SM

The SM1-HF is capable of switching signals running at up to
100kHz.
The SM2-HF is capable of switching currents running at up to
100Khz and 2Amps, a perfect partner for the CGM-5.
The SM system can handle up to 256 channels, all controllable
from PDsoft, 100 from the front panel.

To increase the versatility of the CGM-5R crack growth monitor, Matelect developed a compact,
modular signal multiplexing system designed to allow multi-point monitoring of specimens
undergoing crack growth measurements.
In its most basic form the system is capable of measuring up to 8 signal points sequentially and the
most sophisticated version a maximum of 256 points. A basic system comprises an SC-1 controller
and either an SM-1 and/or an SM-2 multiplexing unit as shown in the picture.
The SC-1 can control up to a maximum of 100 current and signal channels which enables the
system to be simply expanded by the addition of SM-1 or SM-2 units as required.

For use with CGM-5R units.
Monitoring of multiple specimens using one CGM-5R unit.
Monitoring multiple areas of interest on one specimen.
