Background technology
In production is machined, generally require to carry out being precisely controlled for position, and in technology today, in order to be able to realize energy
The displacement of object is measured, usually using following several method：
A) slide potentiometer mode：With the slidingtype adjustable potentiometer of length-specific, slide son and be fixed on tested mover；
Potentiometer two ends connect power supply, and positional value is worth to by measuring voltage.
B) inductance type slides measuring appliance mode：By the coil of special coiling, there is a magnetic conductance on the sliding axle in coil
Body, slides son and is fixed on tested mover；By excitation coil, the diverse location for sliding son produces different undesirable mutual electromagnetic inductance amounts,
So as to measure positional value.(industrial slip measuring appliance)

A) slide potentiometer mode, key is contact abrasion, is not durable.Next to that the slip of indivedual routines can only have been bought
Potentiometer, remaining length requirement is required for customized, then producer is few, is had any problem in the guarantee of quality.Less demanding situation
Under, can make in this way.
B) inductance type slides measuring appliance mode：The volume that coil is accounted for is big, while making and circuit design difficulty.Can produce simultaneously
Raw Electromagnetic Interference.This mode volume is big, is only suitable for large scale equipment, while to install the measure of multiple anti-electromagnetic wave interference.
C) gear impulsive measurement mode：Key is can only to measure relative distance, it is desirable to starting point is relocated, under some environment of position
Be inconvenient to reposition starting point and do not apply to then, in addition because needing uninterrupted measurement, while the unpredictability of motion, if surveying
Amount operation part design is improper, or movement velocity exceedes code measuring speed, and some electric pulses can not detected, then accumulated result
Can malfunction.It is because some machine arithmetic parts also take on other processor active tasks simultaneously, then organic to occur that arithmetic speed is low, from
And miss the detection of some pulses.
D) ultrasonic wave mode：This is only applicable to out environment wide, and multiple echo can be produced on machine, while distance range
Too small, ET is short, indeterminacy.
