DEVICE FOR MONITORING A LIGHT SOURCE OF AN OPTICAL SENSOR
First Claim
1. A device for monitoring a light source of an optical sensor comprising:
- at least one light source structured to emit transmission light in a transmission direction along an optical path, the at least one light source associated with a receiver structured to receive reception light, wherein the optical path extends from the light source through a measuring chamber Tillable with medium to the receiver; and
at least one monitoring unit adjacent the light source, each monitoring unit including a sensory unit configured to monitor the light source by receiving transmission light, wherein the sensory unit is oriented in the transmission direction and receives transmission light from a direction opposite the transmission direction.

Abstract
The present disclosure relates to a device for monitoring a light source of an optical sensor designed for determining a measured value of a measured parameter in a medium, including at least one light source for transmitting light along an optical path through a measuring chamber fillable with the medium, wherein the light source is associated with a receiver for receiving reception light, and at least one monitoring unit associated with the light source, with a sensory unit for monitoring the light source, wherein the monitoring unit receives transmission light, and wherein the sensory unit points in the direction of the optical path and receives light from the direction opposite the optical path. The present disclosure also relates to the use of such a device in an analyzer.
