Abstract: A sensor may include a sensing element retained within a storage compartment filled with a storage medium, which may also be used as a calibration medium. The sensing element can be moved from a first position in which the sensing element is exposed to the storage compartment, and a second position in which the sensing element can be exposed to a process medium. An actuator mechanism may be configured to engage a portion of the sensor to move the sensing element between the first position and the second position. The actuator mechanism may be controlled by an external system, and may include a rotary actuator such as a servomotor or a stepper motor to move the sensing element between the first position and the second position.

Abstract: A sensor may include a sensing element retained within a storage compartment filled with a storage medium, which may also be used as a calibration medium. The sensing element can include a sensing surface located away from the distal end of the sensing element, such that an inactive section of the sensing element can cooperate with a sealing member such as an O-ring to form part of the seal retaining the storage/calibration medium. The sensing element can be extended and retracted from the storage compartment to expose the sensing surface to a process medium, while preserving the storage medium within the storage compartment for post-measurement validation.
