Available in Grommet type (pre-wired) or Terminal type (plug-in) for easy field maintenance.
-
Precision Sealing & Mounting: Integrated PT1/8, NPT1/8, or G1/8 threads with M5 female internal threads for versatile piping.
