MS2-W103

Overview

The Dwyer Instruments MS2-W103-LCD is a Magnesense II differential pressure transmitter designed for straightforward operation. It continuously measures and displays differential pressure once installed and powered. The device utilizes stable piezo sensing technology to monitor pressure and air velocity. It features selectable ranges, including high range options such as 10.0, 15.0, 25.0, and 50.0 inches of water column (inH2O). The unit provides simultaneous transmission of a 2-wire 4-20 mA current output and a 3-wire 0-5 V or 0-10 V voltage output via a removable European-style connector.

Feature Summary

• Combines stable piezo sensing technology with selectable measurement ranges for accurate monitoring.
• Features an integral field-upgradeable display that allows for local viewing of measurements.
• Provides simultaneous universal current and voltage outputs via a removable connector.

Applications

• Monitoring differential pressure in HVAC systems
• Measuring air velocity in ductwork
• Filter status monitoring

Procurement Notes

Verify the specific suffix (e.g., -LCD) to confirm the inclusion of the integral display, as this affects functionality. Ensure the selected range matches the application requirements, as the MS2 series offers multiple high-range options. Confirm power supply compatibility, typically requiring 24VDC. Check for the presence of the removable European-style connector for wiring configuration.

Selection Notes

Select the MS2-W103-LCD when both remote signal transmission and local visual verification are required. The integral display eliminates the need for separate tools during initial setup. Choose based on the specific pressure range needed, such as 2500 Pa or higher inH2O values. Consider the mounting style, as this model is designed for wall mounting. Verify output type requirements for current versus voltage signals.
