We offer custom design and
production of electronic equipment. Our firm has a rich experience with design of
precise analogue electronics, especially ultra-low noise amplifiers with noise deeply below 1 nV/sqrtHz,
ultra-low distortion circuits and oscillators with THD below 140 dB, high resolution AD and DA converters
with resolution up 26 bits together with digital and microprocessor
technology from 8-bit 8051 to 32-bit ARM processors. We are able to
develop Ethernet or USB DAQ modules or data loggers with SD
cards with capacity up 32 Gbyte.
A system for special chord resonant strain gauges for Nuclear power plant Temelin.
The system provides local or remote control via RS485 and consists of a measurement unit and
5 relay MUXes with a total capacity of 320 sensors. The system runs on both blocks since 2000.
