OMEGA’s LE902 series linear encoders work on the principle of counting pulses as a series of graduations move past a detector. These graduations are deposited on a low-temperature- coefficient glass (quartz glass) and counted using photodetectors. Because the glass is exceptionally stable, the pitch of the graduations does not change, resulting in inherently good long term stability. Signal conditioning is performed in an in-line electronics assembly which converts signals from the probe head to a digital format which can be plugged directly into a digital readout, computer or PLC via an RS-232 adaptor or the LDN101 network card.
