Point planimeter with electro-optical distance measurement system - consisting of sources and receivers with controlled electric positioning from slide moved along guide rail by motor

摘要: A planimeter has orthogonal or polar setting elements and associated measurement value electronic evaluation using optical detection of marked points. It is a rapid operation simple device working equally well for large small surfaces enabling automatic electrooptical distance measurement. The contains one more photocell receivers light sources (11) each positionally adjustable about fixed axis (g1) by an electric motor. source (d) mounted on slider (b) moved along guide rail (a) constituting the coordinate system abscissa motor (e) rotating first end rail. elastic drive current circuits are controlled detector relays.
