Differential Pressure Gauge – Vetrix Mag Gauge


  • Magnetic link drive mechanism eliminates friction caused by gear drive fundamentally.
  • No necessity to fill with liquid.
  • Motion of the pointer without inertia or drift.
  • No hysteresis.
  • Excellent anti-vibration and anti-shaking performance.
  • Positive, negative, or differential pressure can be measured multiple ranges are optional, minimum 0 ~ 30Pa to maximum 0 ~ 10KPa.
  • 2 sets of pressure ports (side, back) + 3 mounting modes = free and flexible application.
  • Excellent accuracy, reasonable price.

Vetrix Mag Gauge VDG series is widely used for measuring the fans or blowers pressure, filter resistant, wind speed, furnace gas pressure, Orifice pressure difference, bubble level, and hydraulic system pressure. It is also applied to regulate the air-gas combustion ratio and automatic valve or detecting the breathing, and blood pressure in medical equipment. There are some more applications like micro-electronics, aviation, and space, environmental protection project, biological, HVAC, food and beverage, and precision electronic processing.
