High-Voltage Safe Measurement Systems 
High-Voltage Safe Measurement Systems
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.
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.
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.
A specifically designed cross-section provides additional safety.
The HV BM Split Modules use the proven technology of the HV Breakout Modules for fast and precise measurement of internal conductor current, voltage and power even in confined spaces. HV BM Split Modules can be used to perform measurements in HV power cables.
The HV Breakout Modules (BM) are specifically designed for safely measuring directly from HV voltage power cables. Currents and voltages are measured directly and the raw data is acquired at up to 2 MHz per channel. With the Vector eMobilityAnalyzer software, which is optimally paired to the CSM HV Breakout Modules, real time power analysis is also possible.
The CSM HV DTemp measurement system is designed for the digital and precise measurement of up to 512 temperature measurement points via a single cable connection to the HV DTemp Central Unit.
With its HV AD measurement modules, CSM has designed a safe measurement system allowing for the use of standard sensors with analog voltage outputs as well as for direct voltage measurements in high-voltage environments.
The FL100 has been specifically designed for measuring analog voltages from IEPE sensors, such as triaxial accelerometers, in high-voltage environments.
CSM's HV PT measurement modules allow precise temperature measurements with PT100 and PT1000 resistance sensors in a high-voltage environment.
Safe temperature measurements with thermocouples on high-voltage components: the high-voltage-safe temperature measurement modules are specifically designed for the reliable acquisition of temperatures in electric and hybrid vehicles.
Type HV STG4 pro BS20
EtherCAT®-based measurement module for distributed use under demanding conditions in the high-voltage environment: robust, extremely compact and with 4 time-synchronous strain gauge inputs.
Safe high-voltage measurements in test benches: With the 19-inch slide-in modules, CSM has created an effective product portfolio for the safe measurement of analog voltages, currents, pressures, humidity and temperatures on high-voltage components in test benches and also in vehicles.
The high risk potential during measurements in high-voltage environments requires an enhanced safety awareness. This means: The user’s life and health should be put in the first place.
