DataNet High-End Wireless Data Acquisition System

 

The DataNet adalah 16-bit data logging sistem dengan 4 masukan untuk pengukuran langsung dan pencatatan PT-100, termokopel (J, K, T), tegangan, arus, frekuensi, denyut nadi dan kontak kering. transmisi data dari unit ke komputer pusat menggunakan merek baru protokol ZigBee telemetri nirkabel. protokol ZigBee nirkabel menggunakan frekuensi bebas lisensi 2,4 GHz RF band. Setiap unit DataNet juga berfungsi sebagai repeater transmisi untuk unit tetangga, membentuk jaringan mesh handal hingga 65.000 node

Feature

  • Reliable transmission ensuring no data loss
  • Transmission range that can be constantly expanded by adding additional nodes
  • Minimal costs thanks to wire-free infrastructure
  • Portable units facilitating easy deployment in various environments
