Sentinel I28 Leak Detection System
Sentinel I28 is manufacturing’s most versatile and robust pressure decay and mass flow test instrument. It delivers durability and high test repeatability in a proven, standard platform and is configurable for a vast array of test types and options for pressure, flow, or vacuum testing. A multifunctional unit, it can be integrated with a PLC or operate on its own and control up to 5 tooling motions.
Sentinel I28 Leak Testing Technologies
The Sentinel I28 leak detection system is configurable for a variety of pressure decay testing or mass flow testing requirements. It provides storage for up to 99 pre-programmed test sequences and features a “Parent Program” that holds a customized test sequence for your multi-test application.
- Designed to deliver accurate, reliable, repeatable measurement
- Flexible and customizable to adapt to the needs of your production line
- Low Leak Rate Requirements (DP and DP leak rate)
- High Flow Measurements
- Sealed Part Testing
- Large Volume Part Testing
- Enhanced Fill and ExhaustPressure
- Easy to set up and operate, and now you can also manage the system from your PC with free CTSnet
- Integrate with a PLC or operate on its own with individual and linked tests in a user-programmed sequence
- Able to control up to 5 tooling motions with feedback
One instrument can control the operations of a test stand and replace a PLC for a cost-effective approach to testing!
