High-Voltage Safe Measurement Systems 
High-Voltage Safe Measurement Systems
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.
CSM therefore strongly recommends to check the high-voltage isolation of these measurement modules on a regular basis in order to ensure their operational safety at all times. This applies in particular, if high-voltage measurement modules are exposed to strong external influences.
For this purpose CSM developed the High-Voltage Isolation Testing Station, consisting of
This station provides options for testing the high-voltage isolation of CSM measurement modules directly on the customer's premises. This is cost-saving and improves the availability of the high-voltage measurement modules as it is no longer necessary to send them to the manufacturer for testing. During a high-voltage isolation test, the isolation of a measurement input is tested against all other measurement inputs, as well as against the housing, the power supply and the CAN bus.
Safe temperature measurements with thermocouples on high-voltage components: the high-voltage-safe temperature measurement modules HV THMM 4 and HV TH-TBM 8 are specifically designed for the reliable acquisition of temperatures in electric and hybrid vehicles.
Safe acquisition of analog signals on high-voltage components: With HV AD measurement modules, CSM has created all-round measurement modules for standard sensors with analog voltage outputs in high-voltage environments.
CSM's measurement modules HV PT MiniModule (HV PTMM) and the HV PT test bench module (HV PT-TBM) allow precise temperature measurements with PT100 and PT1000 resistance sensors in a high-voltage environment.
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.
E-mobility: Safe measurements on high-voltage components of electric and hybrid vehicles; in distributed applications and in test benches. CSM measurement systems offer certified safety for the measurement of temperature, voltage, humidity, etc. in high-voltage environments.
