We need to build a small box for equipment monitoring (temperature, pressure diff., vibration, indication). Just a few discrete inputs/outputs, and analog inputs would be good enough. The hard part may be sampling an A/D signal at up to 30KHz, so having the I/O card do the sampling and buffer it would probably be necessary. The box would also need to have a supported wireless or a spare PCCard slot. Deployment would be in a shipyard in the Northeast, so being able to handle -30F to 100F would be necessary. Maintenance engineers would walk around on a daily or weekly basis and download sensor data from the monitors with a laptop (or some other handheld PC) for analysis (looking for equipment failures). Any ideas on hardware (SBC, I/O board)? -- Dan Eischen
