08:38 Aug-08-2006 DCVG Information
i need to know that is there any relationship between PSP and DCVG signal strength, i.e. it is recommanded to conduct dcvg if the signal strength is above 300 mV. and on the other side PSP should not be more negetive than -1.2 V. i am getting only 25 mV signal strength even on -1 V PSP. i need to locate the problem.
UCI hardness tester NOVOTEST T-U2 is is used for non-destructive
hardness testing of:
alloys by scales of hardness: Rockwell (HRC), Brinell
(HB), Vickers (HV);
non-ferrous metals, alloys of iron etc., and using five additional
scales for calibration;
with tensile strength (Rm) scale determines the tensile strength
of carbon steel pearlitic products by automatic recalculation from
Brinell (HB) hardness scale.
For highly attenuating materials, the performance of the system is critical. The ultrasonic sensors,
the scanning area and the system settings should be flexibly adapted to the test task and the material.
These high expectations are met with the new and modular testing system SONOAIR. With the world’s first air-coupled phased-array UT inspection system SONOAIR we developed a technology that works with up to 4 transmitter and receiver channels with freely configurable square wave burst transmitters as wells as low noise receiving amplifiers.
