Incremental rotary encoder for measuring horizontal or vertical angles

Incremental rotary encoder

Rotary encoder especially for application in measurement instrument, such as theodolites, has binary coding circuit for coding two sinusoidal signals, and control unit with processor

Encoder and surveying instrument carrying magnetic encoder

Transit instrument for surveyor, has magnet arranged near magnetic sensor to reduce the detection errors of magnetic incremental rotary coder

Rotary encoder for surveying instrument has two sensors whose output voltage phase is offset w.r.t. each other by fraction of pi

Surveyor's transit with magnetic incremental rotary encoder has magnetic sensors staggered to each other to form phase angle in between to detect rotational angle of magnetic rotating drum

Schritt-Drehcodierer und Vermessungsinstrument mit einem Schritt-Drehcodierer Step rotary encoder and survey instrument with a step-rotary encoder

Vermessungsinstrument mit einem magnetischen Inkremental-Drehcodierer Surveying instrument with a magnetic incremental rotary encoder

Rotary encoder e.g. for surveying instrument has latch circuit which holds binary signal from one sensor when zero-point is detected at other sensor
