Measurement Technology

For more than 10 years, SAB Bröckskes has been meeting the challenges of developing and optimizing high-voltage cables as well as high-voltage measurement technology for components in electromobility. SAB has designed an HV measurement system with measuring modules from our partner CSM, which is ideally suited for mobile and stationary use in the field of electromobility (electric vehicles and hybrid vehicles). 

A safe and precise measurement of temperatures (thermocouples and PT sensors) and analog signals can be achieved by using CSM’s HV measuring modules in high-voltage environments. CSM’s HV measuring modules are tested to DIN EN 61010 ensuring the upmost safety. To address safety concerns, a measuring chain can be set up between the sensor and data collection point by special sensor cables and HV measuring modules. In addition, standard sensors for LV environments can be used for HV applications. The measuring modules are appropriate for use in road tests or for test benches as 19“ insert module.

Types include:

• HV Sensors Type K:  The sensors are used in HV components such as inverters, electric motors, HV batteries, and power electronics. The HV sensors are appropriate for stationary applications as well as for mobile test drives.
• HV Sensors Type K HT: HV type K sensors designed for high temperatures can be used in the thermal hardening process of insulating materials in E-units or other HV components.
• HV Sensors PT100/1000: Applications include temperature collection between the individual cells of a HV battery.
• HV Sensor Cable Acceleration & Strain Gauges: In order to measure acceleration and mechanical tension (strain gauge), HV sensor cables are needed.  In combination with the CSM measuring modules HV IEPE3 FL100 and HV STG4 pro BS20, reliable measurements at test benches or road tests can be performed.
• HV Analog Measuring: By using HV measuring cables combined with a suitable measuring module a voltage up to 90 V and a high voltage up to 1000 V can be measured in the stationary test field or mobile road test.
• HV Voltage Measurement: Two or three conductor HV measuring cables allow for the reliable measurements of DC and AC voltage in HV environments. The measuring cables are designed for an operating voltage of up to 1800 V.
• Highly Flexible HV Cables: Our highly flexible HV single conductor and sensor cables are an optimal feed line for electric motors or battery systems. With the use of silicone insulation combined with a fine stranding, the cables can be installed easily on test bench.
