Also a sensor carrier for the measuring apparatus and a cleaning method.
Claims9
A measuring apparatus for measuring chemical or physical characteristics of a fluid, the measuring apparatus comprising:
- a sensor carrier having a fluid channel configured to feed a fluid through the sensor carrier;
- a measuring window forming a wall area of the fluid channel;
- a sensor means configured to measure at least one chemical or physical characteristic of the fluid within the fluid channel through the measuring window,
- and
- a cleaning device configured to remove fluid deposits from the measuring window,
- wherein the cleaning device has a wiper element, which is guided, at least partially, inside the sensor carrier opposite to the measuring window, and
- wherein the wiper element is configured to move relative to the measuring window in at least two directions such that the wiper element touches the measuring window.
A method for cleaning a measuring window of a fluid channel, wherein the measuring window forms a wall part of a fluid channel inside a sensor carrier, the method comprising the steps:
- extending a wiper element of a cleaning device from an idle position inside the sensor carrier in a working position, in which the wiper element touches the measuring window of a sensor means in the senor carrier;
- moving the wiper element on the measuring window until fluid deposits are removed from the measuring window;
- and
- retracting the wiper element back in the idle position.
