Failure causes and sources of errors in sensors: Mechanical failure – defected cables, lines or connectors

Cable break / lead breakage, broken connectors and damaged cable insulation – many of these failure causes and sources of errors in sensors can be traced back to mechanical failure of qualitatively inferior components.You have carefully selected a supplier for high-quality pressure transmitters / pressure sensors and made sure these pressure transmitters meet the requirements … Read more

Vibration protection: Case filling vs. dampened movement

Vibrations can sometimes violently load Bourdon tube pressure gauges. They cause pointer flutter and in addition, in case of sustained loading, damage to the measuring system, even to the stage of total failure. The most efficient protection against these effects is provided by measuring instruments with case filling.The principle is easy: The pressure gauge case … Read more

Dual range pistons for pressure calibration

Dual piston deadweight testers can greatly enhance a lab?s ability to calibrate wide pressure ranges with the highest accuracy. With transducers and devices under test (DUTs) which have a broad measuring range, calibration can be quite a lengthy process, as you must change pistons in between test points so that you can calibrate its entire … Read more

How do diaphragm seals work?

Diaphragm seals, also known as chemical seals or remote seals, are used for pressure measurements when the process medium should not come into contact with the pressurised parts of the measuring instrument. Withheld has two primary tasks:1. Separation of the measuring instrument from the process medium2. Transfer of the pressure to the measuring instrumentOperation of … Read more
