Profile: International Electronic Machines Corp. develops, manufactures, and markets rugged imaging & sensor-based systems for transportation security, safety & metrology. We design and market unique rugged metrology & datalogging products to the railroad industry. We specialize in integrated systems development ranging from custom design of specific cameras, optics, and sensors, to specific software solutions for safety or security monitoring, to wide-area networks capable of delivering timely and appropriate decision support information. We also specialize in rugged instrumentation design and unique multispectral imaging & sensor solutions, especially those having to do with smart sensors and sensor fusion approaches. The Mini-EWG integrates the controller, keypad, sensor, and LCD screen into a single unit, weighing less while offering greater maneuverability, versatility, and improved operability. A user-friendly menu displays simple easy-to-follow instructions. Our rugged design allows for the tough environment and climatic conditions in which the Mini-EWG needs to endure, as well as insuring that no measurements are taken until it is properly placed on the wheel. The patented Mini-EWG provides consistently accurate readings up to 1/64th of an inch. Wireless transmission of the stored data improves overall efficiency, eliminates errors, and reduces unnecessary costs.
