Metro M1/M3 Air Gage Display Column

In order to offer the best Compactness, Metro designs special devices according to the probes your using. You can contact Metro to help you to pick the most suitable device according to your needs.  The M1 or M3 units can work with your air gages to provide 1 (M1) or 2 (M3) measurement characteristics.

It is possible to connect probes from different sources or brand thanks to the M-Bus modules

Part Numbers:

13040:  M3 with 2 inputs for air gages

11040: M1 with 1 input for an air gage

ACS-PNE-003:  Precision air preparation unit

18193:  Cable with digimatic output for Mux and Mitutoyo DP1 Printer

Modules:

M3 AG:  The M3 AG has to be used with a high precision pressure set up. Metro can deliver this set up when providing the M3. It is recommended to do so to ensure the best use of the air gauging

MB-IO:  This M-Bus module is fitted with 8 input/outputs isolated with optocouplers allowing to get additional functionalities, for example, output for Go/noGo, input for preset or start dynamic measurement... The M-Bus modules are mounted on an aluminum profile allowing to mount them on a standard DIN rail. More information on this page: M-BUS

As an option, it is possible to connect up to 4 M-Bus I/O module fitted with 8 optocoupled inputs/outputs. (= max 32 I/O).  A screen allows the user to assign a function to a pin of the module very easily. 8 virtual Buttons/lamps allow for easy testing of your wires.

Available functions:

  • Go/NoGo
  • Calibration/Preset
  • Start dynamic measurement
  • Measurement transfer
  • Zero
  • Stop

Multifunctional Footswitch (P/N 18020):  The footswitch can be configured in different ways: preset, measurement transmissions, start dynamic measurements, and more.

M-Bus Cable for M3 (P/N 81213-1.5):  This cable allows to connect the compatible M-Bus modules (MB-IO, MB-RL and MB-TP) on an M3 display unit (MB-IO, MB-RL and MB-TP)

RS232 to Digimatic communication cable (P/N 18193):  This cable allows for the M1/M3 display connection to a multiplexer Mux from Metro.

RS232 to USB communication cable (P/N 45173):  This cable allows for the M1/M3 display t to communicate with a computer.  This creates a virtual COM port on the computer and is its delivered with a drive in CD format.

Connections/Interface:

USB Connection

The M1/M3  is fitted with a mini-USB connector with 2 functions :

  1. Power supply through a wall-mounted transformer. This transformer supplies a regulated 5V/1A DC voltage.
  2. Measurement transmission. If you connect your M1/M3 to a PC, the PC will detect and install automatically the M1 as a standard USB keyboard with the standard drivers of your operating system (Windows, Mac OS, etc.). When you will send the measurement, the value will be written on your PC screen where your cursor is, in the same way as it would have been typed with a keyboard.

No need to install any specific driver or software.

 

RS 232 INTERFACE

The RS232 interface allows us to monitor and configure all the M1 or M3 functions through ASCII commands or MODBUS-RTU protocol.

The M1/M3 is compatible with several SPC software, like Q-DAS® /qs-STAT®

 

GRAPHICAL INTERFACE

Below are examples of the graphic interface used on the M1 or M3 units.
