M-Bus : Universal bus for gauging probes and measuring instruments

 

 

 

 

Continuously improved and developed since 1996, Metro' M-bus allows connecting numerous gauging probes and instruments from various brands and technologies to the Metro display units.

It allows the user to keep the probes he already own and give him extended functionalities and performances by using a display from Metro.

The M-Bus is mechanically and electrically compatible with the Solartron Orbit bus.

 

The M-bus is based on a RS485 link that gives the possibility to have important distances between the displays and the transducers without loss of signal.

The module's enclosures and electronic have been redesigned in 2012 to offer better performance to the users.

The M-Bus modules are today made from an anodised extruded aluminium profile that can be clipped on a standard DIN rail. It is very adapted to be used on a severe industrial environment.

 

Below is a list of available modules.
