The invention relates to an optical measurement value pick up 1 with a measuring tube 26 in which a liquid column is located to which pressure can be applied for indicating the measurement value. Above the measuring tube 26, a light source 9 extending over its length is arranged and on the side of the measuring tube 26 opposite to the light source 9 an optical measurement-value pick up device 12 is arranged. This latter device is connected to a measurement value indicating device 14 via an optoelectronic sensor 13. <IMAGE>
