ante, pressure sender switch, to me and others I have worked with in the mechanical area, means when a temperature or pressure reaches a certain point, it turns on or off(receives no change in State until a certain point). And a pressure sender, means it sends a signal corresponding to the temperature or pressure that it is at. So I should be saying, pressure transmitter? Instead of pressure sender.
One, pressure transmitter will control the PWM. so it's varying voltage that corresponds to the pressure in the hydrogen line will control the power to the reactor via the PWM. I will also need another pressure transmitter, as a safety shutdown, to detect whether the pressure is too high or too low, and another safety shutdown to work in the same way for the reactor chamber, this is in case the one-way valve between the reactor chamber in the hydrogen line became blocked.
I like the way you are on the ball with safety ideas ante, I also have a mechanical over pressure release which will also release an enormous amount of energy, if the worst was to happen and there was an ignition spark within the chamber. As for where to release the hydrogen in such an event. Interesting enough it is extremely difficult to ignite hydrogen once released into the atmosphere. If you were to release hydrogen and turn off the source, and quickly try to ignite it,it is very very unlikely it would. The reason is, that hydrogen dissipates into the atmosphere extremely fast. If it was LPG leaking from under your hood, the danger alarms should be ringing. But just to make sure an electric fan can be used, that can be switched on in the event of a shutdown to help dissipate any released hydrogen,or the safety shutdown could be linked to the existing cooling fans of the vehicle on the radiator if fitted. There is another safety device idea that I have, but I am pretty sure this would be very difficult to put together and best left to a later time. The basic idea is although I do not want to attend it at this stage, is to compare the difference between RPM, hydrogen pressure and current being drawn by the reactor. At any given RPM the other two variables should correspond, within a certain degree range of error.
For now ante for experimenting, I can get away with one pressure transmitter, in the reactor chamber only water here, I won't use a one-way valve so the pressure in the hydrogen line and in the reactor will be the same, later on I will have to come up with the cash for a proper sender transmitter designed for hydrogen, these are available but cost an arm and a leg. Sorry for sending you astray ante, that sure is good for off the top of your head 8), I'm pretty sure I can use that circuit with the heat exchange system
.
You are pretty much on track, which is a little surprising considering how bad I am at explaining things :-\.
