A probe assembly for inserting a probe into a flexible or semi-rigid object is provided. The probe assembly includes an aseptic connector for coupling to the object, a probe sheath that extends longitudinally from the aseptic connector, and an actuator for deploying the probe within the object. The probe sheath has a plurality of concentric sheath elements and an inner longitudinal volume that is configured to permit longitudinal movement of the probe within the probe sheath. The actuator moves the probe longitudinally within the probe sheath by telescoping a first sheath element of the plurality within another sheath element of the plurality such that the probe is moved to a position sufficient to measure at least one parameter within the object.

A geared motor includes a stopper mechanism restricting the range of movement when the trailing gear rotates in a counter-clockwise direction. In the stopper mechanism, a first and a second angle ranges are obtained by dividing the range of angle of rotation of the trailing side gear by a virtual line passing through the center of rotation of the trailing side gear and the center of rotation of the driving side gear. In the first angle range in which the stopper touching part moves in a direction approaching the center of rotation of the driving side gear when the trailing side gear rotates in a counter-clockwise direction, the stopper touching part touches the part to be touched by the stopper. Thus, when the stopper mechanism is activated, the trailing side gear is subjected to a reaction force in a direction away from the driving side gear, making the meshing shallower.

The geared motor and pointer device are provided with a stopper mechanism which restricts the range of movement of the trailing-side gear when the trailing-side gear rotates in a counter-clockwise direction. In the stopper mechanism, the part to be touched by the stopper comprises a support-side protrusion which protrudes towards the center of rotation of the trailing-side gear, and the width dimension in the peripheral direction of the support-side protrusion is smaller on the inside in the radial direction than on the outside in the radial direction. As a consequence, even if the width in the peripheral direction of the support-side protrusion is increased to a certain extent in order to ensure strength, when the stopper mechanism is activated, the stopper touching part and the part to be touched by the stopper come into contact at a position close to the center of rotation of the trailing-side gear.

A powder dispersing device of a powder particle size distribution measuring equipment has a base, an elastic force generating assembly and a first housing. The elastic force generating assembly includes a bumping piece, a force applying board and a power transmission assembly. Two ends of the power transmission assembly are respectively connected to the bumping piece and the force applying board. When the force applying board is applied with a first displacement, the power transmission assembly actuates the bumping piece to generate a second displacement which enables the bumping piece to have a first elastic force. The first housing is formed with a through hole on a side surface for one end of the force applying board to extend out. The first elastic force of the bumping piece triggers the bumping piece to strike on any surface facing toward the inside of the first housing and touching the other end of the bumping piece.

A portable sensor includes a probe and a housing. The probe comprises a sensing part with one or more sensing elements, while the housing is designed to secure the probe such that the sensing part extends outside the housing. The portable sensor defines a gap between the probe and a surface of the housing that is configured to receive a rim of a liquid container such that the portable sensor can slot onto a rim of a liquid container, so as to allow hand-free measurements.
