Description / Abstract:

This Standard covers potentiometric displacement transducers, primarily those used in measuring systems.


1. These specifications are not intended to cover transducers used in hazardous (classified) locations as specified in the National Electric Code.

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.

Included among the specific versions of potentiometric displacement transducers to which this Standard is applicable are the following:

Angular Displacement Transducers

Linear Displacement Transducers 

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.


This Standard establishes the following for potentiometric displacement transducers.

Uniform minimum specifications for design and performance characteristics 2.2 Uniform acceptance and qualification test methods, including calibration techniques

Uniform presentation of minimum test data
