M2B Millennium BASIC

NetSafety M2B Millennium BASIC Single Channel Gas Transmitter


The NetSafety M2B is a Single Channel universal Gas Transmitter designed for the most demanding industrial applications. It is used when there is a local full-featured Transmitter required, but a character display is not. The Millennium M2B includes bright LED indicators for Power/Alarm/Fault conditions with an optional local HART interface.

  NetSafety M2B Millennium BASIC Single Channel Transmitter

The NetSafety Millennium M2B automatically recognizes any connected pre-calibrated sensors, and maintains an uninterrupted digital signal. This provides fast response times, and over 600m sensor separation.

The non-intrusive commands in Class1 Div1 areas are accessed via the external magnet which is included, and bright light indicators. The optional intrinsically safe HART port adapter can be added for access to the built-in data logging and advanced diagnostics.
