Abstract

The invention relates to a photoelectric time measurement device of a liquid viscosity measurer. Based on a patent of ZL2012220329817.X, a laser indicator is inserted into a soft magnetic core cap; a small hole is longitudinally drilled in a soft magnetic core; a laser beam of the laser indicator penetrates through the small hole and reaches a steel ball through a flat concave transparent thin sheet; after being reflected by the steel ball, the laser beam is subsequently received by two photoelectric tubes of a computer time counter arranged on a scale plate; precise time counting is realized; and the photoelectric time measurement device is easy to operate and low in manufacturing cost.

Description

technical field [0001] The invention relates to a photoelectric time measuring device of a liquid viscosity measuring instrument, which belongs to the field of physical experiment measuring instruments. Background technique [0002] Patent No. ZL201220329817.X has solved the problems of traditional liquid viscosity measuring instruments, such as releasing and taking out the steel ball, ambient temperature, and the longitudinal axis of the measuring cylinder is not perpendicular to the plane of the base, but there are still problems such as inaccurate time measurement and difficult observation of the steel ball. Contents of the invention [0003] The technical problem to be solved by the present invention is: based on the patent No. ZL201220329817.X, a photoelectric time measuring device for a liquid viscosity measuring instrument is provided. After the concave transparent sheet is irradiated on the steel ball, the light beam is reflected by the steel ball and received succ...
