DMC developed a complete hardware and software solution. DMC also provided complete project management from demolition of the existing system to the install and commissioning of the new system. The control system was implemented using a distributed application using Compact Fieldpoint Real-time, LabVIEW, and USB DAQ equipment. NI Real-Time Fieldpoint devices are used to communicate to mass flow controllers. These precisely mix varying concentrations of explosive gases, deploy them to the device under test, then ignite the interior of the device. The USB DAQ and signal conditioning board is used to collect high speed pressure data and detect explosion failures. A custom application in LabVIEW is used to perform all test management and test sample management.
Explosion-proof devices are defined as any device or container that, when saturated (inside and out) with an explosive gas or vapor, will not allow an internal explosion to propagate to the outside environment. This has obvious safety benefits in environments involving hazardous gas.
