Valcom – VPRT(F) series Pressure Transmitter untuk Tekanan Menengah Keatas

Pressure Transmitter Valcom

VPRT(F) series merupakan pressure transmitter dengan akurasi tinggi (Non Linearity: ±0.2%R.C.). Sensornya yang terintegrasi dengan diafragma menawarkan daya tahan dan umur yang panjang.

VPRT(F) Series ini dapat mengukur tekanan positif dan majemuk dalam kisaran 1 kPa hingga 100 MPa dari kapasitas pengenal (Kisaran kalibrasi: 0,5 MPa hingga 100 MPa) dan menentukan lebih dari 50% dari nilai kapasitas terukur dari rentang kalibrasi.

  • Akurasi tinggi (Non Linearitas: ± 0,2% R.C.)
  • Sensor mesin yang terintegrasi dengan diafragma menawarkan daya tahan dan umur yang panjang.
  • Output analog yang melimpah tersedia. [4 ~ 20mA (sistem 2 kawat, 4 sistem kawat), 1 ~ 5V, 0 ~ 5V, 0 ~ 10V]

Aplikasi Cairan

  • Air
  • Minyak
  • gas
  • Cairan lain yang tidak merusak SUS603 atau 15-5PH (Stainless steel yang dikeraskan)
