What used to be costly and time-consuming tasks has become efficient and convenient thanks to the mechanical revolution. Originally, nobody would have expected that devices like the Cyclic Pressure Control System would make industrial operations fast and reliable.


However, in the age of machines, there is some information you need to know. Specifically, you need to know which machines are tailored to your industry needs and best suit your operational requirements. So, today, let’s discuss two devices, namely, the Cyclic Pressure Control Structure and the Automated Burst Pressure Tester, to decide which one suits your particular demands.


So, without dawdling any longer, let’s get into the main discussion.


Automated Burst Pressure Tester or the Cyclic Pressure Control System? Which is better?


1. Automated Burst Pressure Tester (ABPT)


The Automated Burst Pressure Tester is widely used for determining the exact pressure at which a material bursts or fails to maintain its structural composition. This is determined within an atmospheric pressure range of 60,000 psi (hydraulic system) and 5,000 psi (pneumatic system). This machine is controlled by a microprocessor making it completely automatic, saving both time and labor.


Hydraulic ABPT


The Hydraulic APBT is a device that is different in terms of wetting liquid allowance as the working fluid includes only water, alcohol, and oil.


What’s more, there is no dedicated air requirement as the pressure cannot be limited at a range of 0-60,000 psi. This also affects the pressure transducers boosting their range to 0-60,000 psi and the accuracy rating all the way up to 0.01% FS.


Now because the PBT has an infinite maximum hold time, you get two power requirements. The first is the 110 VAC, 60 Hz, and the other is 220 VAC and 50 Hz. Other than that, the dimensions measure 51” H x 28.5” W x 26” D making this a bulky machine weighing around 300 lbs.


Yet, with a system resolution of 1/20,000 and a control accuracy rating of +/- 0.02% FS, the results are accurate and reliable. The last spec worth mentioning is the pressurization rate which is 0.1 psi p/sec – 200 psi p/sec.


Pneumatic ABPT


The other Automated Burst Pressure tester is the Pneumatic version. This one includes an air requirement of 80 psi and a pressure range of 0-5000 psi. Due to this range, the pressure transducers can only be as accurate as 0.01% FS.


Then there’s the pressurization rate of 0.1 psi per second that reaches up to 200 psi per second. However, with a system resolution of 1/20,000 (65,536 optional), the Automated Burst Pressure Tester can automatically control system accuracy at around +/- 0.02% FS.


The standard power requirements are 110 VAC, 60Hz, or if you want more OOMPH, there is also a 220 VAC, 50 Hz version. What’s worth mentioning, however, is that the dimensions of 51” H x 28.5” W x 26” D are the same as the hydraulic ABPT, yet the weight is only 150 lbs.


2. Cyclic Pressure Control System (CPCS)


The APP’s Cyclic Pressure Control Machine creates pressures cyclically at defined intervals. The minimum and maximum pressures range from 60,000 psi (hydraulic system) to an atmospheric pressure of 20 psi (pneumatic system). Similar to the ABPT, the CPCS is a device that is completely controlled by a micro-processor.


Now, let’s briefly discuss the specs for the Cyclic Pressure Control System so that you can understand how it works better and contrast it with the ABPT.


Hydraulic CPCS


The Hydraulic version only uses wetting liquids like alcohol, oil, and water. As there is no air requirement here, the pressure range can be exceeded to reach as high as 0-60,000 psi.


This enables the accuracy rating to be bumped up at +/- 0.02 % FS as the pressure transducers are set at a base accuracy rating of 0.01% FS. The system resolution remains at 1/20,000 (65,536 optional) regardless of the increased accuracy rating.


There are around 20 different pressure setting steps that make the Minimum Cyclic Time 0.02 seconds. The standard Hydraulic Cyclic Pressure Control System is an energy-efficient machine as it only consumes only 110 VAC, 60 Hz, and more intensively 220 VAC, 50Hz.


The machine is substantially heavy as it weighs 300 lbs., even though the measurements are reasonable at 51” H x 28.5” W x 26” D.


Pneumatic CPCS


The pneumatic CPCS in most of the specs is similar to the hydraulic version. The difference is its allowance of wetting liquid. This device allows any liquid to be tested, so you can essentially run tests with anything as long it’s in liquid form, of course. What’s more is that this time, an air requirement of 80 psi diminishes the pressure range to 0-5000 psi.


Yet, the accuracy stays at 0.01% FS, which is automatically bumped up to +/- 0.02 % FS through the system resolution of 1/20,000.


What makes the Cyclic Pressure Control System different from the Automated Burst Pressure Tester is the variety of pressure settings that it provides.


The CPCS consists of a whopping 20 different pressure steps that you can set depending on your testing requirements. This gives the operator control over the simulated test runs and garners unique results.


Moreover, with the power requirements of 110 VAC, 60Hz, and 220 VAC, 50Hz, these machines can be used for both lightweight and heavy testing.


That makes up for a Minimum Cyclic Time for the Cyclic Pressure Control System, only 0.02 seconds. The dimensions for the pneumatic version of the CPCS are 51” H x 28.5” W x 26” D. Yet, the weight is only 125 lbs., making this machine approximately two times lighter than the Hydraulic version.


More considerable details


CPCS is a highly accurate system that monitors pressure using its transducers for giving valuable based on that testing data to its operator. Moreover, with the inclusion of user-defined pressurization rates, holding times, and target pressure, you can also safely run fatigue tests using this machine.


Moreover, the robust build quality makes it so that real-world operating conditions like high temperatures can be simulated for creating distinct results under a variety of conditions. The windows-based software installed in the Cyclic Pressure Control System will develop spreadsheets of the test results that can be used for statistical analysis, report formation, etc.

If that was not enough, you could even change the reporting format to your liking for receiving even more meaningful results. The CPCS does not require much maintenance, making it a viable long-term investment for industries that conduct operations related to pressure testing.


The Automated Burst Pressure Teste, for the most part, possesses the same functionalities but only lacks customizable pressure settings like the CPCS.


Finally,


Both of these engineered machines are used in a majority of industries that conduct consistent research in developing and assuring the quality of operations. But, which one is better than the other?


Well, there is no black and white here; the machine that is relevant for you will come down to your industrial needs. Undoubtedly, both the above-mentioned pressure testers are the best in performing their own specific tasks.

 
 
 

Capillary Flow Porometer Testing Services has revolutionized how mundane industrial tasks used to be performed by making them modern, efficient, and cost-effective. However, capillary flow porometry is not the only service that has helped achieve industrial efficiency.


Mercury porosimetry is another highly used method for determining sample calculations. Yet, as both of these testing services are so frequently used, it’s best if you know which one should you choose for your industry. So, today, let’s discuss the differences between the Capillary flow porometry and Mercury porosimetry so that you can gain vital knowledge about the two.

Mercury porosimetry vs. Capillary flow porometer Testing Services


1. Mercury Porosimetry


This pore analysis forms the base for evaluating many of the materials, including catalysts, construction materials, sediments, porous plastics, ceramic green bodies, and porous plastics. The unique thing about Mercury porosimetery is its capability of analyzing a wide range of pore sizes.


These sizes start from small 3nm ones and go all the way up to 950 µm. This enables the test to cater to both the macropore regions as well as the mesopore regions. Furthermore, pore volumes are determined and measured by recording the amount of mercury that has intruded into the pore system. Later, pore size distribution is derived from the pressure dependence of filled pore sizes.


2. Capillary flow porometry


Capillary Flow Porometer Testing Services utilizes a technique that’s based on displacing the wetting liquid from the sample pores by applying gas pressure. The measurements include minimum, maximum pore sizes, bubble point measurements, pore size distributions, and through-pores in membranes, paper, filtration, ceramic, hollow fibers, etc.


During the process of porometry process emptying the corresponding pores via gas pressure is necessary for evacuating the liquid from the most constricted sample parts. It’s a challenging task as the constricted parts offer the highest resistance to wetting liquid removal.


How the calculation works are, first, the gas pressure is increased at a continuous and constant rate. The pressure rate can be modified by the user according to their experimental requirements. Afterward, the gas flowing through the sample is measured.


This is an efficient and effective method for measuring valuable sample data, which can then be used for analytical or quality control purposes. It’s important to note that complex structures require a considerable amount of tortuosity towards the pressure as longer pore paths cannot be emptied at certain pressure values.


The diameter needs to be scanned before allowing the gas to flow and displace the liquid through longer pore lengths. Yet, the consequences of calculating these pore lengths at times lead to miscalculations and incorrect reporting.


How do these differ?


Both the Mercury porosimetry and Capillary Flow porometry have their differences when it comes down to industrial usage. For instance, Mercury porosimetry can measure some of the largest pore sizes, while porometry cannot. But porometry can calculate a variety of data that the mercury porosimetry is limited by.


Conclusion,


There is nothing in black and white here. Both of these tests are valuable with respect to their particular uses and calculations. However, one thing is certain, the measurement methods, stability tests, parameters, gases, and liquids used in these tests are certainly valuable for analytical and research purposes.


The overall procedural and operational efficiency that you can achieve by implementing these tests will promote further developments.
