Arrangement comprising an electrical printed-circuit board and an electrical pressure pick-up
First Claim
1. An apparatus made up of an electrical circuit board and an electrical pressure transducer which has, in a housing, a pressure sensor onto which the pressure to be measured is transferred by means of a fluid through a channel leading into the housing, said channel having a given fluid flow resistance, and from which there proceed electrical lines which project out of the housing as leads and are connected to the circuit board, wherein the channel is shielded by mechanical shielding means associated to the outer side of the housing so that the flow resistance for fluid entering and leaving the channel increases above said given fluid flow resistance of said channel.

Abstract
An arrangement made up of an electrical circuit board (7) and an electrical pressure transducer (1) which has, in a housing (2), a pressure sensor onto which the pressure to be measured is transferred by means of a fluid through a channel (5) leading into the housing (2), and from which there proceed electrical lines which project out of the housing (2) as leads (4) and are connected to the circuit board (7). The channel (5) is shielded on the outer side of the housing (2) so that the flow resistance for fluid entering and leaving the channel (5) increases.
