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.
