SM-HC MODULAR SCANNER SYSTEM (For use with DCM-1 and DCM-2)
The SM1-HC switches both reference and active signals at the same
The SM2-HC is capable of switching currents at up to 50 Amps, a perfect
partner for the DCM-2.
The SM-HC system can handle up to 256 channels, all controllable from
For use with DCM-1 and DCM-2 DCPD units.
Monitoring of multiple specimens using one DCPD unit.
Monitoring multiple areas of interest on one specimen.
The scanner system provides a modular way of monitoring multiple specimens or areas of interest and
is designed for use in conjunction with the DCM-1 or DCM-2 series of crack growth monitors
manufactured by Matelect or indeed as a standalone scanner system.
The SM-HC system is modular and can be specified (or expanded) to cover a total of 256 specimen
channels. Each module is based on a 4 channel switching unit. Two types of unit exist; the SM1-HC
is used for switching the DCPD X and Y signals, whilst the SM2-HC is used to switch the DC
excitation current. Both modules are under the control of a single Scan Controller unit, the SC1 or in
the case of the DCM-2 a SC1 scan controller module built into the unit.
