TEL-310 Telecoordinometer (Telependulum) is designed to take automatic readings of the coordinates of pendulum’s plumb lines. It is characterized by high accuracy and resolution, wide measuring range and the possibility of measuring many steel wire simultaneously. TEL-310 is composed by three units: SUS (optical sensor unit), CUS (control unit with on board web server) and PWS (power supply unit). Moreover this instrument offers auto-diagnostic functions for measurements validation through a built-in high performance software. Either local readings by portable PC or remote operation via RS-485 serial interface are possible. TEL-310 is also implemented with 4-20 mA output for OMNIAlog network application.
