Applications

Suitable for high static pressure differential measurement systems. It is commonly used in hydraulic systems to monitor pressure difference between pump inlet and outlet in order to detect leakage or blockage in the oil circuit. Its stainless steel construction also makes it suitable for humid environments and industrial applications with chemical corrosion risk.
