Unfortunatly we had yet another member loose his oil pressure and not catch it in time yesterday. Since I want to build several low oil pressure alarms for myself I wonder if any other people would like to purchase a complete kit? Volume purchases of every component may enable an end price less than the fuel you would burn running around trying to locate all the pieces and then you still have to design a lockout circuit for when the engine is not running.
It strikes me it will have to incorporate a system where it cannot activate without the engine running. Otherwise the high decibel level would drive you crazy everytime you turned on the ignition key or the engine off. Yet it has to be loud to get your absolute attention. Otherwise it is almost worthless in my opinion.
Low decibels could be masked by the radio is an example.On 240ds at speed it is in competition with the engine as well. These devices really give peace of mind in my opinion.
I have had them on other diesels I have owned. I can assure you that you do pay attention if it goes off. Primarily I believe installed for warranty protection by the manufactures. How could you take a seized engine back in and say you did not notice the oil pressure was gone. They are not going to buy it.
I also feel a high temperature coolant limit alarm might be a good ideal for those engines with aluminium heads. They are very simple and it could reduce the amount of cracked heads. These items are now long overdue in my opinion. Any thoughts?
