I have noticed at one of my applications that the pressure sensor I used to measure the Oil pressure for a diesel IC Engine is causing (?) the failure of the the IC 7805 regulator which is being used to power the sensor with the +5 V DC supply. The sensor make is not known but the Land being Denmark. Well; the sensor has three pins a Supply (+5 V) a ground and the third being the signal output. I'm reading the signal in with an Op amp stage. But the culprit is the 7805 which, without any signs/symptoms of heating or burning gets off the bussiness. I will be thankful to anybody suggesting a check or solution on this. Are these type of sensors Piexo type sensors? What's the Pieo type Pressure sensor though? I have heard and seen those working on strain gauge principle.
