OM 502LX
OM 502LX
5 digit LINEARIZER
Type OM 502LX is a precise 5 digit panel programmable linearizer for non-linear input signals. Using the OM Link programme, linear interpolation up to 256 points and 16 charts can be implemented. The instrument is based on a single-chip microcontroller with a fast 24-bit sigma-delta converter, which ensures good accuracy, stability and easy operation of the instrument.
