BISOPE series 48- Acceleration sensor - ICP, IEPE (internal amplification circuit)

-------------------------------------------------------------------------------------------------------------

The amount of charge generated from the transducer (sensor; converter) must express minute differences, so careful attention is required on the measurement path. In particular, noise from cables or noise caused by installation errors can lead to fatal measurement errors. Modern measurement methods are more compact, more accurate, and often include self-calibration. In particular, the external amplifier (Charger type) system used in the past must amplify and use the amount of electricity by using an amplifier in the middle in order to show a large amount of small charge.

ICP Accelometer(Integrated circuit Piezoelectric type=IEPE)

 

When pressure is applied, electricity is generated... The amount of charge generated by the 'piezoelectric effect' is very small, and as you can imagine, it is not enough to perform the 'generating function' that electricity will be generated when vibration is applied to the element. Th

BISOPE series 33- Simple vibration diagnosis and precision vibration diagnosis of rotating machinery

--------------------------------------------------------------------------------------------------------------------------------------

The results of the vibration diagnosis can be confirmed as a technical report, which is largely divided into a simple diagnosis report and a detailed diagnosis report, etc., and is prepared including the cause and evaluation of the current vibration problem, and a description of countermeasures if necessary. The meaning of each report is a simple report in the case of simple evaluation of phenomena and absolute standards after temporary measurement, and detailed analysis to the extent that current causes can be analyzed and countermeasures can be found through spectrum analysis and cause analysis of various vibrations. are treated as detailed reports. In general, the definition of regular textbooks for facility diagnosis qualifications is not very different.

 

Simple diagnosis and precise diagnosis, offline and online

First of all, if you look at the methods of simple diagnosis, there are 'route measurement' and 'online monitoring system'. Inspection is commonly referred to as 'off-line' as a method in which humans intermittently investigate and record the state of equipment using a portable instrument (vibration meter, data collector). On the other hand, constant monitoring is a method of continuously monitoring by a monitoring device and is called 'on-line'. Inspection called off-line can measure many measurement points and directions, but it cannot be said to be continuous depending on the frequency of measurement. There are advantages and disadvantages between the two systems, since on-line continuously monitors and stores near real-time data from already installed sensors.
