PS-710V Digital Velocity Caliper System Special Features • • • • • • Direct digital readout of thickness or ultrasonic velocity Lightweight, portable system Alarm lights and audible signal for fast sorting of parts - above, below or within preset limits Velocity related to degree of nodularity in ductile iron Handles parts ½” to 2” thick on typical as-cast iron Automatic gain control offers exceptional accuracy, reduces variations resulting from back reflection amplitude General This unique digital-readout system is designed around Centurion NDT’s versatile PS-710 Pulse Ultrasonic test instrument. The system can provide digital display of part thickness (mechanically of ultrasonically measured) or of ultrasonic velocity. Since there is a relationship between velocity and degree of nodularity in ductile iron castings, the system is primarily used for sorting of such castings where other variables such as chemistry and heat treat ar

Equipment The display consists of four 1/2-inch high digits. A switch permits the operator to select readout of mechanically measured thickness, ultrasonically measured thickness, or velocity. Two sets of four thumbwheels are used to set upper and lower limits. Two red alarm lights and a green “go” light provide instant go/no go and above /below indication. An audio alarm may also be used to indicate acceptable conditions, permitting the operator to work without looking at the instrument. Relay contacts may be used to operate external equipment such as spray markers or mechanical sorters. The...
