ISA 37.12

Abstract

This Standard covers potentiometric displacement transducers, primarily those used in measuring systems. <br><strong>NOTES</strong> <br>1. These specifications are not intended to cover transducers used in hazardous (classified) locations as specified in the National Electric Code. <br>2. Transducers for use in nuclear power plants must conform to additional U.S. Nuclear Regulatory Commission Requirements not specifically called out in this Standard. <br>Included among the specific versions of potentiometric displacement transducers to which this Standard is applicable are the following: <br>Angular Displacement Transducers <br>Linear Displacement Transducers&#160; <br>Terminology used in this document is defined in ISA-S37.1. Additional terms considered applicable to potentiometric displacement transducers are defined in 4.3 of this document. An asterisk appears after those terms defined in S37.1. A double asterik appears after those terms defined in 4.3 of this standard. <br><strong>Purpose</strong> <br>This Standard establishes the following for potentiometric displacement transducers. <br>Uniform minimum specifications for design and performance characteristics 2.2 Uniform acceptance and qualification test methods, including calibration techniques <br>Uniform presentation of minimum test data <br>A drawing symbol for use in electrical schematics
