A new type of twodimensional horizontal sensor

A new type of highprecision sensor twodimensional horizental sensor is described which gives a DC mV output signal. The measurement sensitivity is 05mV/arcsec over a range of ±200 arcsec. The accuracy is 1 arcsec and the response time 1 second. This sensor can be directly connected to an autodetect system, or to a secondary meter to form a horizontal meter.
