Abstract
Provided is a cleanable conductivity sensor and related methods having a distal sensing end in which active sensing elements are positioned and an outer fin specially configured to minimize unwanted interference without impacting the ability for automated cleaning of the distal sensing end. A rotatable wiper or brush may be periodically rotated over the distal sensing end, thereby removing unwanted biological build-up and avoiding fouling, thereby increasing the sensor deployment time without active intervention and maintenance.

A multi-parameter sonde comprising:
- a plurality of sensors, including at least one cleanable conductivity sensor, wherein each sensor comprises:
- a substantially planar distal sensing end formed from:
- a vertex region;
- a first inner end edge extending from said vertex region to a first inner end point;
- a second inner end edge extending from said vertex region to a second inner end point, wherein said first inner end edge and said second inner end edge extend in directions to define a vertex angle;
- and an outer end edge that extends between said first inner end point and said second inner end point;
- a first flat-faced inner surface that terminates at said first inner end edge;
- a second flat-faced inner surface that terminates at said second inner end edge;
- wherein said distal sensing end forms a portion of a circle;
- wherein in combination, each of said first and second flat-faced inner surface of a sensor are adjacent with another sensor first or second flat-faced inner surface to form a single continuous sensing surface having a continuous outer circumference in a single plane with less than 1 mm separation distance between adjacent sensors.
