HSD type conventional ultrasonic testing instrument adopts modular platform design. The instrument platform follows the standard of 4U frame type industrial server shell, which consists of 1 power modules and N detection modules(1≤N≤8). Each inspection module has 4 independent ultrasonic detection channels, the 1 instrument platforms are equipped with 32 channels at most, and the instrument platform can be connected by synchronous cable, which can be extended to 400 channels.
Range of application
Suitable for ultrasonic testing of all kinds of plates, bars, tubes, billets and composites etc.
– The instrument parameters can meet the European Union standard (EN12668-1), and the factory inspection will be carried out by this standard, and the European certificate of inspection can also be provided.
– The repetition rate can reach 5KHZ, and the detection speed is up to 60m/min.
– The instrument channels are strictly independent and each channel has its own independent timing control of emission and reception.
– The instrument can expand the number of channels conveniently according to the actual needs of users, such as satisfying higher detection standards or increasing detection efficiency when testing.
– Instrument adopts the network transmission, fully meet the TCP/IP protocol, using optical fiber transmission can realize the long distance separating arrangement of instruments and computer (distance can be up to several hundred meters or even kilometers grade), and can reduce the interference, but also to a large extent reduce the probe cable, provides convenience for better equipment maintenance.
– The instrument uses hardware peak hold function for flaw detection data.
– The instrument uses FPGA to process the echo data by correlation algorithm, which has two functions, one is to reduce false positives, and two is to reduce interference.
– The instrument can be input directly to the 4 axis encoder, with 12 inputs and 10 outputs.
