Quality control of casting parts / DRM-10A

The DRM-10A is suitable for both in-plant maintenance and field. Resistance measurements are calculated automatically. This equipment has become the number one choice for industries, products engineers and manufacturers. Recognized as the most accurate and easy to use on the market, the DRM-10A is shock resistant and suitable for many applications.

Applications

• Quality control of  smelting parts
• Control of  mechanical joints and of  joints welded at high voltage
• Control of  exothermic joints (Cadweld®)
• Control of  electrodes for  aluminum plants
• Inspection of  contacts, circuit breakers and  power fuses

Advantages of the DRM-10A

• Much lighter and handier than  other equipment  in its category
• Shock resistant, it is suitable for all types of applications: work site or laboratory
• Its back-lighting liquid crystal display (LCD) enables it to be used in dark areas
• Weak current injection for  applications that require small measurement contacts
• A variety of probes adapted to types of specific measurements such as the inspection of exothermal welds. (Cadweld®), are available as options

Operation

The DRM-10A uses a four-pin resistance measurement system which consists of injecting a current with two cables connected at each end of the joint to be tested. Then, the cables are installed which allow  reading the tension on each side of the part to be tested in order to measure the resistance. This eliminates any uncertainty linked to resistance of the contacts. The instrument is equipped with a microprocessor which  eliminates  gaps and parasite voltages. Thanks to its unique filtering system, the DRM-10A can be used in spite of the presence of intense magnetic fields.
