Precision 300 kHz Ultrasonic Transducer

(For double feed detection)

PiezoData Inc. offers high quality 300 kHz ultrasonic transducer. It is one of our high-frequency ultrasonic sensors. The 300 kHz ultrasonic transducer is designed for sensing multi-feeding of blank sheets in a scanner, printer, and ATM.

In many instances doubles have a positive connotation. But in sheet feed printing and stamping process, doubles are definitely viewed as a negative connotation.

In an office environment, there are instances you can encounter a paper jam, forcing you to open up a copy machine to check the roller if there are two sheets of papers. This gives you an idea of what can happen to a print process.

The jam ups can be catastrophic when printing books or magazines. The 300 kHz ultrasonic transducer can definitely help in keeping downtime, subsequent maintenance and damage to an absolute minimum.

Printing books, magazines or newspapers is a complex process that requires specialized high-end electronic controls and huge paper feeding. During this process, a single blank sheet of paper can ruin a work of 100,000 or more copies because it made its way through to the middle of the books or magazines. In order to maintain efficiency and high speed in any smooth printing, you need a 300 kHz ultrasonic transducer to prevent the possibility of a double feed of papers.

PiezoData Inc. 300 kHz ultrasonic transducer is specially designed for the applications of misfeed detection, label counting, and splice detection.

PiezoData Inc. high quality 300 kHz ultrasonic transducer can detect very thin papers less than 40grams weight, medium size papers like those of copier machines and double sheet situations like thick credit card type materials.

The 300 kHz ultrasonic transducer can also detect the thin metal sheet. You can also find 300 kHz ultrasonic transducer applied in ATM to detect currencies, voting scanners, and so on.

300 kHz Ultrasonic Transducer: The Complete Guide by Method and Principle

300 kHz Ultrasonic Transducer -Principle of Operation

Now let’s talk about how a 300 kHz ultrasonic transducer (ultrasonic double sheet detector) operates.

This is how sonic double sheet detector operates.

Ultrasonic double sheet detector systems have dedicated 300 kHz ultrasonic transducer emitted and a dedicated 300 kHz ultrasonic transducer receiver.

The 300 kHz ultrasonic transducer emitter constantly sends an ultrasonic signal to the 300 kHz ultrasonic transducer receiver unit.

The receiver detects and then bases its output upon the strength of the signal it gets back from the emitter.

If the 300 kHz ultrasonic transducer receives what it detects to be a full signal strength level and a full amplitude level, it interprets it to be no sheet present.

And on the back side of the 300 kHz ultrasonic transducer (sensor), there are series of LEDoutputs that relay the no sheet present signal.

As a single sheet comes into play, the single sheet will cut approximately 80% of the sound from the emitter to the receiver.

Again in the receiver unit, there is a threshold, and it detects when the sheet cuts 80% of the sound time and relays the same information for single sheet output through the LED.

If you have a double sheet, the double sheet will cut another 16% of the sound away. So you will have 4% percent of the sound remaining. The receiver unit knows that you have 4% of the sound remaining, and interprets it as a double sheet condition.

Your output and LED fires, then there is no way to detect sheet beyond a double sheet. So if you have tripled, quadruple it will be signaled as a double sheet as well.

300 kHz Ultrasonic Transducer – How Important is Double Sheet Detection?

In many instances doubles have a positive connotation like youngsters who get a scoop of ice cream at a local ice cream shop or perhaps batter who takes a high bell fastball and rips it into right field for a double.

On the other hand, doubles have a negative connotation as a person rolling dice, hits snake eyes at the game table or a golfer perhaps misses his putt and gets a double bogey.

In sheet feed printing and stamping process doubles are definitely viewed as negative if you’ve ever been in an office environment and a paper jam occurs, then you open up a copy machine and look in the rollers and see two sheets of papers.

It gives you an idea of what can happen to a print process when a double occurs. Maybe you can get a bigger idea if you expand that out and when somebody is making instead of just a copy of a single sheet, a magazine, newspaper or something like that.

Those jam ups can be catastrophic. A 300 kHz ultrasonic transducer is the perfect helper for keeping downtime, subsequent maintenance and damage to an absolute minimum. The 300 kHz ultrasonic transducer is designed to instantly identify double sheet occurrences before the problems get too far downstream.

Think about this, how would you react if ATM gives you wrong banknotes?

Definitely, you will get mad.
