Rail flaw GCT-8C professional manufacturer, the company also produces a variety of other track equipment, stable performance, affordable, rail flaw GCT-8C welcome new and old customers call to discuss GCT-8C rail flaw is digital rail trolley ultrasonic flaw detector, perform TB / T2340-2000 "A multi-channel ultrasonic flaw detector display rail technical conditions." Adapted to detect domestic and imported 43kg / m ~ 75kg / m rail base material exists in a variety of defects. The instrument has a host, the ultrasound probe, the tank containing the coupling agent is installed on more than 3 parts inspection trolley. The instrument has the following characteristics: two kinds of detection methods rail base metal A type detection. B-type base metal rail detection. 9 detecting channels, wherein a channel 0 °; 37 ° two-channel (front 37 °, 37 °); 70 ° channel six (before 70 °, after 70 °, within the first 70 °, before the outer 70 °, after within 70 °, after the outer 70 °). Full automatic testing data recording function (job route, testing speed, time, alarm condition, sensitivity, etc.), can be recorded continuously for 60 days to save the testing data. Can also be manually (manual) to store testing data. Supporting PC player software. Testing operations recorded data can be analyzed by continuous playback and playback software. A wireless phone interface, GPS positioning can be achieved, can achieve data transmission and remote control via the Internet. 8.4-inch color display diffuse reflection, the screen size is large, you can display more than 2.2 m B image; high brightness, no hood, clear display images in the sun, each channel A-type and B-type image pulses separated by a different color, easy to observe. The instrument type A and type B pulse with the screen image, simultaneous display. There are A-type pulse display, B-mode image shows two regions, while working without disturbing each other. There are two parameters display area, display job and dynamic parameters. The instrument is equipped with 40 touch keys, the operation is very simple, the main function (sensitivity, alarm switch, track-type selection, export documents, mileage proofreading, etc.) one-button operation, you can save hours of operation. The instrument has automatic detection probe, testing job, if the probe fails, may issue a prompt warning within three meters, you can also monitor the ultrasonic probe is coupled with good rail and determine the sensitivity of the site inspection personnel properly set by the playback software. Environmental adaptability can be operated at a temperature of -30 ~ 50 ℃ environment. Rain the whole structure, waterproof. Concise form new instrument will control the keyboard and hood integrated, easy button operation, built-in lithium battery pack. The main technical parameters of the detection channels: nine channels. Refresh rate: 60Hz / s. Probe Frequency: oblique probe 2MHz. Repeat detection frequency: 400Hz (per channel). Detection range: 0 ~ 200mm ± 4mm (43kg / m and 50kg / m rail); 0 ~ 250mm ± 5mm (60kg / m and 75kg / m rail); Gain control range: 0 ~ 80dB. Detection sensitivity margin: Perform TB / T 2340-2000 Dynamic Range: ≥30dB (suppression small), 2 ~ 6dB (inhibit large). Level linearity error: ≤2% vertical linearity error: ≤5% gain control range: 0 ~ 80dB attenuator error: not more than every 20dB (less than) 1dB alarm threshold: more than 50% of the full echo amplitude (A ~ I channel reflection Alarm), the echo is less than 30% full echo amplitude (0 ° or 45 ° dual-channel transmissive alarm) Alarm Frequency: 70 ° channel: 250Hz (20 ° angle oblique), 750Hz (direct); 37 ° Channel: 500Hz; 0 ° Channel: 1000Hz. Misconduct probe alarm: 2000Hz, speed alarm 2000Hz. Storage File: full 60 days are automatically stored files can be saved manually store files 2000 (to be upgraded). A pulse moving image: ≥60 minutes (to be updated). Operating voltage: 18 ~ 26V. Rated power: ≤8W. The machine can work for 10 hours. Working temperature: -30 ℃ ~ 50 ℃. Coupling agent capacity: 20L. Weight: 25 kg (without coupling agent).
