6 things you didn’t know you could do with the Sentinel I28

quantri — Tue, 19 Apr 2022 07:16:14 +0000

Sentinel I28 is a popular instrument for use by our customers. It is one of the most advanced multi-functional test instruments on the market. It is a flexible instrument, configurable for a variety of pressure decay and mass flow testing requirements.

This flexibility means there are many test types made possible with the I28 that manufacturers may not realize. Let’s explore some of these, below, to make sure you are getting the maximum benefit out of your Sentinel I28.

1. Run an occlusion test with Sentinel I28

Many manufacturers don’t realize they can run an occlusion test with their Sentinel I28. Backpressure occlusion blockage testing is one of the popular methods of blockage testing, used predominantly to check tube sets and valves in the medical device manufacturing industry.

This test type utilizes a constant user-regulated air pressure delivered by the test instrument to the part under test. The test is simple and has only one operating step where at the end of a test timer, the backpressure is recorded and must remain below a high backpressure limit (as defined by the user) to pass. Alternatively, the logic may be reversed to verify that the part does not vent to atmosphere and is closed.

2. Conduct a pressure decay test and mass flow test with same instrument

Another helpful feature of the Sentinel I28 is that it can perform pressure decay testing and mass flow testing using the same instrument.

This unique capability is particularly helpful in ensuring you are using the technology that provides you with the most accurate and repeatable test results. Using the same instrument, you can conduct a Gage R&R study, testing your instrument using pressure decay, then mass flow, to identify the most effective test type.

3. Control up to 4 different pressure sources

The Sentinel I28 is equipped to control up to 4 different pressure sources. This is particularly helpful when conducting multiple tests on the same part that require both high and low pressure.

For example, you could run an occlusion test at low pressure and a pressure decay test at high pressure, at the same station, all with the same device. The instrument will be able to pull up the required pressure, with manually controlled regulators.

Instead of having to use different instruments for each part during testing, the Sentinel I28 offers a simple way, right out of the box to run multiple tests, controlling itself, saving you time and money.

4. Control up to 2 different electronic regulators

Electronic regulators are becoming more and more common in production as a way to ensure a consistent, accurate test every time.

The Sentinel I28 is unique in that is allows you to control up to 2 different electronic regulators at the same time. This means that you can set up one regulator for vacuum and the other for pressure, all with the same instrument.

5. Automate test pressure selection before test

Manual test pressure selection on the line can lead to inefficiencies and false results. The Sentinel I28 delivers a solution, equipped with technology that allows it to automate test pressure selection on a line with varying parts and designs.

When connected to an electronic regulator, the Sentinel I28 automatically selects the right settings for your test, which can allow for full automation, depending how you want to set up your line.

6. Store barcode-scanned information

The Sentinel I28 is equipped to allow for the scanning and storing of barcode information, as can be required on the manufacturing line.

Once your barcode scanner is plugged into the Sentinel I28, simply scan the barcode, press start on instrument, and the information scanned will be stored along with the associated test data. The operator can then be presented with all of this information in a character string at the end of the test.

This allows you to reference test time, date, operator, leak rate, accept/reject, etc. in association to specific parts that have come down your line, by serial number, etc.

The Sentinel I28 allows for up to roughly 5,000 pieces of data to be stored on the device, or it can be connected to other data collection devices you may be using on your line.

FUNCTIONAL TESTING SYSTEM and EQUIPMENT

quantri — Mon, 06 Jan 2020 15:30:10 +0000

Functional testing is critical to the performance of any complex system, as it checks the system against its design documents and specifications to ensure that it performs all of its functions as it should. And, essential to all functional test systems is the ability to collect and process data. Whether you need to test and calibrate equipment or establish characterization curves on parts tested via a hydrostatic leak test, Cincinnati Test Systems (CTS) has the experience and expertise to provide functional test systems that are custom-tailored to your application.

We design, manufacture, and support custom functional test systems and lean cell testing solutions. We are a recognized global leader in functional test system technology, providing turnkey solutions that include precision instrumentation and information software written by CTS’ expert engineers, and are supported by a team of technical application specialists.

Proven Engineering, Design Versatility & Extensive Experience for Functional Test Systems

CTS’ expertise crosses multiple business sectors, allowing us to provide customers with test solutions designed for their specific market or application. We offer a variety of integrated technologies including:

Equipment Calibration Test Systems

CTS Equipment Calibration Test Systems allow users to test their parts to ensure that they conform to manufacturer specs and are sized to meet production requirements. These calibration testing solutions can be used to test electrical, mechanical, and electromechanical systems via resistance, pressure, and/or vacuum testing. We can provide the custom equipment calibration system you need, from a simple tabletop device to a fully-automated multi-station system with advanced capabilities.

Dunk Testing Systems

Our dunk testing systems are used to test parts to ensure they conform to manufacturer leak specifications and are sized to meet production requirements. Dunk testing involves submerging a gas-filled (usually compressed air) part in water to identify leaks via a stream of bubbles. These systems use pressure decay leak testing to measure leak rates in vessels of all types. A variety of options, including automation and more, are available to create the perfect dunk test solution for your application.

Flow Testing Solutions

CTS provides the industry’s most reliable and effective flow testing solutions. We design and build flow testing systems that utilize a variety of flow test techniques, and will work with you to determine which option will provide the best results in your application. We can provide solutions for flow path size testing, flow leak testing, and more. These functional test systems are designed for easy integration into your production processes for fast and efficient testing.

Fluid & Air Burst Test Systems

Burst testing uses pressurized fluid or compressed air to apply controlled pressure to the exterior of a part to ensure that the part functions properly and doesn’t leak at the prescribed pressure level. Our fluid and air burst test solutions are designed to operate in your specific test environment, and at the pressure level(s) your products require. Custom part fixturing, test connectors, and other features ensure that your fluid/air burst test system delivers the right performance for your application.

Hydrostatic Leak Test Systems

Hydrostatic leak testing is used to check a part vessel or cavity for leaks and test its structural strength and pressure tightness. An internal cavity pressure test uses a non-compressible liquid, a volumetric displacement sensing device, and a calibrated test instrument to detect leakage. CTS hydrostatic leak test solutions utilize calibrated volumetric fill testing to identify leaks via pressure drop. These functional test systems can also be used to perform burst, leak, flow, equipment calibration, or integrity testing.
