A pressure sensor includes a housing, an isolator positioned at a first end of the housing, and a first cavity formed between the first end of the housing and the isolator. The pressure sensor further includes a second cavity formed in the housing and a channel with a first end fluidly connected to the first cavity and a second end fluidly coupled to the second cavity. A pressure sensor chip is positioned in the second cavity and includes a first diaphragm positioned at a top side of the pressure sensor chip laterally outwards from the second end of the channel to prevent a fluid from jetting onto the first diaphragm.
