Proven Reliable In ISI Inspection
The Centurion PS-710B Pulse Ultrasonic Test Unit provides versatile flaw detection capability for many inspection needs. Its state-of-the-art performance and high reliability under critical inspection conditions are dependable on by many nuclear ISI inspection teams. It's also widely used in NDE test labs, as well as throughout the aircraft, automotive and metalworking industries.

The standard PS-710B building block model provides fast, accurate measurements for many routine manual tests as well as basic systems and laboratory applications. Additional modules offer an economical way to increase capability, including a gate with attenuation correction, AGC and velocity measurement. Analog time and amplitude outputs are available which permit hard copy testing (chart recording) and drive remote displays up to 200 feet away from the main unit.

Accessory Modules
The AT-1003 is a gate module for the PS-710B which allows the user to perform gating functions in the contact mode or interface (immersion) mode. The threshold point for the alarm, a visual and audible type, can be set an any point on the screen and tripped by an increasing signal (positive) or a decreasing signal (negative). Positive or negative gating is switch selectable.


Amplitude Correction: Gain control adjustable to reduce greatest signal in selected area by as much as 25 dB, to within 2 dB of selected level.
Range: 1.0-4.5 to 18 microseconds after initial pulse.
Caliper Interface: Provides interface between DR-1002 thickness/velocity module and standard Centurion velocity caliper. Standard measurement range - 1/2" (1.25 cm) to 3 1/2" (9 cm).


Display: 4-digit L.E.D. (.6" (1.5 cm) characters)
Accuracy: a) Time or Thickness: +/-0.5% of full scale +/-2 counts
