Brief Introduction: Been Designed successfully by our company, the model X-PCD2000 pipeline crawler is a kind of instrument for detecting the quality of welding line in long-distance pipeline. This instrument comes up to advanced world standard. It adopts imported Siemens S7-200 PLC as control center with  strong anti-interference resistance, high integration, High Capacity memory and simple programming operation, making the pipeline crawler getting all-around protection. The instrument is set with various protective measures, and the faults are clearly displayed through the display screen. High precision tube voltage adjustment making the setting parameters not changed with the reduction of energy capacity of battery.

The traditional pipeline crawler can’t control its tube’s current, so the radiographic film quality is always decreased because of the reduction of the energy capacity of its battery during operating。 The design of having constant tube current control is the pipeline crawler’s prominent feature, making the product exert the maximum using efficiency.

Simple and safe operation is one of the features of the crawler. The crawler adopts currently popular magnetic location method which has the advantages of safety, sensitivity and reliability. This product’s technology has got national patent.

Features:

l         Automatically inspect the energy of battery. When the voltage of battery is not enough, the crawler will turn back in time;

l         Constant tube current control ensures the consistency of radiographic film’s image;

l         High precision of tube voltage adjustment also ensures the consistency of radiographic film’s image;

l         Having various real-time protective measures in case of meeting water, over-voltage, zero voltage, over-current, zero current, meeting barrier, antenna falling off, X-ray generator falling off, over temperature of the X-ray generator, parameters setting failure, demo setting failure and etc.

l         The optimum program design of taking full account of the crawler’s working avoids any damage to the crawler’s inner components.
