Abstract
ICP® technology is an integral part of electronic measuring technology combined with sensors. We find this two-wire technology in laboratories, test benches, in production, in monitoring systems and mobile test installations. Even if it is a simple and proven technique, you should pay attention to some parameters in the sensor selection. New developments provide additional protection against unwanted overloading and also offer higher temperature stability, which improves the values of the measurement uncertainty by a factor of 10.
In the lecture the problem of overloading will be discussed. With examples from practice regarding the reasons for a overloading, detection and prevention. Various application examples are shown. The use of newer generation piezoelectric materials such as the UHT-12 ™ industrial single crystal significantly improves the measurement uncertainty and quality of the measurement signals. The technical characteristics of this material are explained and the advantages of using it as a measuring element are shown.
