Abstract
A pressure sensor is provided with two supporting bodies (10,11) with plane supporting surfaces (12,13) between which a hose (14) is compressed or flattened. For measuring the internal pressure of the hose (14), pressure transmission means (17 or 22) is displaceable in a gap (16) that is arranged at a supporting body (10 or 11) adjacent to the compressed of flattened hose (14). The pressure transmission means (17 or 22) presses against the plane surface of the flattened-hose (14) and is supported on a force sensor (19). Thus, the deformation forces generated upon compressing the hose are eliminated for the measurement of pressure.
