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

HV STG4 ECAT MM series

High-voltage safe measurement with strain gauges

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.

Key Features

  • 4 time-synchronous strain gauge inputs with reinforced insulation, galvanically isolated
  • Measurement data rate up to 20 kHz per channel
  • Support of full and half bridge strain gauges with 6- and 4-wire connection
  • High resistance to interference due to ratiometric measuring principle and configurable software filter

High-Voltage Measurements - Safe, fast and precise measurements with CSM

E-Mobility: Sicher messen an Hochvolt-Komponenten von Elektro- und Hybrid-Fahrzeugen 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.
