Dwyer MS Series Magnesense Differential Pressure Transmitter
Product Introduction
The Dwyer MS Series Magnesense Differential Pressure Transmitter is
a versatile solution for precise monitoring of micro pressure,
differential pressure, vacuum, air velocity, and volume flow.
Leveraging advanced magnetic induction technology, it ensures
exceptional stability and reliability across diverse applications.
The transmitter features field-selectable metric/imperial units, an
optional LCD display, adjustable output signal damping, and square
root output capability for use with pitot tubes or flow sensors.
Ideal for HVAC, cleanrooms, and industrial systems, it combines
adaptability with long-term performance to meet critical
measurement needs.
Product Features
Flexible Measurement Capabilities:
Monitors differential pressure, vacuum, air velocity, and volume
flow.
Square root output for velocity/flow calculations when paired with
pitot tubes.
Field Customization:
Selectable metric/imperial units (Pa, in w.c., etc.) via onboard
settings.
Optional 4-digit LCD display for real-time readings.
Adjustable output signal damping (0.5–15 sec) for stable
measurements.
Precision & Stability:
±1% FS accuracy for key ranges (0.25"–25" w.c.), ±2% for others.
±1% FS/year long-term stability for reliable performance.
Dual Output Options:
4–20 mA (2-wire) and 0–5/10 VDC (3-wire) for system integration.
Loop resistance: 0–1250 Ω (current), min. 1 kΩ (voltage).
Robust Design:
NEMA 4X (IP66) enclosure for protection against dust and water.
Pressure limits: 1 psi operation, 10 psi burst; temperature range:
0–150°F (-18–66°C).
Easy Installation:
Wall mounting with vertical diaphragm orientation.
European-style terminal blocks for quick wiring (16–26 AWG).
3/16" (5 mm) ID tubing connections for pressure ports.
