CTRS-CVPS010A Voltage Measurement Unit

Feature

The compact recorder CTRS-100 series is compact, lightweight, and shock-resistant and supports various stress measurements regardless of installation location, from environments where space is limited and exposed to vibration and shock, such as motorcycle running tests and actual ship tests, to tabletop measurements.

• Modular for easy expansion and measurement of up to 128 channels
• High installation flexibility
• Impact resistance: 490 m/s²(50 G)
• Simultaneous sampling of all channels at 20 kHz (4 channels)
• Measurement of 100 channel at up to 1 kHz
• Wireless real-time monitoring is possible (when using a wireless LAN unit)
• Compatible with CAN/CAN FD (when using a CAN input unit)
