Deskripsi Signet 2552 Metal Magmeter Flow Sensor
Signet 2552 Metal Magmeter Flow Sensor dari Georg Fischer menampilkan konstruksi baja tahan karat. Nosepiece PVDF dan cincin-O FKM adalah satu-satunya bahan basah lainnya. 2552 dipasang dengan cepat ke outlet pipa standar 1¼ inci atau 1½ inci, dan dapat disesuaikan agar pas dengan pipa dari DN50 hingga DN2550 (2 hingga 102 inci). Panjang dua sensor memungkinkan fleksibilitas maksimum untuk mengakomodasi berbagai konfigurasi perangkat keras, termasuk katup bola untuk instalasi hot-tap.
Ketika dilengkapi dengan output frekuensi, 2552 kompatibel dengan instrumen aliran Signet bertenaga eksternal, sedangkan output digital (S3L) memungkinkan kompatibilitas multi-saluran dengan instrumen Multi-Parameter Signet 8900, 9900 atau 9950. Pilih output arus buta 4 hingga 20 mA untuk berinteraksi langsung dengan pencatat data, PLC, atau sistem telemetri. Fitur utama termasuk Deteksi Pipa Kosong, pemecahan masalah dengan bantuan LED, dan kemampuan rentang dua arah (dalam model 4 hingga 20 mA). Alat Konfigurasi Signet 3-0252 tersedia untuk menyesuaikan setiap fitur kinerja di 2552 sehingga dapat disesuaikan dengan kebutuhan aplikasi pengguna.
