These gauges measure pressure drops using precision machined metal piston encapsulated in a PTFE seal. This creates similar seal to a hypodermic needle. Despite the accuracy to which these seals are machined, there is still a small amount of leakage that occurs around the piston. This is why a piston gauge should not be used for liquid level applications or leak detection systems. Instead, they are recommended for filtration systems and flow rate applications.
• Lower costs
• Higher temperature capabilities
• Higher-pressure ratings
• Higher differential pressure ranges
This type of gauge utilizes a rubber diaphragm to measure pressure. This creates a perfect barrier through the gauge and allows for zero leakage. Because they create a perfect seal, they are best suited for liquid level applications and leak detection systems. As the diaphragm size increases, the sensing area also increases. This is why larger diaphragms are used on low pressure ranges, such as the 400DGC.
• No flow through gauge
• More sensitive measurement
• Lower pressure ranges available
