CHEMICAL SENSING APPARATUS HAVING MULTIPLE IMMOBILIZED REAGENTS

摘要

A sensor system in a water treatment system has a housing, controller, one or more light sources, one or more sensors and one or more targets having an immobilized reagent thereon. Light source emits light energy into the housing that is incident upon the target with the immobilized reagent and the reagent being in contact with water from the system. The immobilized reagent interacts with a reactant in the water such that the interaction changes the state of the reagent. When energy from the light source is incident on the target with the immobilized reagent the energy shows a change detectable by the sensor such that the changed energy is detectable by and collected at the sensor and data on the energy is communicated to the controller. The data is then correlated as a representation of a desired variable to be measured for the water in the water treatment system.

1. A sensor system in a water treatment system, comprising:
a housing; a controller; an at least one light source; an at least one sensor; and an at least one target having an at least one immobilized reagent with the at least one light source emitting light energy into the housing that is incident upon the at least one target with the immobilized reagent and the immobilized reagent being in contact with a sample of water from the water treatment system, wherein the at least one target having the immobilized reagent interacts with a reactant in the water such that the interaction changes the state of the reagent and when energy from the at least one light source is incident on the at least one target with the immobilized reagent the energy from the at least one target having the at least one immobilized reagent shows a change detectable by the at least one sensor such that the changed energy is detectable by and collected at the sensor and data on the energy is communicated to the controller, the data is then correlated as a representation of a desired variable to be measured for the water in the water treatment system.
