Water Gate Opening Indicator
Water gate indicator is important equipment for control of water gate on dam and river weir etc.
We have a lineup of indicators and converters which are suitable for purpose and site condition.
Signal Converter (CGDSW Series)
CGDSW series is a signal converter from Synchro to Digital for output to external equipment.
It has many useful functions for adjustment of gate opening indicator.
Non-linearity scale conversion table can be set up and it is suitable for the radial gate.
Features
- ・Conversion from the Synchro to the BCD signal (by Absolute value)
- ・Arbitray scale adjustment (Zero adjustment, Free scale, Level offset)
- ・Non-linearity scale conversion table can be set up easily by PC software and installed
it to the CGDSW through the SD card - ・Self-Diagnosing function (ERR code is displayed)
- ・Small size and lightweight
Available sites
- ・Water gate opening indicator which is using a synchronous motor
