Abstract
The utility model relates to a metering sensor for detecting the movement of a gauge pointer, which comprises a reed switch tube arranged in an aluminium shell, a resistor connected with the reed switch tube in parallel and a permanent magnet fixed on one end of the reed switch tube, wherein conducting wires on both ends of the reed switch tube are led out of the aluminium shell, the other permanent magnet is arranged on a pointer of a metering gauge, and a reed of the reed switch tube keeps a certain distance away from the permanent magnet; when the pointer rotates 360 DEG, a reed switch is attracted or disconnected once. The utility model can be connected with a counter or a data acquiring device to obtain the accumulated reading of the gauge or is connected with a microcomputer to realize the centralized management of the metering gauge, and is applied to all metering gauges driven by rotary machinery.
Description
The utility model relates to a kind of sensor, particularly the gage probe of rotary indicator formula instrument.
At present, measuring instruments such as widely used tap water, coal gas and electric power, all disperse to be installed in user's dwelling, regularly go to the numerical quantity of using of copying water meter, ammeter and the gas meter of getting each user by special meter reading personnel, this traditional operation all brings a lot of inconvenience for user and administrative authority.Because the appearance of high-rise apartment building and residential quarter, it is more concentrated to live, and to the centralized management of tap water, coal gas and electric-power metering, improves the estate management level of residential block, is a problem that urgency is to be solved.
It is a kind of on traditional rotary indicator formula measuring instrument basis that the purpose of this utility model is to provide, and its metering numerical value become the detection instrument list index motion gage probe of electric signal transmission.
The key that realizes the utility model above-mentioned purpose is: a permanent magnet is housed on traditional instrument rotary indicator, it is rotated with pointer, an inside is set above magnet the reed switch pipe of two reeds, described tongue major axis is parallel with the magnetic pole Plane of rotation of the permanent magnet of rotary indicator, and maintains a certain distance; Described reed switch pipe two ends also are connected with a fixed resistance that constitutes the self check branch road, and when reed switch disconnected, sensor loop was in the normally closed self check state of low-power consumption, and resistance branch is by short circuit when the reed switch closure, and sensor is in the transmission signal condition; Described fixed resistance is positioned at reed switch pipe top, and other has a stationary permanent magnet to place an end of reed switch pipe, and its pole orientation is consistent with reed switch sheet long axis direction; Described reed switch pipe, fixed resistance and stationary permanent magnet all are packaged in the rectangle alloy aluminum hull by above-mentioned position, but filling waterproof insulation filling material in the alloy aluminum hull, and two leads that are connected with the reed capsule two ends are drawn in alloy aluminum one end perforate; When described gauge pointer drove 360 ° of rotations of permanent magnet do, pole orientation was also rotated, when rotary pole is identical with the fixed magnetic pole direction, described two reed adhesives, when both were reverse, the demagnetization of two reeds disengaged, rotary magnet is done 360 ° of rotations, and two tongue adhesives disconnect once.
Two extension lines of the present utility model can be connected with counter or data acquisition unit, and the folding number of times of record reed just can obtain the accumulative total reading, and is online with microcomputer, can carry out data processing, realizes the centralized management of metering.
The utility model can convert the hand motion number of turns of conventional metered dose instrument to reed opening and closing number of times and note, and can realize online with computing machine reaching the centralized management purpose to measuring instruments such as cluster water meter, ammeter and gas meters.Of the present utility model rational in infrastructure, when mounted, need not destroy former measuring instrument structure, only need the reed switch pipe is placed on the apparatus glass face, the magnetic field between magnet just is enough to guarantee the reliable adhesive performance of tongue.Because this device is provided with wireline inspection resistance, so during with microcomputer network, have the function that system tests oneself.
Accompanying drawing is a cut-open view of the present utility model.
Concrete structure of the present utility model is referring to accompanying drawing: rectangular parallelepiped permanent magnet 7 is contained on the rotatable pointer of instrument, and pole orientation is a major axis, and rotates with needle pivot 8; In the reed switch pipe 1 two reeds 2; Fixed resistance 4 is connected in parallel with the two ends of reed switch pipe 1, stationary permanent magnet 3 is placed on reed switch one end, its pole orientation is consistent with the reed switch long axis direction, above-mentioned reed switch pipe 1, fixed magnets 3 and resistance 4 are encapsulated in the alloy aluminum hull 5, and fill with the waterproof insulation stuff, described reed switch pipe 1 two ends lead 6 is drawn by aluminum hull 5 one end perforates.
Rotation permanent magnet 7 rotates with needle pivot 8, reed switch pipe 1 is placed in the pole orientation Plane of rotation scope, and maintenance certain distance, reed switch 1 major axis is parallel with Plane of rotation, when the magnetic pole N of rotary magnet 7 to the magnetic pole N of stationary permanent magnet when consistent, reed switch pipe 1 is in strengthens in the magnetic field intensity, reed 2 is magnetized and is two opposite poles and adhesive; When rotation permanent magnet 7 goes to when making magnet 7 and 3 liang of pole orientation of stationary permanent magnet be the upright position, reed 2 still keeps former attracting state; When magnet 7 rotates 90 ° again, make two pole orientation reverse, at this moment, reed switch 1 is in weakens in the magnetic field intensity, reed 2 is two like poles by demagnetization and repels and leave, when magnet 7 rotates 180 ° again, two magnets are in pole orientation position in the same way once more, and the adhesive once more of reed switch sheet is so pointer magnet carrier 7 revolutions move 360 °, make the reed switch adhesive once, reach the requirement of instrument record with this.
Gap dielectric between reed switch 1 and the rotary magnet 7 is any unmagnetized material, as: air, water, oil, glass, aluminium, copper etc.
Principle of work of the present utility model as long as have the indicating mechanism of rotation, and can drive that permanent magnet rotates in all multi-form instrument, all can use the utility model as sensor.
