About Dwyer MS 351 Magnesense Differential Pressure Transmitter

Dwyer Instruments MS-351

Magnesense Differential Press. Trans., 0-10 V, range 25 in H2O

The Series MS Magnesense Differential Pressure Transmitter is an extremely versatile transmitter for monitoring pressure and air velocity. This compact package is loaded with features such as: field selectable English or metric ranges, field upgradeable LCD display, adjustable dampening of output signal (with optional display) and the ability to select a square root output for use with Pitot tubes and other similar flow sensors. Along with these features, the magnetic sensing technology provides exceptional long term performance and enables the Magnesense transmitter to be the solution for a myriad of pressure and flow applications. Field Upgradeable LCD. No need to order two separate transmitters. Simply stock a transmitter and display and you can satisfy any customer's requests. Simply remove cover and snap the LCD onto the board. Field Selectable Ranges in metric or English. Lowers stock and inventory requirements. You'll always have the right transmitter for every job. Digital Push Button Zero and Span. Reduces calibration time significantly over other transmitters that utilize potentiometers. Lowers maintenance time and costs. Adjustable Digital Dampening smooths out unstable pressure fluctuations common in air flow applications. Field Selectable Air Velocity Mode for fan and blower applications. Unit provides square root output that accurately tracks fpm or m/s flow rate. No need for a smart programmable indicator or PLC to convert pressure to air flow. Reduces components and installation time lowering overall costs.

Precise Differential Pressure Monitoring

Ideal for demanding industrial settings, the MS 351 measures differential pressure from -50 to +50 Pa (selectable up to 2500 Pa). Its electronic processing ensures high accuracy (1% of full scale), making it suitable for HVAC systems, clean rooms, and environmental control applications where consistent performance is paramount.

Industrial-Grade Durability

Encased in a robust matte-finish polycarbonate housing with a seal made from silicone, the MS 351 achieves an IP66 (NEMA 4X) rating. This protects it from dust and water ingress, allowing for reliable operation even in harsh environments, both indoors and outdoors.

Flexible Installation and Easy Calibration

The transmitter is designed for wall or duct mounting, supplied with all necessary mounting accessories. Zero and span adjustments are easily performed using digital push-buttons, simplifying maintenance and recalibration tasks, and reducing downtime during setup or routine checks.
