Solutions for Pharmaceutical Industries

History

Since 1964

Anritsu's inspection systems started with innovation of signal processing.

Anritsu's first Checkweigher was purchased by pharmaceutical company

Anritsu's checkweighers have advanced together with the pharmaceutical industry.

We delivered our first checkweigher to a pharmaceutical manufacturer. Learning from the pharmaceutical industry’s rigorous attitude toward quality control, Anritsu Infivis has since continued to develop its technologies. Anritsu Infivis is committed to addressing advanced quality assurance issues through closer cooperation with customers and partners in the pharmaceutical industry.


1964

Not so long after desktop electronic calculators were put out into the world, Anritsu gave birth to its checkweigher, which was based on electronic micrometers that electrically measure micron-level displacement using a differential transformer. And that was an innovation. By measuring the difference of weight based on displacement of a coil, we developed a weighcell by ourselves to be built into a machine which is able to reject products - our first checkweigher K501A.

1895

In 1895, Anritsu's predecessor Sekisan-sha was founded. The company improved its performance particularly with the production of Morse printers. With a merger in 1908, the company became Kyoritsu Electric Wire, and expanded its operations with the production of public telephones that had just been launched in Japan.

Around that time, technologies connected to the current business of the Anritsu Group were discovered; Guglielmo Marconi in Italy succeeded in wireless telegraphy based on radio waves, and Wilhelm Conrad Röntgen in Germany discovered X-rays and succeeded in taking radiograph. Anritsu has a history of advancing together with technologies for signal processing, particularly communications.

We disclose six facts in the history of Anritsu for more than half a century.

Topic 1: Cumulative shipments of checkweigher

Cumulative shipments of checkweigher

Over 80,000 units

Ever since we shipped our first checkweigher K501A that was put on sale in 1965, we have sold more than 80,000 units of checkweighers in total.

We have also sold more than 50,000 units of metal detectors and more than 10,000 units of X-ray inspection systems.

Topic 2: Countries of destination

Countries of destination

Over 50 countries

Our products are used by customers not only in Japan but also in many countries, from major pharmaceutical manufacturers in the U.S.A., Germany, Italy, China and India, to emerging countries such as Vietnam, Indonesia and Argentina.

Topic 3: Capsule Checkweigher

Capsule Checkweigher

Since 1970

Ever since its early years, Anritsu has developed weight inspection equipment for minute weight products. The K515, capsule checkweigher developed in 1970 featuring five small parallel spring microbalances and Anritsu’s proprietary capsule feeding design, had the capacity to weigh 600 capsules per minute at an accuracy of 2 mg.


Topic 4: Electromagnetic force balance weighcell

Electromagnetic force balance weighcell

Since 1989

Achieved the world's top-level speed of 400 products/minute and accuracy of ±0.02 g not by weighing based on gravity but by balancing against electromagnetic force generated by a coil.


Topic 5: World’s first automatic sensitivity setting for metal detectors

World’s first automatic sensitivity setting for metal detectors

Since 1991

Nowadays, most metal detectors are with the function of automatic sensitivity setting, but Anritsu’s KD801Ax released in 1991 was the world’s first one with the function. With its expertise acquired in the field and total engineering capability in terms of both hardware and software, Anritsu automated phase adjustment that used to be dependent on skilled engineers’ intuition and experience.


Topic 6: In-house development of X-ray inspection system

In-house development of X-ray inspection system

Since 2000

The KD7203AW is a high-sensitive contaminant detector that generates stable X-rays with an inverter power source and proprietary X-ray tube and uses image processing algorithm developed in-house. Launch of this small-sized X-ray inspection system at an almost half price of conventional large-sized, high-priced models facilitated the widespread use of X-ray inspection systems.
