The M-SYSTEM 48NV-1YV6-R is a high-performance dual bargraph indicator from the renowned 48N Series, designed for demanding industrial environments. This panel meter provides clear, at-a-glance visualization of two separate process variables using advanced 101-segment LED arrays. Engineered for precision, this unit is pre-calibrated at the factory for a specific input range of 0 to 1000 mmH₂O (21416 MMH20 reference) and operates on a standard 24V DC power supply.
This model is ideal for applications requiring simultaneous monitoring of differential pressure, flow rates, or level measurements where visual trend analysis is critical.
Key Features & Benefits
- Dual 101-Segment LED Bargraphs: Offers exceptional resolution and visibility for tracking two variables simultaneously, allowing for immediate visual comparison and trend recognition .
- Factory Calibrated for 0–1000 mmH₂O: Pre-configured for specific differential pressure applications, saving setup time and ensuring accuracy straight out of the box .
- 24V DC Powered: Standard low-voltage DC operation (24V ±15%) makes it compatible with most PLC systems and industrial control panels, consuming approximately 2W .
- High Visual Accuracy: Delivers reliable performance with ±1% accuracy and a fast response time of ≤ 0.5 seconds, ensuring real-time process reflection .
- Rugged IP65 Front Panel Protection: Rated for dust-tight and water-jet protection, ensuring durability in harsh industrial environments (when properly mounted) .
- User Calibration Capability: While factory-set, the unit features on-board calibration buttons for Zero (Green LED) and Span (Red LED) adjustments to match receiving instruments or perform routine maintenance .
- Versatile Mounting: Supports both vertical and horizontal panel mounting configurations to fit various control desk layouts .
