Description
Technical field
A kind of current vortex sensor Installation and Debugging of the utility model device, relates to installation of sensors debugging field.
Background technology
Current vortex sensor is a kind of displacement transducer, and it is highly sensitive, and the range of linearity is large, wide frequency range (DC~10KHz), and physical dimension is little, and antijamming capability is subject to by force and not medium influence etc.The accuracy that current vortex sensor need to vertically face the circular flat of its sensor front end the surface of object being measured and keep certain measuring distance guarantee to measure.It and testee are contactless, are therefore specially adapted to the vibration monitoring of rotating machinery, the measurement of axial translation and orbit of shaft center.When current vortex sensor is applied in the main shaft runout measurement of hydrogenerator, need to be fixed with a support, and guarantee that sensor and unit under test maintain a certain distance, this distance will meet transducer range scope, this distance whether suitable, directly determine the accuracy of sensor measurement, the accuracy of therefore adjusting this distance and adjustment is particularly important.
Existing current vortex sensor and unit under test apart from the method for adjusting be by testing apparatus (signals collecting case) connect as external power supply ± 24V to sensor, power, according to the distance of test result determine sensor and unit under test, whether meet the demands and adjust in real time, shortcoming is to need multiple person cooperational (at least needing 3 people): a people is at testing apparatus place, observation test computer upper sensor output voltage signal value, this magnitude of voltage is told to the staff of field adjustable sensor by intercom, one people assists, another people utilizes leatherhead, and (adjustadle wrench is adjusted the nut of sensor and then is completed and adjusts sensor and measured object distance, because the position of sensor installation is sometimes narrow, one people has and cannot complete, many people space is inadequate again, debugging work is very difficulty, generally to repeatedly link up, adjust, waste time and energy.Because many people participate in debugging, degree of tightness, the sensor correspondence direction of the sensor nut of everyone debugging can be different, and these factors all can cause measurement data to have error, are unfavorable for the analytical work of test.
Adopt clearance gauge to measure mounting distance, shortcoming is at installation of sensors position, need many people to coordinate: a people utilizes clearance gauge to adjust mounting distance, another people utilizes leatherhead, and (adjustadle wrench is adjusted the nut of sensor and then is completed and adjusts sensor and measured object distance, and because the position of sensor installation is sometimes narrow, a people has and cannot complete, many people space is inadequate again, debugging work is very difficulty, generally will repeatedly link up, adjust, and wastes time and energy.Because clearance gauge measurement exists personal error, and the sensitivity of sensor is very high, and measurement range is very narrow again, generally at (0 ~ 2mm), this error has a great impact the measurement result of sensor, and these factors all can cause measurement data to have error, is unfavorable for the analytical work of test.
Current vortex sensor in the process of one-shot measurement, the installation site to sensor, the distance between the installation direction of sensor and sensor and unit under test has requirement, can not arbitrarily change.This distance will meet transducer range scope, and this distance whether suitable directly determine the accuracy of sensor measurement, so whether the distance on sensor and testee surface is accurately particularly important.
Summary of the invention
The utility model provides a kind of current vortex sensor Installation and Debugging device, in installation of sensors process, uses this Installation and Debugging device, and a people can complete speed governing work fast.Greatly reduce manpower, shortened the set-up time, improved installation accuracy.
The technical scheme that the utility model is taked is: a kind of current vortex sensor Installation and Debugging device, comprise portable power source, and portable power source connects voltage measuring apparatus and current vortex sensor, and the output terminal of current vortex sensor connects voltage measuring apparatus.
Described portable power source is that the Ni-MH battery of three joint 9V is in series.
Described voltage measuring apparatus is multimeter or digital display DC voltage table.
A kind of current vortex sensor Installation and Debugging of the utility model device, when installing at the scene, can adjust faster electric whirlpool installation of sensors position and and unit under test between distance, guarantee the precision of electric whirlpool sensor measurement.Short time can be adjusted a plurality of current vortex sensors, because the time interval is short, can guarantee that the distance of adjusting has high unity, realizes Data Comparison.
Accompanying drawing explanation
Fig. 1 is a kind of current vortex sensor Installation and Debugging of the utility model device connection diagram.
Embodiment
A current vortex sensor Installation and Debugging device, comprises portable power source, and portable power source connects voltage measuring apparatus and current vortex sensor, and the output terminal of current vortex sensor connects voltage measuring apparatus.
Adopt the Ni-MH batteries series connection of three joint 9V as the portable power source of current vortex sensor, its voltage is: 27V, meets the service area of current vortex sensor).The both positive and negative polarity "+" " ﹣ " of portable power source is connected with current vortex sensor with voltage measuring apparatus by connecting wire, the output terminal of current vortex sensor is connected with voltage measuring apparatus by connecting line again, and all metal connecting portions all will be tied up with insulating tape.Described voltage measuring apparatus is multimeter or digital display DC voltage table, and the utility model preferentially adopts two-line digital digital display DC voltage table.
The voltage that digital display DC voltage table shows, is directly proportional to the distance on current vortex sensor and testee surface.Transducer range is at 0 ~ 2mm, supply voltage+24V, and defining relation is as follows: when digital display voltmeter shows 18V, corresponding distance is+1mm, when digital display voltmeter demonstration+2V is that corresponding distance is-1mm.In debug process, when be shown as+10V of digital display voltmeter, corresponding distance is the central point of the sensor measurement range of linearity, by this magnitude of voltage, can know in real time the distance between current vortex sensor and testee surface, and this distance is exactly that test needs the distance of adjusting.In installation process, adjust the distance on current vortex sensor and testee surface until meet the demands, then fastening sensor nut, completes the installation of sensor.
