DVL FAMILY

Compact and high accuracy voltage sensors for Industrial and Traction applications

DVL - Voltage Sensors

The DVL product family constitutes a compact voltage sensor range designed to ensure high accuracy in both industrial and traction applications. Engineered for the electronic measurement of voltages, including DC, AC, and pulsed voltages, these sensors feature galvanic separation between the primary and secondary circuits.

Tailored for small and medium voltage measurements ranging from 50 to 2000 VRMS, DVL voltage sensors boast a unique compact design, providing a 30% reduction in weight and power consumption. They deliver excellent overall accuracy and are fully compatible with previous generations of transducers, such as the LV100 product family, in terms of performance and footprint.

Operating with our patented insulation digital technology, the DVL components combine low consumption, very high accuracy, and minimal temperature drift.

DVL – Features and benefits

DVL voltage

Features

  • Bipolar and insulated measurement up to 3000 V
  • Current output
  • Input and output connections with M5 studs
  • Compatible with AV 100 family

The DVL-UI electronic components come with their own features:

  • Unipolar and insulated measurement of positive voltage up to 1500 V
  • 4-20 mA output

Just like the rest of the DVL family, they are designed with input and output connections with M5 studs. In addition, they are also compatible with LV 100 product family.

Main characteristics

  • A unique design to cover all measuring ranges
  • Low consumption and low losses
  • Compact design
  • Good behavior under common mode variations
  • Excellent accuracy (offset, sensitivity, linearity)
  • Good delay time
  • Low temperature variation
  • High immunity to external interferences. 

Typical applications

DVL sensors are frequently employed in both railway settings (including fixed installations and onboard trains) and industrial applications. It is customary to encounter DVL sensors in the following applications:

The DVL-UI components are specifically designed for particular application fields, demonstrating optimal performance in substations and trackside applications.

DVL voltage sensors - Standard compliance

The DVL family is compliant with many standards applicable in the industry and traction markets: 

  • EN50155:2007 for traction applications
  • European Directive EMC 2004 / 108 / EEC: CE Marking
  • Using UL94-VO recognized materials
  • EN 50121-3-2:2006: Railway EMC standard
  • EN 50124-1:2001: Insulation levels
  • EN 50178:1997: for industrial applications
  • NFF 16101/2: Fire and smoke classification
  • Developed according to IRIS standard
