Absolute pressure in a turbo engine throttle body

[thalesmaia]

Hi, I built a circuit to supplement fuel and control a turbocharger for a aspirated engine. The project started last year and I already got 2 dead sensors after some time operating.

I'm using:

MPXH6250AC6T1

Any idea what might be?

Sincerely

Hi,

The MPXH6250AC6T1 uses a standard Fluorosilicone gel that is not supposed to survive exposure to fuel vapor or direct contact with fuel. For more information, please refer to our AN3728.

A better option is using the MPXHZ6250AC6T1 with an improved Media Resistant gel that is supposed to survive exposure to fuel vapor, but not direct contact!

Best regards,

Tomas

Perfect!

From time to time, choosing the right sensor is always a challenge. I remember now: I chose the only one available in Mouser.

Also, reviewing the datasheet, I notice some standard info that get the designer confused (same standard info for the datasheets):

Anyway, I thank you for the help.
