Diaphragm seals for stable flow measurement in deep seas
Jing Lyu | ApplicationsDiaphragm seals make it possible to adapt measuring instruments to even the most extreme conditions. One example is the deep-sea extraction of oil and natural gas. For offshore companies in this industry, a particular OEM company manufactures flow measuring systems …
Pressure and temperature measurement at extremely low ambient temperatures
Christopher Ott | Know-howStandard pressure gauges and thermometers generally cope with ambient temperatures down to -40 °C. But what must be the features of a mechanical measuring instrument that works perfectly well in polar climates with even lower temperatures? This can be explained using …
Check friction clutches using the chain hoist test set
Markus Heidl | ForceChain hoists are used for lifting and lowering freely moving loads. As a lifting device, the chain hoist supports, for example, ergonomic lifting during assembly work or even makes this possible in the first place. Conveyor technology or crane systems are further …
Difference between gauge pressure and absolute pressure measurement
Michèle Beyer | Know-howAgain and again, we are asked the question about the difference between an absolute pressure measurement and a gauge pressure measurement. To answer this question it helps to look at the definition of gauge pressure and absolute pressure. The difference between the two …
