Poznámky k přesnému vyvážení

Poznámky k přesnému vyvážení Jak všichni víme, přesná váha je druh přesného elektronického nástroje, which is widely used in laboratory and medical fields.This electronic balance uses a higher precision sensor and more control chip, so it has higher precision and sensitivity than ordinary electronic balance.Although the precision balance has many advantages, it is easy to be interfered by external factors, electromagnetic and other factors, which will produce certain errors. So how can we improve the accuracy...

Stanovení vzduchové propustnosti papíru

Fundamentals The pressure difference method is used to place the pre-processed sample between the upper and lower measuring surfaces, a na obou stranách vzorku se vytvoří konstantní tlakový rozdíl.Působením tlakového rozdílu, plyn proudí z vysokotlaké strany přes vzorek na nízkotlakou stranu, a propustnost vzorku se vypočítá podle plochy, tlakový rozdíl a průtok vzorkem. Definition of breathability Average air flow through paper...

Drsnoměry lze spárovat s několika snímači

Drsnoměry lze spárovat s několika snímači Když měříme různé obrobky, we will match different sensors for measurement.So how many sensors can roughness gauge be matched with?How many sensors are there?The following Xiaobian to answer Sensors are divided into: 1. Standard sensors Standard sensors use the most sensors, it can measure most of the plane, inclined plane, conical surface, vnitřní otvor, groove and other surface roughness, can be carried out hand-held measurement, in addition to the standard sensor, other sensors need...

What are the factors that affect the measurement accuracy of coating thickness gauge

Description of factors affecting measuring accuracy of coating thickness gauge A) Magnetic properties of the base metal Thickness measurement by magnetic method is affected by the change of the magnetic properties of the base metal (in practical application, the change of the magnetic properties of the low carbon steel can be considered to be slight). In order to avoid the influence of heat treatment and cold working factors, the standard sheet with the same properties as the sample base metal should...

Pochopit princip a použití přístroje pro měření drsnosti povrchu

Nástroj drsnosti se také nazývá nástroj drsnosti povrchu, nástroj pro povrchovou úpravu, detektor drsnosti povrchu, přístroj na měření drsnosti, měřič drsnosti, roughness tester and other names. It was first developed and produced abroad and then introduced into China. Roughness meter measuring the surface roughness of workpieces, put the sensors on the workpiece surface to be tested, by instrument internal drive mechanism drive the sensor do constant speed glide along the surface to be tested, sharp sensor through the built-in stylus feel the...

Je nutné pochopit technický princip tloušťkoměru povlaku

Princip měření magnetického sání Velikost sání mezi magnetem (sonda) and the magnetic steel is proportional to the distance between the two, which is the thickness of the coating.Using this principle to make a thickness gauge, as long as the difference between the magnetic conductivity of the coating and the substrate is large enough, it can be measured.Since most industrial products are made of structural steel and hot and cold rolled steel sheets, magnetic thickness gauges are...
