Written by PIC Editor

HADRO Switch and Transmitter for Magnetic Level Gauges - explosion proof - intrinsically safe, HART, Profibus

Hadro manufactures Magnetic level gauges with

  • Reed or Microswitch
  • Reedchain transmitter with 4-20 MA analog output
  • Field-/Profibus or HART protocol
  • Intrinsically safe (Exi) or flame/explosion proof (Exd)

The housing can be made of Aluminum or stainless steel with IP68 and LCD or optical display.
