1   Scope In addition to the requirements of IEC 61326‑1, this part specifies more detailed test configurations, operational conditions and performance criteria for transducers with integrated or remote signal conditioning. This standard applies only to transducers characterized by their ability to transform, with the aid of an auxiliary energy source, a non-electric quantity to a process-relevant electrical signal, and to output the signal at one or more ports. This standard includes transducers for electrochemical and biological measured quantities. The transducers covered by this standard may be powered by a.c. or d.c. voltage and/or by battery or with internal power supply. Transducers referred to by this standard comprise at least the following items (see Figures 101 and 102):
