| DART™
Digital Analog Remote Transducer |
- Take
a look at our new Digital Analog Remote Transducer (DART™)
the new way to win by assuring weld quality in your GMAW
welding process. The DART transducer provides the necessary
isolation and signal conditioning for remote weld data acquisition
sub systems.
- The
DART transducer converts the arc voltage, arc current and
torch shielding gas pressure to an isolated 0-10 vdc output
and the wire feed speed to a TTL level of 100 pulse/inch
output.

“Keep
your welds on target with the DART” |
- The
sensor is compact and provides a single cable connection
for all sensors. The
sensor is simple to install at the wire drive motor inlet
using industry standard quick disconnect conduit fittings.
The sensor may also be remotely mounted using industry standard
conduit assemblies and optional mounting brackets.
- The
DART sensor provides sensor output active LED indicators,
which provides visible indication of sensor activity.
- The
DART sensor is powered by an external 24 vdc power source.
- The
sensor is connected to an analog data acquisition system
via a single 8-conductor cable assembly. This
allows easy installation of the sensor to any Robot or PLC
controller.
- The
DART can also be used with other CWT weld controllers and
weld monitoring products to provide total weld quality control
and monitoring systems.
- The
DART™ provides total isolation of all sensors from
the welding arc. Arc current is measured using a laser trimmed
hall-effect transducer. Arc voltage sensor provides a 1
KV isolation using capacitive isolation technology. The
wire speed transducer is a precision optical encoder housed
in a Delron body, for isolation and mechanical rigidity,
with a heavy duty sealed bearing cartridge for increased
durability. An integrated silicon differential pressure
sensor provides torch shielding gas back-pressure measurements.
