Dwyer MSX-W10-PA Differential Pressure Transmitter – High-Accuracy Solution for HVAC and Cleanroom Applications

The Dwyer MSX-W10-PA is a high-performance differential pressure transmitter from the next-generation MSX Magnesense® Series by Dwyer Instruments (USA). Designed for accurate measurement of air pressure differentials, this model is ideal for HVAC systems, cleanrooms, air handling units (AHUs), filter monitoring, and duct static pressure applications.

1. Introduction to the Dwyer MSX Series

The Dwyer MSX Series is well-known for its accuracy, compact design, long-term stability, and easy installation. The series offers multiple selectable pressure ranges, making it suitable for various applications—from low-pressure cleanrooms to industrial HVAC systems.

The MSX-W10-PA is a wall-mounted model with medium differential pressure ranges (up to approx. 125 Pa), designed specifically for static pressure monitoring, airflow measurement, and pressure control in ventilation systems.

2. Applications of the Dwyer MSX-W10-PA

The MSX-W10-PA can be widely used in:

Cleanrooms and containment areas – monitoring positive or negative differential pressure.
HVAC systems – static pressure measurement, filter monitoring, fan performance evaluation, AHU/FCU control.
Filter status monitoring – detecting clogged or overloaded air filters.
Airflow measurement – indirect airflow calculation using square root extraction.
Building Management Systems (BMS) & PLC integration via 4–20 mA, 0–10 V, or 0–5 V output signals.
