Abstract
The utility model relates to a Hall linear micro-distance sensor, which is characterized in that the micro-distance sensor consists of a displacement pushrod, two magnets, an integrated linear Hall element, a measuring circuit, a return spring and a body case. The displacement pushrod is arranged closely on an object to be measured, the magnets are arranged internally at the two ends of the displacement pushrod, the integrated linear Hall element and the measuring circuit are arranged between the two magnets, and the return spring is arranged between the displacement pushrod and an upper end cover of the body case. The Hall linear micro-distance sensor has the advantages that the contact measuring method adopted can measure micro displacement change and the output voltage vary linearly with the object displacement, with high reliability, large variation range of the output voltage as well as convenient installation and debugging.
Description
Technical field
The utility model relates to technical field of sensor measurement, particularly the linear microspur survey sensor of contact Hall.
Background technology
At present, at the Hall linear transducer that the microspur fields of measurement is used, have only contactless, in measuring process, magnet need be installed on object being measured, in addition, existing Hall linear transducer, voltage output range is little, need the extra processing circuit module that increases, when actual measurement, no matter be to install or debugging, all very inconvenient.
The utility model content
The purpose of this utility model is to need extra interpolation equipment in order to overcome existing sensor when measuring, and provides Hall linear microspur sensor especially, and this is novel to be that a kind of linearity is good, reliability height, the touch sensor that output voltage range is big.
The utility model provides Hall linear microspur sensor, it is characterized in that: the linear microspur sensor of described Hall comprises displacement push rod (1), magnet (2), integrated linear hall element and metering circuit (3), back-moving spring (4), housing (5);
Displacement push rod (1) abuts against testee (6) and goes up installation, magnet (2) is installed in the inboard two ends of displacement push rod (1), integrated linear hall element and metering circuit (3) are installed between two magnets (2), and back-moving spring (4) is installed between displacement push rod (1) and housing (5) upper end cover.
Described integrated linear hall element and metering circuit (3) measuring element adopt integrated linear hall element H3057.
Described magnet (2) adopts two kicker magnet same polarities to install relatively.
Described displacement push rod (1) adopts the PVC plastic material.
The technical scheme that its technical matters that solves the utility model adopts is: displacement push rod (1) is installed near testee (6), when testee (6) when displacement changes, displacement push rod (1) is synchronized with the movement, make integrated linear hall element and metering circuit (3) produce relative displacement to magnet (2) and change, the output voltage that makes integrated linear hall element and metering circuit (3) produces linear change with the variation of object (6) displacement.
Advantage of the present utility model:
The contact type measurement mode can the Measuring Object micro displacement changes, the variation of the variation of output voltage and ohject displacement be varied to linear relationship, the reliability height, the output voltage variation range is big, installs, debugging makes things convenient for.
