Abstract
The utility model relates to a double-channel weighing sensor, which includes a shell; the elastic body of the sensor is positioned in the shell; both ends of the elastic body of the sensor protrude out of the end surfaces of the shell; and double-channel outputs are symmetrically arranged on the side of the shell. The double-channel weighing sensor has the advantages of simple structure, good appearance, low fabrication cost, high precision, good stability, modularized design and easy installation.
Description
Technical field
The utility model relates to a kind of binary channels LOAD CELLS, belongs to sensor and makes the field.
Background technology
Granted publication CN2588337Y, title " a kind of LOAD CELLS ", this LOAD CELLS is provided with U-lag on the recessed annular between the annular strain face at loading end and around the loading end setting, go up annular strain basifacial and be provided with annular U-lag down, the loading end bottom is provided with blind hole, annular strain face under between blind hole and the following U-lag being, the lower sidewall of extending downwards from last annular strain face outer shroud forms annular support, posts tangential foil gauge respectively on the upper and lower annular strain face.Its weak point: the one, complex structure, manufacturing cost height; The 2nd, adopt an output channel, precision is not high, poor stability.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design the binary channels LOAD CELLS of a kind of simple in structure, low cost of manufacture and output signal long transmission distance.
Design proposal: LOAD CELLS is to utilize the resistance-strain principle to constitute, and resistance strain gage is attached on the elastic body neutral surface, forms the bridge measurement loop.Do the time spent when sensor is subjected to external force, elastic body produces corresponding deformation, and the resistance-strain value changes, and makes the bridge circuit out of trim, and supplies under the bridge voltage effect in the external world, and electric bridge is exported uneven electric signal.This signal magnitude is directly proportional with the size of external force.By standard metering equipment, can the suffered load requirement of determination sensor.On structural design, sensor elasticity is positioned at the end face that two of shell and sensor elastomer protrudes from shell, adopt laser bonding between sensor elastomer and shell, reduced elastomeric little distortion to greatest extent, and binary channels output is symmetricly set on the sidepiece of shell.Consider that sensor is installed and external force to elastomeric influence, adopt modular design, easy for installation and have a stop means.
The utility model is compared with background technology, and the one, simple in structure, outward appearance is beautiful, low cost of manufacture; The 2nd, precision height, good stability; The 3rd, modular design, easily installation.
Description of drawings
Fig. 1 is the structural representation of binary channels LOAD CELLS.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.The binary channels LOAD CELLS, it comprises shell 2, sensor elastomer 1 is positioned at the end face that two of shell 2 and sensor elastomer 1 protrudes from shell 2, resistance strain gage is attached on the elastic body neutral surface, form the bridge measurement loop, side sensor elastic body 1 and 2 on shell that binary channels output 3 is symmetricly set on shell 2 adopt laser bonding.
What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.
Claims (2)
1, a kind of binary channels LOAD CELLS, it comprises shell, it is characterized in that: sensor elastomer is positioned at the end face that two of shell and sensor elastomer protrudes from shell, and binary channels output is symmetricly set on the sidepiece of shell.
2, binary channels LOAD CELLS according to claim 1 is characterized in that: adopt laser bonding between sensor elastomer and shell.
