Complete I/O Support for Manufacturing & Final Product Testing

Posted on


Sealevel collaborates with a global leader that develops and manufactures safety products for professionals and facilities. One of their systems is specifically designed for gas detection in fire safety, mining, and building manufacturing applications.

These systems require extensive manufacturing line testing as well as final product testing. While tests vary for different parts of the system, primary tests include performance, accuracy, and timing of the sensors.

Due to the critical performance requirements, the company demands consistent, high-reliability products that can be applied to a wide variety of use cases.

The Solution

After initially selecting and deploying SeaI/O data acquisition modules, this manufacturer standardized on Sealevel products for all internal test platforms. Analog inputs on the eI/O 170E, SeaI/O 470E, and SeaI/O 570E are used to test sensors by taking measurements. During test, the sensors are deployed in a controlled environment to determine if the readings are accurate. The digital outputs on the eI/O and SeaI/O DAQ devices are used to actuate the test cycles. The inputs then conduct status information back to the host.

The Result

Sealevel’s wide range of products and consistent production quality successfully support the entire test cycle, ensuring finished systems are fully and accurately tested before deployment.
