Alat Ukur Ketinggian Muka Air
Brand : Hydrological Services – Australia
Model : AD375MA; AD375MAL
Special points of interest:
Deskripsi :
Instrumentasi ini digunakan untuk mengukur sekaligus memantau pergerakan muka air tanah.
Shaft Encoder model AD375MA dan AD 375MAL (brand : Hydrological Services – Australia) menggunakan daya yang sangat rendah, pengendalian shaft encoder dengan mikroprosesor yang didesain untuk penggunaan di lapangan untuk mengukur muka air pada sumur pantau atau pada Bendungan. Sirkuit internal CMOS memungkinkan Encoder untuk mengukur ketinggian dalam format porositas.
Absolute shaft encoder mengukur posisi sudut pada putaran shaft, jumlah inyal dan yang di keluarkan adalah 4 sampai 20 mA, SDI12 atau RS232. This signal relates to absolute level change from a set datum.
The signal can be viewed via the LCD display showing 4-20mA range and current water level and battery voltages
The shaft encoder can be float operated or connected to other servo mechanical sensors, chart recorders and weir gates with drive gears or chain and sprocket assemblies.
