HS 811 TOFD Detector
811 TOFD detector is a special ultrasonic time-of-flight diffraction detection equipment upgraded on the basis of the original HS810.It has achieved more functional expansion on the basis of inheriting the stable,simple and practical characteristics of the HS810
- OEM Service
- Customization
- Model
- HS 811
Functional features
- The receiving /transmitting channel is extended from supporting 3 groups of TOFD probes to supporting 6 groups of TOFD probes to collect data at the same time,so that the maximum coverage thickness of one scan is increased to 400mm,and the combination of multiple scanning modes can also be achieved
- Adopting a brand new appearance design,the overall weight is less than 2Kg
- Adopting an industrial grade 7-inch color capacitive touch screen with a resolution of 800X480,it can achieve clear visibility in low brightness or strong light conditions
- Upgraded to a brand new USB3.0 interface,with stronger data transmission capability and fully compatible with various USB external devices
- Added HDMI high-definition video interface,more suitable for external monitoring or teaching use occasions
- The newly added high-speed dual-band wireless network module and 4G module can realize various methods of wireless data transmission and real-time monitoring,and can support mobile terminals such as PC,tablet,and mobile phone
- Compatible with various accessories of HS810
- The filter bandwidth is adjustable in multiple levels,and the maximum bandwidth is increased to 0.5~30M,perfectly matching the requirements of high-frequency flaw detection.
- Dynamic adjustment range increased to 120dB
- Instrument software:equipped with SAFT (Synthetic Aperture Focusing) function, differential function and lateral wave straightening function at the same time.
- Offline analysis software:It has the function of SAFT (Synthetic Aperture Focusing) processing,the function of same screen comparison display before and after image processing,and the function of directly converting TOFD images into BMP bitmaps
- Offline image analysis:recovery and playback of A-scan waveforms recorded during scanning;statistical analysis of defect size and contour thickness/amplitude data;record conversion to ASCll/MSWord/MS Excel format report
