Sensor Ketinggian Air Banjir Quartz Type Water Level Gauge OPQS2 Series
SSensor ketinggian air seri OPQS adalah sejenis “tipe Quartz pressure”, untuk meningkatkan proteksi petir. Sensor ini hanya menggunakan serat optik untuk kabel transmisi data dan power supply listrik dengan memasang “konvertor optical-electric yang sangat kecil” di dalam sensor. Baru-baru ini di Jepang, jenis ini telah digunakan untuk pengendalian bendungan dan prakiraan banjir serta sistem peringatan.
Tekanan air, bervariasi seiring perubahan ketinggian air, diukur dengan osilator kuarsa, yang frekuensi osilasinya diubah menjadi sinyal optik (SM) pada konverter E/O di dalam sensor untuk transmisi. Sumber daya sensor menerima sinar laser, yang dipancarkan dari sumber cahaya yang terpasang pada pembuat kode pengukur ketinggian air, pada catu daya listrik optik untuk menghasilkan tenaga listrik. Bebas dari lonjakan petir karena kabel nirkabel (serat optik) digunakan untuk transmisi data antara sensor dan konverter sinyal.
Pengukuran dengan akurasi tinggi, tanpa kesalahan konversi yang disebabkan oleh perubahan sekuler yang biasa terlihat pada diafragma.
Rentang pengukuran yang luas, dari 10m hingga 70m, cocok untuk pemantauan air sungai dan juga bendungan.
