Product Description

Dwyer MS series micro differential pressure sensor Ms-111 differential pressure transmitter


Product Description

MS series differential pressure transmitter THE MS series differential pressure transmitter is a very versatile transmitter for monitoring pressure and wind speed. This compact instrument has the following features: field options in British or metric units, field adjustable high LCD display, adjustable output signal damping value, square root output when using pitot tubes and other similar flow sensors. In addition to these characteristics, magnetic sensing technology provides superior long-term performance and can solve tens of thousands of pressure and flow applications.


product application


  • Building pressure monitoring

Important notes for installation:


• Cables must be fitted through 1/2" NPT cable gland or ATEX/IECEx conduit (not supplied with instrument).
• Make sure after cabling to close tight cover and cable gland, in order to maintain IP66 rating.
• Open cover only after de-energizing instrument.

Attention: Check local safety rules and warnings on unit and manual for a correct use of the instrument in hazardous areas.
