Waterproof industrial instrument capable of being easy to install

Abstract

The invention discloses a waterproof industrial instrument capable of being easy to install, and relates to the technical field of industrial instruments. The waterproof industrial instrument solves the problem that the installation of the industrial instrument has a large limitation due to the fact that an existing industrial instrument cannot be installed in case that rain or snow drips in an installation site. An outer protective shell is arranged on the exterior of an instrument panel, a sealing door is arranged on the front end surface of the outer protective shell, a sealing frame is arranged on the sealing door, and an observation window is arranged inside the sealing frame; one side of the sealing door is rotatably connected with the outer protective shell through hinges, a safetylock is arranged at one end of the sealing door, a lock buckle is arranged on the outer wall of the outer protective shell, and the safety lock on the sealing door is fixedly connected with the outerprotective shell through the lock buckle; and a water receiving tray is arranged on the upper surface of the outer protective shell, a drain pipe is arranged on the outer wall of one side of the waterreceiving tray, and positioning blocks are arranged on the inner wall of one side of the water receiving tray.

Description

technical field [0001] The invention relates to the technical field of industrial instruments, in particular to a waterproof and easy-to-install industrial instrument. Background technique [0002] Industrial instruments refer to gas and liquid turbine flowmeters, vortex flowmeters, electromagnetic flowmeters and other flow metering instruments, as well as pressure switches, differential pressure switches, pressure transmitters, differential pressure transmitters, liquid level switches, liquid level gauges, For industrial instruments such as temperature and humidity recorders, the performance indicators of the instruments are usually described in terms of accuracy, variation, and sensitivity in engineering terms. Instrument calibration instruments are usually three items of calibration accuracy, variation, and sensitivity. Variation refers to the maximum difference between the indicated values ​​of the instrument when the measured variable of the instrument reaches the same ...
