First, principle

The non- contact type electricity turbulent flow position transmitter, is "the turbulent flow effect" becomes based on the high frequency magnetic field in the metal surface, is to the gold
Is the object the displacement, the vibration, the rotational speed and so on the mechanical quantity carries on the examination and the control ideal sensor. It has the non- contact survey, the line
The natural scope width, the sensitivity high, the antijamming ability strong, the non- medium influence, stable reliable, is easy to process and so on the obvious merit, widespread
Uses in profession and so on in metallurgy, chemical industry, astronautics, also may use in the scientific research and the school experiment displacement, the vibration, the rotational speed, the length,
Thickness, surface irregularity and so on mechanical quantity examination.
At present the our company produces the electricity turbulent flow type sensor has two big kinds: Displacement, oscillationpick-up and tachometer generator.

Fifth, the position transmitter connection and demarcates

1st, sensor and pretage converter connection
(1)th, through the high frequency electric cable connection, the standard length is 3 meters.
(2)th, the biggest coca solstice 9 meters, must order when explained.
2nd, sensor and pretage converter demarcating
(1)th, environment: Room temperature 20±5 �?br> (2)th, material: 45□| the steel (user may assign to measure material)
(3)th, equipment: Static demarcating 0-25mm±0.005
(User may select and match this company static demarcating voluntarily to demarcate.)
(4)th, static demarcating:
Static demarcating is has custom-made by the high accuracy micrometer and the special-purpose support becomes, uses in the sensor static state to demarcate with the calibration, the sensor input ¨d¨d input level curve, simultaneously uses for to obtain in order to ideally installs is away from and demarcates the converter standard output. The passable regulating nut has adjusted the sensor with to measure the body the relative distance, carries on the displacement with the micrometer the static state to demarcate or the calibration.
(5)th, demarcates the method
Sets at the sensor on the static demarcating cartridge, places the test sample on the test sample support, the test sample must act according to actual was measured the body the material and the shape choose, the pretage converter four cores attachment and the power source and the digital multitester correct connection, turns on the power source, causes the pretage converter normal work. The change static state demarcating regulating nut causes the sensor and the test sample slightly contacts, the adjustment "fullness" the potentiometer to a smaller position, acts according to linear scope section under again which each sensor in the input level table provides 限点, adjusts the micrometer, changes the sensor and the test sample distance, then, the adjustment "the zero position" the potentiometer, causes the converter the under 限点 output reading is "0V", (for example is ±5V output, then moves for ¨d5v) changes the micrometer again, to the linear section on 限点 adjustment "fullness" the potentiometer, causes the converter on 限点 output reading is "5V". Changes the micrometer to the linear section center point, the examination output reading whether is "2.5V" (or is 0V). If is just right, then indicated the sensor basically adjusted. If the discovery center point voltage reading is bigger than "2.5V" (or is smaller than "2.5V"), but regarding ±5V loses the origin to have to look whether is bigger than 0V (or is smaller than 0V), then under 限点 the position approaches to the test sample (or leaves far). Then the repetition above method, continues to adjust. Until under 限点 delta 1, the center point delta 0 and on 限点 delta 2 these three point correspondences output readings become the straight striation, conforms to the precision up to. After once adjusts, it "the zero position" and "fullness" the potentiometer not suitable again has moved, guarantees the precision measuring. "The zero position" and "fullness" the potentiometer is must repeatedly adjust several times, can achieve the optimum condition.

Sixth, sensor installment

After determined the sensor already demarcated completes. Dismounts the sensor, together with the avonmeter and the power source same place, installs actual was measured
Body place. Adjusts the sensor with to measure between the body the distance, causes the converter the output reading to conform to the examination requirement.
Generally speaking, (take "0¨D5V" output as example) measures the vibration, should cause the output instruction is "2.5V" is the linear section center point. Measures the displacement, if were measured the body the displacement is bidirectional also should cause the output instruction is "2.5V" is the linear section center point. If is unidirectional, should cause the output instruction is "0V", or "5V" Namely linear section lower limit or upper limit. After installs unmistakably, fixed sensor then.
The tachometer generator installment quite is simple, so long as aims at the sensor front end surface is measured the revolution axis the sampling hole or the sampling tooth
The wheel, the maintenance has 2 ~ 3mm the gap, fixed sensor then.

Seventh, application
1st, uses in the metal material quality examination, for example:
(1)th, migration, position, displacement, inflation, size
(2)th, vibration, displacement, gap, resonance
(3)th, the bearing vibrates, the lubrication gap, the attrition, the displacement
(4)th, commutator out of roundness, roundness, the air gap, divide
(5)th, compressor, turbine gap, rotational speed
(6)th, impact, distortion, axial axis vibration
2nd, uses in the mechanical revolution axis tachometric survey and the monitoring

Eighth, matters needing attention

1st, the connection is unmistakable, after puts through the power source, please preheating 10 minutes.
Periphery 2nd, pokes head in a time to poke head in the diameter place, cannot have other metal materials.
When 3rd , work, should avoid the strong magnetic field and the strong electric field disturbance.
When 4th , between the sensor and the pretage converter plug, the plug work, should not have the vibration, in order to avoid causes the output change.
5th, the high frequency electric cable length cannot fluctuate at will.
6th, makes up the sensor without the temperature which enjoys, the survey environment cannot appear the temperature rapid change, increases the measuring accuracy.
7th, in use, if has the question, but is direct and the factory relation.

(Company has in addition with sensor, pretage converter necessary two measuring appliances, special-purpose power source has many kinds of specifications, welcome to deign to inquire, welcome to select and purchase.)
