I'm looking for something to "add on" to my generator to shutdown when it over heats. Anybody have a suggestion where i can get it?
There is a temp sensor on my bus engine - it closes (ie. sends a pos. electrical signal) when the engine coolant reaches 95 deg C (about 202 - 204 deg F).
Depending on how your generator is controlled, it should be pretty easy to set up a control to shut it down (NC relay that opens when it sees the signal from the temp sensor to open a ground, or a NO relay that gets pulled in to close a fuel solenoid etc.) Unfortunately, I have no idea who made that sensor or what it's called and the company that made it is probably like every other British manufacturing company -- bought up by a Singaporean conglomerate 22 years ago and pretty much disappeared from view -- but there should be a N American made equivalent.
(But isn't there a control like this built into your generator anyway??? There is both an overheat and a low-oil-pressure shutdown built into my Onan.)
