Dwyer MS-111-LCD Magnesense Differential Pressure Transmitter

Dwyer MS-111-LCD Magnesense Differential Pressure Transmitter

Product Introduction

The Dwyer MS-111-LCD Magnesense Differential Pressure Transmitter is a versatile, cost-effective solution for monitoring pressure and airflow in industrial applications. Featuring selectable ranges (1, 2, or 5 in w.c./250, 500, 1250 Pa) and a 4–20 mA output, it combines precision measurement with field-upgradable LCD display for real-time readings. Leveraging Magnesense magnetic induction technology, the transmitter offers long-term reliability, adjustable damping (0.5–15 sec), and optional square root output for pitot tube applications. Ideal for HVAC, clean rooms, and airflow monitoring, it ensures accurate performance across a temperature range of -18 to 66°C (0 to 150°F).
