Please Note:

  Series 540 / 541 / 542  are designed and manufactured in accordance with sound

engineering practice as defined by the Pressure Equipment Directive 97/23/EC.  This product must not
be used as a “safety accessory” as defined by the Pressure Equipment Directive, Article 1, Paragraph
2.1.3. The CE Mark on the unit does not relate to the Pressure Equipment Directive.

INTRODUCTION

Series 54X are fluid pressure measuring transducers in which a four active arm  Wheatstone bridge of
thin film gauges, integral with a beam structure connected to a pressure summing diaphragm, is used to
convert fluid pressures into a proportional electrical signal.  These instruments are suitable for long,
continuous arduous service when operated within the published specifications.

Series 54X conform with the essential protection requirements of the EMC Directive 89/336/EEC
amended by certified type testing to EN 50082-2 and EN 60081-1.

Conformity with the requirements of the CE mark only applies when the installation
conditions described in these instructions have been met.  For units supplied without
a cable assembly connection to the transducer must be accomplished using Setra
Systems approved cable.  see APPROVED CABLE section.

All instruments conform to the appropriate specifications and/or drawings applicable and have been
subjected to relevant strict quality control procedures.
