Compact size, versatile mounting, and microprocessor based high performance capabilities makes the W Series an excellent choice for almost every application. The specifications of W Series signal conditioners are as same as F Series signal conditioners except for power supply voltage, second output and case width.

Details

  • Compact design for space saving. 72 mm (H) x 48 mm (W) x 127 mm (D).
  • Field configuration (WA5, WH2, WH5, WM1, WR5, WT5, WS1)
    A field configuration of the microprocessor based F Series are possible to set, change and monitor the range, zero/span, burnout, etc. from your PC (with VJ77 PC-based parameters setting tool).
