Refractivity measuring element

Abstract

Abstract PURPOSE:To input a refractivity signal to another processing system in on-line system by detecting the position of a light beam refracted by a liquid sample by a line sensor. CONSTITUTION:A light beam from a laser source 1 is made incident slantly on a vessel 3 at an incident angle 45 deg.. Since front and rear surfaces of the wall of the vessel 3 are made parallel, the light beam is made incident on the sample from the direction parallel to that of the precedent incidence, refracted and received at the position P of the line sensor 2. If said beam is not refracted thereat, it advances along a dotted line and is received at a position P0. If the space between the incident surface of the vessel 3 and the sensor 2 is set to 30mm., a distance (d) between the positions P0 and P is indicated as a formula (n2: refractivity of sample). Since the output from the sensor 2 is an electric signal, it can be inputted to another processing system in on-line system.
