Patent attributes
A rinsing device for a sensor has a cylinderlike rinsing chamber which has an anterior chamber part connectable to a measuring fluid container and which is configured to receive an immersion tube that contains a sensor and is coaxial with as well as movable along the longitudinal axis L of the rinsing chamber. The rinsing chamber has a rinsing area delimited by an anterior ring groove and a rearward closure. A circumferential wall of the rinsing area has at least one inlet as well as a drainage outlet with an orifice opening for a rinsing medium. The anterior ring groove is aligned at an oblique angle (α) to the longitudinal axis, and the orifice opening borders on the most forwardly positioned location of the circumferential wall. The drainage outlet is directed at a forward angle from the orifice opening, and the circumferential wall has an internal diameter which increases continuously from the rearward end of the rinsing area up to the orifice opening.
