From optional to standard: the most important is to measure

Does the name Josip Belušić, in Italian Giuseppe Bellussich, mean anything to you?
And if the second question was: what is the “velocimeter”?
Definitely we should give you a suggestion, or let you the time to look on the internet to find out the Croatian family name Belušić, and discover that it is about the inventor of the tachometer.


Also known as “odometer” or “milometer”, it was invented and patented in 1888, and presented the following year at the Wold’s Fair in Paris.

130 years after its invention, nowadays the tachometer is compulsorily fitted on all motor vehicles, but it’s funny to believe that initially it was only available as an option, as it became standard equipment only after 1910. – Designed by welcomia / Freepik

An example, a question, a provocation

This short historical excursus made us smile, because we often make this example to our customers: Try to cover the tachometer of your car, and to drive with your subjective speed perceptions. Are you really sure to be able to perceive the constancy of the speed with your sense only? And mostly important, would you be able to keep all the way long your drive within the applicable speed limits?

Someone replies to have already driven on a highway at 180 Km/h without realizing it, until a squad car stopped him. But definitely it has happened to the majority to drive around the town with the intention to comply with the speed limit allowed, and to have got the impression to drive at an exasperatingly slow traveling.

Our merely provocative question is useful to approach the subject of the measurement in the textile field, in order to carry our interlocutor to the obvious: it is not possible to measure depending on the perception, as its error margin is really high!


Better quality and lower costs

Several of our devices have really shown that the perception is not sufficient! Even where there was the experience of an operator or of a handler, the installation of ETV systems has brought substantial benefits to the company. With more precise and constant measurements of moisture and temperature, it is possible to achieve better quality and lower costs in the textile manufacturing processes.
