About Dcvg Holiday Detector
Dcvg Holiday Detector
Caltech India offers DCVG Holiday Detector.
Models: EPT-4000
Application:
It is powerful and an accurate equipment for detecting and tracking the escaping currents of pipelines.
Sophisticated electronic Milli voltmeter with a 20000 Mega-Ohm input resistance. Analog DCVG Holiday detector is able to detect very low voltage gradients and provide an easy method of finding any coating defect in a pipeline by using analog panel meter. Not only DCVG Holiday Detector is able to show ON and OFF voltage gradient of the pipeline, but its also able to show the difference between ON and OFF in interruption mode.
Easy Fault Detection with Audible and Visual AlarmsDetect coating defects quickly with the DCVG Holiday Detectors built-in audible and visual alarm system. This feature enhances safety and accuracy, ensuring reliable identification of faults in pipe coatings during inspection. The alarm system operates instantly upon fault detection, minimizing inspection time and reducing chances of missed faults.
Flexible Voltage Selection and Robust BuildAdjust the test voltage seamlessly using the rotary switch, enabling tailored inspections for both coated and uncoated surfaces. The device is engineered with a shock-resistant ABS housing and splash-proof design, maintaining performance even in demanding field environments. Overvoltage and undervoltage warning indicators add another layer of operational safety.
Portability and Extended Field UseThe detectors lightweight design (approx. 3.5 kg) and rugged carrying case facilitate easy transportation across remote sites. Powered by a rechargeable 9V DC battery, it offers 810 hours of continuous operation with automatic shut-off for battery protection, allowing uninterrupted workflow during extensive coating assessments.
FAQs of Dcvg Holiday Detector:
Q: How does the DCVG Holiday Detector indicate detected faults during pipeline coating inspections?
A: The detector provides both audible and visual indications when a fault is detected. This dual system allows inspectors to easily identify the location of defects in pipeline coatings, improving detection accuracy and convenience in diverse environmental conditions.
Q: What is the process for adjusting test voltage on the DCVG Holiday Detector?
A: Test voltage can be adjusted continuously between 0 and 30 kV using the rotary switch on the device.
