About Dwyer MS 711 Magnesense Differential Pressure Transmitter

Dwyer Instruments MS-711

Magnesense Differential Press. Trans., 5 VDC, 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

FAQs of Dwyer MS 711 Magnesense Differential Pressure Transmitter:

Q: How is the Dwyer MS 711 Magnesense transmitter typically installed?

A: The MS 711 can be mounted directly on a wall or integrated into a duct using the included mounting screws. Its compact design and 1/8 NPT female threads make adaptation to most HVAC or process control systems efficient and hassle-free.

Q: What is the process for zero and span adjustment of this transmitter?

A: Zero and span adjustment are performed via accessible push-buttons on the device, ensuring precise calibration without special tools. Detailed instructions are included in the supplied manual for user-friendly configuration.

Q: When should I consider using this pressure transmitter?

A: This transmitter is ideal when you require stable, accurate measurement of low differential pressures (0250 Pa) in air or compatible non-corrosive gas applicationscommonly found in HVAC, clean room monitoring, and industrial process control.

Q: Where is the best mounting location for optimal performance?

A: For best results, mount the transmitter on a vibration-free wall or directly onto the air duct. Ensure that the measurement media complies with the specified air and compatible gases to maintain accuracy and device longevity.

Q: What output signal does the MS 711 supply, and how does it benefit integration?

A: It provides a linear 420 mA (2-wire) output signal, simplifying integration with most standard PLCs, BMS, and industrial control systems, delivering both diagnostic reliability and ease of data acquisition.

Q: How is device status indicated during operation?

A: The MS 711 does not feature a built-in display but utilizes an LED indicator to show operational status, thereby allowing for ongoing visual confirmation of functionality without opening the enclosure.

Q: What are the main benefits of choosing the MS 711 Differential Pressure Transmitter?

A: The key advantages include robust build quality with an IP65 enclosure, high accuracy, low maintenance requirements, simple calibration, and wide compatibility with standard industrial automation and building management systems.
