Thisincludes the renumbering of some sections, i.e., Sectio
5、n 2 is the Reference Section and Section 3 is Definitions.All other sections have been renumbered.This document is intended as a guide for technical personnel of both using and supplier firms whose duties includespecifying, calibrating, testing, developing, or demonstrating the performance character
6、istics of Manifold AbsolutePressure (MAP) transducers. By basing users specifications as well as suppliers technical advertising andreference literature on this document, or by referencing portions thereof, as applicable, a clear understanding ofthe users needs and of the transducers performance cap
7、abilities will be provided. Adhering to the specificationoutline, terminology, and procedures shown will result in simple, complete specifications; it will also reduce designtime, procurement lead time, and labor, as well as material costs.This guide is also intended for use as a general example for
8、 specifying other types of transducers.The MAP Transducer Representative Specification is referenced to and dependent upon SAE J1346.1. ScopeThis guide is intended to cover specifications applicable to MAP transducers. It is also applicable totransducers such as Barometric (Ambient) Absolute Pressur
9、e transducers, Manifold Vacuum transducers, andsimilar pressure transducers used in automotive systems. Although this guide is oriented towards activedevices (those using internal signal conditioning), it can be applied to passive devices with minormodifications.1.1 ValuesThe guide is intended to be
10、 general in nature. Specific values for performance data are not includedin order to maintain generality. Exemplary values are contained in the Appendix in an attempt to clarify thetext.
