Abstract
A pressure sensing device particularly intended to equip a flowmeter of fluidic oscillator type, this device comprising a pressure orifice () linked to a measuring circuit () so as to send audible signals to a measuring membrane () fixed into a measuring cavity (), a deformation sensor () sensitive to the deformations of this membrane and capable of converting them into electric signals, and an electronic amplifier associated with this deformation sensor (), characterized in that the measuring circuit () comprises corrosion- and explosion-proof protection means () and filtering means () for filtering the audible signals so as to enable the disturbance frequencies of these signals to be removed.
