LE902 Series

Linear encoders are compatible with DR601 meters. See page J-12.

OMEGA’s LE902 Series linear encoders count pulses as a series of graduations move past a detector. These graduations are deposited on a low-temperaturecoefficient glass (quartz glass) and counted by photodetectors. Because the glass is exceptionally stable, the pitch of the graduations does not change, resulting in longterm stability.

Signal conditioning is performed in an in-line electronics assembly that converts signals from the probe head to a digital format. This format can be plugged directly into a digital readout, computer, or PLC via an RS232 adaptor or the LDN101 network card.
