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.
