Industrial Multimeter and Thermal Clamp by Conrad Electronic

Conrad Electronic is introducing new industrial measurement technology designed for predictive maintenance applications at the maintenance München trade show, taking place on October 14 and 15 at the Event Center Messe München (MOC). The testing devices address the diagnostic requirements of networked DC industrial grids to prevent unexpected production downtime.

Predictive Maintenance and Industrial Grid Diagnostics
The shift toward Industry 4.0 requires smart monitoring solutions to handle the increasing complexity of factory power distribution. Modern manufacturing facilities often utilize frequency converters and networked DC grids, which introduce new electrical stresses such as harmonic distortions and hidden thermal overloads. To minimize production downtime and make processes more efficient, service teams require intelligent sensor technology that can identify faults before physical component failure occurs. Ralf Heinrichs, Vice President Sales Germany at Conrad Electronic, notes that the expansion of the trade show to two halls demonstrates the high interest in innovative technologies to minimize downtime in production and make processes more efficient.

Voltcraft VC-925 PV Multimeter for High-Voltage DC Grids
To safely analyze these high-capacity industrial networks, the Conrad team is presenting the Voltcraft VC-925 PV at booth 4-824. This premium-class multimeter is engineered specifically for the maintenance of industrial plants operating on direct current. The device provides CAT III 1500 V and CAT IV 1000 V protection classes, enabling safe voltage measurements up to 2000 V DC and 1500 V AC. Harald Lehner, Category Manager for Voltcraft Measurement Technology at Conrad Electronic, explains that in networked DC industrial grids, there is no room for risks, and these extreme protection classes give service teams absolute safety during every measurement process.

Voltcraft VC-791 Thermal Current Clamp with THD Analysis
For comprehensive fault identification, the VC-791 All-In-One current clamp combines three diagnostic functions into a single hardware unit. The device supports high-voltage measurements up to 1500 V DC with certified CAT III 1500 V safety. Additionally, it integrates a thermal imaging camera to identify heat-related fault sources without physical contact. The device performs Total Harmonic Distortion (THD) analysis for neutral conductor monitoring, preventing unnoticed overheating, while a harmonics analysis function reveals how heavily frequency converters are stressing the plant grid. Lehner adds that from invisible hotspots to grid disturbances, with thermal imaging and THD analysis in one device, the VC-791 uncovers faults before production comes to a standstill.

Strategic Procurement for Unplanned Hardware Failures
Despite advanced sensor and measurement technology, not every machine failure can be prevented. When a production plant experiences a sudden breakdown, replacement parts are required immediately. Conrad Electronic supports these critical maintenance operations with a procurement portfolio of over 10 million product offerings. Heinrichs states that for those wanting to learn how the platform succeeds in optimally supplying companies with technology, avoiding delivery bottlenecks, and simplifying complex procurement processes, the answers are at the Conrad booth at the maintenance trade show.

Additional Context

Within the industrial measurement market, the Voltcraft VC-925 PV competes directly with devices like the Fluke 393 FC, which also targets the CAT III 1500 V rating required for modern solar installations and high-voltage DC industrial environments. While standard industrial multimeters typically cap at 1000 V DC, the push toward 1500 V and 2000 V DC measurement capabilities is a direct response to the higher operating voltages of contemporary renewable energy grids and DC-coupled factory automation. Similarly, the VC-791 thermal clamp enters a niche occupied by specialized diagnostic tools like the FLIR CM276. By integrating THD analysis and thermal imaging directly into a 1500 V DC-rated current clamp, the VC-791 allows technicians to correlate electrical harmonic stress with physical heat generation in a single inspection step, eliminating the need to carry separate thermal cameras and power quality analyzers on the factory floor.
