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.

Embodiments of the present disclosure are directed towards rotary variable differential transducers. The transducer may include a housing and an armature shaft included within the housing. The transducer may further include an input shaft configured to mate with an airplane shaft. The input shaft may be located independently from the armature shaft.

To enable fine adjustment of a sensor in a mounting device, a mounting device is provided for holding the sensor in an operating position. The mounting device comprises a base body having a first through-hole, a holding member having a second through-hole. The sensor is held in these through-holes by displacement of the holding member versus the base body and shifting the through-holes out of alignment. The holding member comprises an adjustment element, in particular a thread, which engages with an outer surface of the sensor in such a way that, when the sensor is rotated about a sensor central axis, the adjustment element causes the sensor to move along the central axis.

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.
