About Dwyer MS 131 Magnesense Differential Pressure Transmitter

Dwyer Instruments MS-311
Magnesense Differential Press. Trans., 0-10 V, 1, 2, 5 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.

Reliable Pressure Monitoring

The MS 131 is engineered for precise and stable differential pressure measurement of dry air and non-corrosive gases. With 1% full scale accuracy at 25C and factory calibration options from 0.25 to 1 in w.c., its perfect for demanding industrial environments requiring consistent results.


Flexible Installation and Versatile Output

Delivered with a universal mounting bracket, screws, and a comprehensive manual, the transmitter supports vertical (standard) or any orientation installation. Electrical connections use a screw terminal block, compatible with both 2-wire (4-20 mA) and 3-wire (0-10 VDC) configurations for seamless integration into various control systems.


User-Friendly Operation and Design

Benefiting from a digital display and LED bar graph, users can easily read real-time values. Configuration is simple with push-button or digital controls for zero and span, housed in a rugged molded plastic enclosure. The IP65 rating ensures performance in harsh environments.
