High-Voltage Safe Measurement Systems High-Voltage Safe Measurement Systems

High-Voltage Safe Measurement Systems

Safe - Precise - Flexible

For measurement on high-voltage components with certified safety – in test drives, field tests, and on test benches: CSM’s high-voltage measurement systems are specifically designed for the safe and accurate acquisition of temperatures and analog sensor signals in HV environments, especially in electric and hybrid vehicles.

Safe and efficient measurements in high-voltage environments

Measurement systems from CSM provide safety from HV damage in the entire measurement chain - from the sensor to data acquisition software, and the user. As with our other CAN and EtherCAT® modules, they ensure fast installation as well as precise and reliable measurement results over the entire operating temperature range.

System Applications

Key features of high voltage safe measurement systems

  • Certified high-voltage safety for the entire measurement system consisting of CSM's measurement modules and specifically designed multi-channel cables
  • Reinforced isolation up to 1000 V separates the measurement chain from the communication bus
  • 100% end-of-line testing of every module; including testing certificate
  • High measurement accuracy even under extreme temperature and environmental conditions
  • Available in MiniModule housings for mobile use in distributed measurement applications, and as 19'' slide-in modules for use in test benches and in vehicles
  • Specially developed sensor cables to ensure safe connections of sensors to measurement modules

CSM HV-measurement systems offer certified safety in accordance with EN 61010

By using CSM measurement systems, high voltage safe measurement chains can be set up, from the point of measurement to the data acquisition computer or logger. Each module is subjected to a routine test prior to shipment. The double-insulated multi-channel cables also play an important role in the system. These cables are pre-assembled with fully insulated plastic connectors. With each multi-channel cable up to four points of measurement can be safely connected to a measurement module. This reduces time and costs for cabling. In addition, the double insulation increases the protection against damage caused by chafing. The inner insulating layer is colored blue, so that damaged cables can be detected before a hazard to the user arises.
