DPS Series Digital Pressure Switch
High Precision Dual-color LCD Display Pressure Sensor
Product Features
- Dual Row LCD Display: Features a highly visible dual-row screen that simultaneously displays the current measured value (4-digit) and the target set value (3.5-digit).
- Dual Color Indication: The main display changes color (Red/Green selectable) when the set pressure is reached, allowing for instant visual confirmation of the system status from a distance.
- Multiple Pressure Units: Easily switch between various global pressure units (kPa, MPa, kgf/cm², bar, psi, mmHg, inHg) directly from the menu.
- High Precision & Fast Response: Delivers an exceptionally low measurement error (±2% F.S.) and ultra-fast, selectable output delay times starting from just 2ms.
- Dual Outputs: Built-in dual NPN or PNP transistor outputs for versatile control of automated pneumatic circuits.
- Robust Environment Tolerance: Excellent vibration (10-500Hz) and impact resistance (100m/s²), designed for harsh industrial environments.
