Patent ID: 8429952

Claim:
A probe with antifouling control, the probe comprising: a first portion; a second portion, wherein the first portion and the second portion are configured to move between an open position and a closed position; a sensor configured to measure an attribute of a fluid when the first portion and the second portion are in the open position, wherein the first portion and the second portion cooperate to cover the sensor in the closed position; antifouling components that inhibit fouling of the sensor, wherein the antifouling components include: a wiping component, wherein the wiping component moves across the sensor when the first portion and the second portion move between the open position and the closed position; and an antifoulant component configured to deliver an antifoulant to the sensor; and a feedback component, wherein the feedback component cooperates with at least some of the antifouling components to clean at least a portion of the probe, wherein the feedback component includes a controller that measures a current or voltage required to move the first portion and the second portion between the open position and the second position, wherein the controller repeatedly moves the first portion and the second portion back and forth two or more times when the current or voltage exceeds a threshold current or threshold voltage such that the wiping component scrubs the portion of the probe.
