DVM Series Voltage Sensors

LEM DVM series compact voltage sensors with low power consumption are designed for precise measurement in industrial and traction applications

Image of LEM DVM Series Voltage SensorsLEM DVM series compact voltage sensors are engineered for precise high and medium voltage measurements in industrial and traction applications. These sensors support the accurate electronic monitoring of DC, AC, and pulsed voltages while ensuring galvanic isolation between the primary and secondary circuits for enhanced safety and signal integrity. With a measurement range spanning from 600 VRMS to 4200 VRMS, DVM sensors offer a unique combination of compactness and high accuracy, making them ideal for space-constrained and performance-critical environments.

Built on patented insulation digital technology, DVM sensors stand out for their low power consumption, exceptional accuracy, and minimal temperature drift. The product line includes variants such as DVM, DVM-B, and DVM-UI, each tailored to meet specific application needs. Whether deployed in railway systems — including both onboard and fixed installations — or integrated into diverse industrial setups, the DVM series delivers dependable voltage monitoring that aligns with the demanding requirements of modern power and control systems.
