Includes a variety of our filter indicators, a precision gauge, and a manual.
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
• Can have a zero center dial
By measuring a pressure drop across a filter, operators can get a visual indication about how dirty their filter systems are. Common accessories include color bands and electrical switches for alarms.
Measuring liquid levels for cryogenic storage vessels is one of the largest developing applications for differential pressure gauges. Common accessories include panel mount dials, dense mark dials, and vertical calibration
Using the Bernoulli Principle, differential gauges can convert pressure drops to flow rates. We can customize gauges to your exact flow data. Common accessories include pipe mounting kits and dual scales
A differential gauge is a great tool for detecting leaks in systems. A reference tank can be used to test leaks in storage vessels or you can use a gauge over a length of plumbing to detect a pressure drop.
Glycerin or silicone dial case fills for reducing vibration and preventing fog buildup.
2″ pipe or wall mounting brackets that work with all precision gauges and ease installation.
1 or 2 SPST or SPDT switches that can be set and field adjusted to the pressure range.
Detect pressure peaks throughout the day without needing to always watch the gauge.
Use one gauge to monitor multiple devices with a portable kit
Distributors and manufacturers can use their logo for free on any precision gauge
Hardware can be supplied to directly connect to large bag housings and filter heads
