Abstract

The invention discloses a device for solving external light interference on a photoelectric direct-reading meter, and relates to the technical field of photoelectric counter digital direct-reading devices. The device for solving external light interference on a photoelectric direct-reading meter comprises a casing and a counter; the casing is of a rectangle shape with side walls arranged at two ends; the inner part of the casing is provided with a receiving space which receives a plurality of character wheels, the center of each character wheel is provided with a hole, and the plurality of character wheels are sequentially, concentrically and equidistantly sleeved on a main shaft which is fixed on the side wall; a small plate is arranged between the character wheels and sleeved on the main shaft through a positioning hole on the small plate; and a photoelectric triode and a transmitting tube are arranged at two sides of the small plate. The light diaphragm of the device is arranged at one side of the small plate and totally encloses the photoelectric triode on the small plate, so that the reading error of the device for solving external light interference on a photoelectric direct-reading meter as the photoelectric triode of the counter is radiated by an external light source is avoided.

Description

technical field [0001] The invention relates to the technical field of digital direct reading devices for photoelectric counters, in particular to a device for solving the interference of external light sources for photoelectric direct reading meters. Background technique [0002] At present, there are many types of direct reading devices for photoelectric counters. Most of the hydrometers use the method of installing sensors inside the meters, such as photoelectric devices, which convert mechanical transmission into electrical pulse signals and transmit them to remote equipment. [0003] The core component of the device to solve the interference of the external light source of the photoelectric direct reading meter is a phototransistor, and its principle is to be in a conduction state under a certain intensity and a specific spectrum. There are various installation methods to solve the interference of external light sources of photoelectric direct reading meters. Many of th...
