Description
Technical field
The present invention relates to the sensors of gauge table.
Background technique
There are following scarce limits, mainly light for a kind of non-contact direct reading type gauging table (number of patent application 2005200547306)
For electric device with using the time long, parameter change causes reading to malfunction.Occurs meter reading error after many half a year.Direct-reading intelligence
The gauge tables such as ammeter, intellectual water meter and intelligent gasometer determine pointer or the character wheel turned position of gauge table with electronic component.Such as
0 to 90 numbers on character wheel are indicated with ten different gray scales.It is most black to indicate 9, most white expression 0.When 9 are transitioned into 0, photosensitive tube
Incude most black and most white average value, it is possible to the influence value as 5 occur.The intellectual water meter now used, needle pivot and water
Rachis is connected with magnet.There is a plastic plate among two axis, by electronic section and water segregation.The circle number for be easy to causeing waterleaf to rotate
Greater than needle pivot, cause intellectual water meter metering inaccurate.The pointer or word of pulse intelligent ammeter, intellectual water meter and intelligent gasometer
One circle of wheel rotation, add up a pulse.Pointer or the character wheel turned position for only judge lowest order (such as an a position), do not judge ten,
Hundred, the high-order pointer or character wheel turned position such as kilobit.Ten, hundred, the data of kilobit lean on the pulse data of a position cumulative.
Such as without electricity, cumulative pulse data can be lost.It to be powered for a long time, the pointer of (a position) or character wheel turnning circle be not when out of power
It can be cumulative.The umber of pulse of loss out of power cannot be restored after powered up.
