Compact and lightweight Suitable for an on-board and mobile application.
CDV-400B series is a multi-channel signal conditioner system to measure physical quantity such as strain, acceleraton, load, voltage and frequency. Several conditioner cards can be mounted to the unit base to configure an optimum measurement system for any application. The system operates on DC power, also an AC adaptor SA-6A is available as option.The compact and lightweight design makes the system suitable for measurement on motor bicycles, tractors, boats and wheelchair.
Features
- 5 different kinds of conditioner units are available for configuration of an optimum system for the measurement purpose.
- Signals of multiple units can be output through a single concentrated connector.
- Simultaneous calibration of all channels is possible through the unit base.
