ShotChek current pulse monitors are a family of instruments
which measure the large pulses of electric current used to
magnetize materials prior to magnetic inspection, a non-destructive
testing technique used to locate defects in ferromagnetic metals.
Inspection Research, Inc., has developed the ShotChek Model
III current pulse monitor to provide both peak current and
pulse duration measurement in a package suitable for permanent
mounting in a plant environment. Additionally, the Model III
can automatically compare each reading to upper and lower limits
set by the user via the front panel keypad. Electrically isolated
contact closures which indicate the result of the comparison
are provided for connection to alarms, controllers, or other
equipment. These new features make the Model III compatible
with automated inspection facilities.
ShotChek Model III enables inspectors to know that their customers'
specifications for minimum amperage and duration are being
met. Duration measurements conform to the half-amplitude definition
of pulse width now being utilized by Exxon, Shell, and others.
