Immersion Testing

Testing for Cable & Harness Assemblies and Electromechanical Assemblies


Immersion Testing

Compulink can test cable and harness assemblies as well as electromechanical assemblies to customer requirements for IP67 and IP68. We have demonstrated the ability to test down to 20 meters for tactical military applications.

Component and Material Selection

Our engineering team can assist with component and material sourcing recommendations based upon years of hands-on problem solving in demanding environmental and immersion applications.

Process Refinement

Our expertise in sealing cable and harness assemblies for immersion has accelerated through our hands- on experience in process development to include low pressure molding, high pressure molding, epoxies, RTV’s, gasketing and sealing compounds.

The market for cable assemblies and electromechanical assemblies that have been tested to stringent immersion requirements has grown substantially. We have provided immersion tested cable assembly solutions for a variety of applications to include military communications, military computing, and tactical applications.

Dry Leak Testing of Electro-Mechanical Assemblies

Compulink Dry leak TestingCompulink’s Cincinnati Test Systems Sentinel I28 Leak Detection System provides the ability to test electromechanical assemblies to ensure compliance to the specified immersion requirements of your application.

The Sentinel I28 is configurable for a multitude of pressure decay and mass flow testing requirements. In addition, it can provide storage for up to 99 pre-programmed test sequences and can hold customized test sequences for multi-test applications through its Parent Program capability set.

This single station air flow and leak detection system features a high contrast 24-bit color display with XY graphing capability for pressure, loss, or flow.

Wet Leak Testing

Compulink Immersion Tank testerImmersion Leak Test Pressure TankCompulink can perform wet immersion testing to include immersion to actual depth in a controlled atmospheric tank, simulated depth in a pressurized tank, and immersed and pressurized bubble testing. Validation of sealing can be conducted through observation of bubbles, weight analysis, disassembly and continuity and high voltage electrical testing.  Methods for test and validation are tailored to the specific design and specification requirements.
