CW Differential Pressure Gauge
The CW series differential pressure gauges are suitable for measuring the pressure difference of gases, liquids, or vapors from the same or different pressure sources, and can be used for corrosive media that have no corrosive effect on pressure sensing components. This gauge adopts double corrugated tube pressure sensing and is equipped with temperature compensation and single-sided overload protection device. Suitable for differential pressure measurement in high static pressure and low differential pressure systems, and can be paired with throttling devices to measure flow . It can also be used for liquid level measurement in closed containers. When the environmental vibration and medium pulse are large, oil filled vibration resistant gauges should be used to ensure stable readings and extend the service life. When introducing pressure, a three-valve group should be used to avoid damage to the instrument or inaccurate readings caused by unilateral overpressure.
