Digital level sensor

Abstract

The invention discloses a digital level sensor, which comprises a shell, wherein a circuit system, a suspension swinging component, a hydraulic micro displacement amplifying component and parallel light sources are arranged in the shell; the suspension swinging component comprises a swinging hammer, a T-shaped push rod and a swinging hammer revolving shaft; the swinging hammer is movably connected with the swinging hammer revolving shaft through the T-shaped push rod. The sensor is characterized in that digital signals are output, each sensing element outputs signals in the forms of switch pulses, and sampled data are only '0' and '1', so that the defect of fuzzy components in the conventional analog quantity detection way is overcome, the influences of various environment distribution parameters such as temperature, air pressure intensity, electric fields and magnetic fields are avoided, and the accuracy and reliability of detection are increased. Moreover, the digital level sensor is very high in resolution and accuracy, simple in structure and low in cost.

Description

technical field [0001] The invention relates to a digital level sensor. Background technique [0002] At present, when measuring the level state of engineering equipment, the bubble level is widely used (it uses the offset of the bubble relative to the reticle to judge whether the measured object is level by eyes), and its disadvantage is that the sensitivity is limited and cannot Generating electrical signals is not convenient for automatic measurement and automatic control. In some existing level sensors, physical quantity conversion is mostly performed in the form of analog quantity conversion (such as electrolytic, capacitive, etc.), and its output is analog. The sampling signal only changes in quantity but does not change in quality (mutant), it is difficult to resist external interference, internal drift, stability and reliability are difficult to meet the requirements of use. The reliability and stability of digital sampling sensors will be fundamentally improved, so...
