Continuously improved and developed since 1996, Metro' M-bus allows to connect numerous gauging probes and instruments from various brands and technologies to the Metro display units.
It allows the user to keep probes already owned and give him extended functionalities and performances by using a Metro display.
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 lost of signal.

The module's enclosures and electronic have been redesigned in 2012 to offer the best performance to users.
The M-Bus modules are today made out of 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.
MB-RS : Master module to connect the M-Bus multiplexers to a computer or a PLC using RS232 or USB
MB-IP : Master module to connect the M-Bus multiplexers to a computer or a PLC using Ethernet or USB
MB-4i/8i : connection of inductive gauging probes
Module to connect 4 or 8 inductive probes. Several models are available allowing the user to connect different brands of inductive gauging probes to the Metro display units:
- Metro (M802, M804S etc)
- Tesa type (GT21 , GT31 etc)
- Mahr / Feinprüf (P2004M, 1300 etc)
- Marposs (F10, F25 etc)
- Peter Hirt (T101F etc)
- Solartron Metrology (AX/1/S etc)
