HV STG4 ECAT MM series
High-voltage safe measurement with strain gauges
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.
Highlights
- 4 time-synchronous strain gauge inputs galvanically isolated
- Use standard strain gauge-based sensors from low-voltage applications safely in the HV environment
- Measurement data rate up to 20 kHz per channel
- Support of full and half bridge strain gauges with 6- or 4-wire connection
- Precise acquisition due to very small input voltage range
- Adjustable sensor supply voltages from 1 to 10 V
- High resistance to interference due to ratiometric measuring principle and configurable software filter
Description
Thanks to galvanic isolation, half and full bridges as well as standard strain gauge-based sensors from conventional low-voltage applications can be used in conjunction with special sensor cables. This simplifies the application and configuration, as you can rely on kown sensors and assure HV safety.
The measurement module HV STG4 pro BS20 is the high-performance variant among the HV-safe strain gauge measurement modules: With the wider input voltage range, small as well as large strains can be measured precisely.
