Dwyer MS - 111 Micro Differential Pressure Transmitter
Product Introduction
The Dwyer MS - 111 Micro Differential Pressure Transmitter, part of the MS series, is a highly adaptable solution for precise pressure and wind speed monitoring. Engineered with magnetic sensing technology, it delivers exceptional long - term performance, catering to thousands of pressure and flow measurement needs across diverse applications. Its compact design integrates user - friendly field - adjustable features, making it a go - to choice for building management, HVAC systems, and industrial flow monitoring.
Product Features
Unit Flexibility: Field - selectable between English (e.g., inches of water column) and Metric (e.g., Pascals) units, suiting global operational requirements.
Display Customization: Field - upgradeable 4 - digit LCD display, enabling clear, on - site pressure and flow data visualization.
Signal Control: Adjustable output signal damping (with optional display), minimizing measurement fluctuations for stable, reliable readings.
Flow Compatibility: Capable of square root output selection, ideal for use with pitot tubes and similar flow sensors to accurately measure velocity.
High Precision: Delivers ±1% accuracy (for applicable ranges), ensuring dependable data for critical pressure and flow monitoring tasks.
Durable Performance: Boasts ±1% FS/year stability, withstanding temperature variations (0 to 150°F / - 18 to 66°C) and pressure limits (1 psi operation, 10 psi burst) for long - lasting, consistent operation.
Versatile Compatibility: Works with air, non - combustible, and compatible gases, fitting into multiple industrial and commercial ventilation, HVAC, and building pressure applications.
Easy Integration: Offers flexible electrical wiring (4 - 20 mA 2 - wire or 0 - 10 V 3 - wire) and mounting (diaphragm vertical), simplifying installation into existing systems.
