MPXV5004 Sensor Application question

HI,

I'm from a Commercial Glass & Dishwasher manufacture & we are looking at replacing our old diaphragm based pressure switches to the MPXV5004 pressure sensor with our control board, with reading the Datasheet it says:

"Internal reliability and qualification test for dry air, and other media, are available from the factory. Contact the factory for information regarding media tolerance in your application".

so my question is we can provide clean air to the sensor through an Air-Bell, but it wont be dry it will have around 60-70% humidity as we use hot water in the machines. will this affect the sensors reliability or longevity?

If so, are there other sensors that could be used? or a recommended way that we could connect the tube from the Air-Bell to the pressure sensor?.

Thanks

Damien

Hello Damien,

Thanks for using our community.

You could protect the sensor using a high viscosity silicone. Please, take a look at the following thread:
