Notes : Performance data are given for steady phase of the transducer.

Transitory period after power on lasts typically less than 2 min.

Please refer to characterization report for details.

Please don't put the high voltage between the secondary pins and fixing

pins. If it must be so, don't exceed the 2.5 kV between these pins with the

maximum isolation distance.
