Certificate history:
This certificate is issued as verification that a sample(s), representative of production, was assessed and tested and found to comply with the IEC Standard list below and that the manufacturer's quality system, relating to the Ex products covered by this certificate, was assessed and found to comply with the IECEx Quality system requirements. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
This Unit verification certificate is issued as verification that the Apparatus identified on page 1, was assessed and tested and found to comply with the IEC Standard list below. This certificate is granted subject to the conditions as set out in IECEx Scheme Rules, IECEx 02 and Operational Documents as amended.
STANDARDS: The electrical apparatus and any acceptable variations to it specified in the schedule of this certificate and the identified documents, was found to comply with the following standards:
As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
The Model 5081 Series of Transmitters comprises 4 types:· 5081A/P Amperometric/pH Transmitter (HART, Fieldbus and FISCO versions) is designed to measure the amount of Chlorine, Dissolved Oxygen or Ozone in, or pH or ORP of, a liquid in conjunction with an appropriate sensor.· 5081-C Contacting Conductivity Transmitter (HART, Fieldbus and FISCO versions) is designed to measure the conductivity or resistivity of a liquid in conjunction with an appropriate sensor.· 5081-G-HT/FF-73 Oxygen Gas Transmitter is designed to measure the net concentration of oxygen in an industrial process e.g. in flue gas, in conjunction with a zirconium probe.· 5081-T Toroidal Conductivity Transmitter (HART, Fieldbus and FISCO versions) is designed to measure conductivity of a variety of process liquids.The Model 5081 Series Transmitter’s circuitry is contained on three different circuit boards for the –HT versions or four different circuit boards for the –FF/FI Fieldbus variants.The PCBs, together with the optional LCD display and the terminals for external connections are mounted in a rugged enclosure manufactured in epoxy-coated aluminium or stainless steel.See Annex for parameters.
