Abstract
The utility model discloses a weight type intelligent charge level probe unit with high accuracy, which can continuously and simultaneously measure liquid levels and material levels in real time. A pulley is fixed to the upper part of a support post which is movably arranged in a bracket, and the lower part of the support post acts on a pressure sensor. After a rope which is connected with a measuring heavy hammer passes by the pulley and another friction wheel provided with a shaft pulse coder, the rope winds a roller driven by a motor. Voltage signals output by the pressure sensor which can reflect the size of tension on the rope and pulse output by the shaft pulse coder which can measure the movement distance of the weight are sent to a single chip microcomputer to be processed and analyzed, and a measuring result is displayed. The motor can be automatically controlled to carry out forward rotation, inverse rotation and stop rotation.
Description
The utility model relates to a kind of level indicator, relates in particular to a kind of Weight type charge level detection instrument.The present method of measuring material level has a variety of, can be divided into by principle; Pressure type level-sensing device, capacitance level meter, radioactivity level-sensing device, Plumb-bob Material Level Meter or the like.
The pressure type level-sensing device belongs to the level-sensing device of one-point measurement, at the sidewall of feed bin a microswitch is installed, as material high when to a certain degree being pressed onto microswitch the generation switching signal.It is constant that this mode requires material single-size shape and severe, and the spacing measurement of can only fixing a point.
Capacitance level meter is an instrument of measuring material level by the electric capacity (one of them electrode also can be a chamber wall) that detects residing two interpolars of material.This instrument is subjected to the influence of material bigger, unstable properties, and when density, humidity, the temperature of the material Shi Douhui that changes influences measuring accuracy, even can't operate as normal.
The radioactivity level-sensing device is to utilize more radioisotopic characteristics and finish mix position meter.Radioactive isotope is meant the isotope that can radiate some particles and change in quality into another kind of steady state (SS).When radioisotopic ray was injected certain thickness medium, only some particle can be penetrated over, even is all absorbed by medium.The intensity that penetrates weakens along with the increase of the thickness of medium.The radioactivity level-sensing device is usually as the spacing level-sensing device of switching regulator.Because radioactive ray are harmful,, its using dosage and installation, use, maintenance etc. handle by relevant regulations so being wanted strict.This level-sensing device equipment complexity involves great expense.
Existing Plumb-bob Material Level Meter is mainly graded and is formed by servomotor part, weight part, balanced lever, pulse forming panel, control part.This Plumb-bob Material Level Meter is to drive balanced lever by weight to control a reversing switch, and controls the forward or reverse of motor with this.When measuring, the initial position of weight is in the top of feed bin, because this moment, weight was unsettled, balanced lever is downward-sloping under the effect of weight, and the drive reversing switch just changes motor.When weight ran into material level, because the holder power of charge level makes weight weightlessness reduce the pulling force of rope, balanced lever restored under the effect of spring, and reversing switch is incorporated into the inverted running position, made the motor counter-rotating.Unison counter writes down the umber of pulse during this and shows.Last weight is got back to initial position.The force measuring machine complexity of this mode, action are insensitive, out of control easily, need often to adjust, and can only measure the material level of single character, and measuring accuracy is also not high enough.In addition, each weight that finishes of measuring is got back to initial position always, makes measuring period long, is unfavorable for reaching the requirement of real-time monitoring.
The purpose of this utility model is the Weight type intelligence charge level detector of a kind of material level of continuous coverage in real time of design, this detection instrument can be under any abominable, complex environment steady operation and do not influence its measurement performance, can measure the material level of the solid of Any shape and density.To solid and mixtures of liquids, solid proportion is sunken to lower floor greater than liquid, and liquid level is higher than solid level, and this detection instrument can once be measured the liquid level of the material level and the liquid of solid simultaneously.In addition, this detection instrument has used single chip microcomputer, and any a plurality of material level alarm set point can be set, and can realize long-range digital remote control, remote measurement, can also network with upper PC.
Of the present utility model finishing is achieved in that on the pillar top of a removable mounting in support and fixes a pulley, the lower reaction of pillar is on pressure transducer, rope that connect to measure weight is walked around above-mentioned pulley and another friction pulley hub disk on cylinder, makes pressure transducer reflect pulling force size on the rope.The axle pulse encoder that is installed on the friction pulley can be measured weight displacement.Weight is placed in the warehouse of liquid level to be measured and material level, is rotated by the driven by motor cylinder, and makes moving of carrying or transfer on the weight work by rope.The voltage signal of pressure transducer output send 8098 single chip microcomputers after amplification, filtering, the pulse signal of axle pulse encoder output also send 8098 single chip microcomputers behind the pulse shaping circuit, after single chip microcomputer is handled, is analyzed the signal that receives, judge whether weight has touched liquid level or material level, the umber of pulse of also passing through to be write down simultaneously can accurately calculate the residing position of weight.
Detection instrument described in the utility model can directly show the height of tested liquid level and material level, and by the rotation of controlled by single chip microprocessor motor, thereby can Continuous Tracking measure, realized automatic monitoring to the tested material height.In addition, the use of single chip microcomputer, pressure transducer and axle pulse encoder improves measuring accuracy and measurement performance again greatly.
Below in conjunction with accompanying drawing the utility model is described in detail, wherein:
