Week #6: Complete Eaton Sensor Handouts.

[rjagodowski]

This week we will finish the discussion on the Eaton Sensors Handouts that we've been working on for the past few weeks.

We'll begin the lecture with a continuation of the 2, 3 & 4 wire sensor tutorials posted in Week #5.

Additonal information: Sinking & Sourcing Concepts from AutomationDirect.

You will be given a take-home assignment based upon these handouts which will be distributed on Tuesday, 3/3. If you are not in class on 3/3, please see your professor at your earliest convenience to get a copy of the assignment.

Our discussion of the enclosures for the switches & sensors brought up the safety concerns of dust present in the environment of an electrical spark. These links show some of the concerns.

Here's a video of a dust explosion demonstration from FM Global.

Here's the story and some pics of the Jahn Foundry dust explosion which happened here in Springfield in 1999.

Here's a pdf about dust explosions:

The used to be a demonstration video of a static discharge safety product for handling bulk dry materials from NewsonGale posted here. I'm searching for a new link. It shows the potential for explosion due to static charge build up.
