High-Voltage Safe Measurement Systems 
High-Voltage Safe Measurement Systems
HV STG4 BK20 and HV STG4 BS20 are EtherCAT®-based, robust and extremely compact measurement modules for strain gauge measurements in high-voltage environments with four time-synchronous strain gauge inputs and are excellently suited for distributed measurement applications under challenging conditions.
Thanks to complete galvanic isolation, half and full bridges and standard strain gauge-based sensors, which are normally used in conventional low-voltage applications, can be used as well if they are combined with specific, high-voltage safe sensor cables.
The module is especially suitable for applications in the fields of electric mobility – electric and hybrid vehicles – for stationary and mobile use.

Specifically designed to be operated in high-voltage environments, these measurement modules, equipped with 4 analog inputs, provide safety for analog voltage measurements, optional with galvanically isolated sensor excitation.
HV AD4 XW1000 measurement modules provide four analog inputs and are specifically designed for the measurement of high voltages in high-voltage environments.
Electric mobility is the future of transportation. The development of modern electric and hybrid vehicles poses new challenges for measurement technology. Not only must the measurement technology for eMobility match the traditional attributes of being accurate, mobile, and easy to use, it must also be safe for the users and the system. CSM high-voltage measurement technology ensures the safety of all measurement applications by means of a HV safe measurement chain from the sensor to the data acquisition.
Numerous measurement variables in vehicle development and testing can be recorded with sensors that reproduce their respective measured variable as an analog voltage. For example, distance, pressure, flow rates, moisture, vibration and noise can be easily measured.
