scope:

This Standard applies to transducers with electrical inputs and outputs for making measurements of a.c. electrical quantities. The output may be in the form of an analogue direct current or in digital form. In this instance, that part of the transducer utilized for communication purposes will need to be compatible with the external system. Within the measuring range, the output signal is a function of the measurand. An auxiliary supply may be needed. This standard applies: a) if the nominal frequency of the input(s) lies between 5 Hz and 1500 Hz; b) if a measuring transducer is part of a system for the measurement of a non-electrical quantity, this standard may be applied to the electrical measuring transducer, if it otherwise falls within the scope of this standard; c) to transducers for use in a variety of applications such as telemetry and process control and in one of a number of defined environments.
