5.4.1 The design shall comply with PETROBRAS Standard NI-1882 and these recommendations.

5.4.2 The instrumentation shall be of the electronic type. Metering and Control Signals connected to PES and PLC´s of package units transmitted from the field shall be in 4 - 20 mA with the HART serial protocol in the same cable, fed at 24 VDC.

5.4.2.1 For analog instruments designed for control and monitoring connected to DCS , they shall specified with Foundation Fieldbus protocol compatibility .

5.4.2.2 For discrete instruments like limit switches and solenoid valves, the design shall consider Foundation Fieldbus devices, if there is no approved device available an alternative can be used a connection to multi input/output discrete to Foundation Fieldbus Converters and connected to DCS.

5.4.2.3 The start/stop push buttons for the electric motors the design shall consider the connection direct to MCCs.

5.4.3 In the case of 4 to 20 mA transmission, the option is for two wire type, with use of the four-wire system being accepted if the first option is not available in the market, and for a specific application. In that case the 4 -20 mA signal shall be galvanically insulated.

5.4.4 Transmitters shall be of the intelligent and microprocessor-based type. Handheld programmers shall be provided for configuring these instruments, considering 1 (one) programmer for every 25 (twenty five) transmitters from that manufacturer. In case the number of transmitters is less than 25 units, at least 01 (one) programmer shall be supplied per instrument manufacturer.

5.4.5 Absolute, gauge or differential pressure transmitters shall have digital output signal indication in engineering unit in the transmitter itself.

5.4.6 Pressure switches and thermostats shall not be used unless previously authorized by PETROBRAS. Flow switches shall only be used to detect the presence of flow where reliability is not important. Transmitters shall be used instead of level switches, pressure switches, thermostats, etc.

5.4.7 All field instruments shall have permanent stainless steel plates indicating the instrument TAG number.

5.4.8 Do not specify instruments under development or whose use is not yet consolidated.

5.4.9 Do not acquire instruments for the same function from different manufacturers.

5.4.10 Regulating filters shall have output pressure indication in Kgf/cm2.

5.4.11 All electronic instruments and equipment shall be built to display immunity to electromagnetic and radio frequency interference (EMF-RFI), as follows: induction less than 1% of SPAN, based on 5W/470MHz at 1 meter away.

5.4.12 When more than one valve or flow transmitter is necessary for the same service , the engineering flow sheets shall show all the instruments and be submitted to PETROBRAS for approval.

5.4.13 Valves intended for special applications such as, for example, isolation valves, fire-safe valves and tight shut-off valves shall be selected according to the specifications of the basic design and submitted to PETROBRAS for approval.

5.4.14 The shut-off valves shall be design with approved gasket kit to warranty no leakage when the process fluid is toxic, volatile or others(as defined in environment criteria).

5.4.15 Instruments installed outdoors and in non-classified areas shall have enclosures with a degree of protection of IP 65, in accordance with NBR IEC 60529.

E

5.4.16 The use of intrinsically safe (Ex-i) or EX na [L] instrumentation with FNICO or FISCO Foundation Fieldbus Concepts in classified areas as zone 0 , 1 and 2 shall complies with IEC 60079-27 . For 4-20 mA instruments the enclosure may be certified as Ex d bud submitted to PETROBRAS for approval.

5.4.17 Electrical instruments and electrical equipments shall be compatible with the electrical classification of the area and have a Conformity Certificate. This certificate shall also contain the degree of protection (IP) of the enclosure.

5.4.17.1 This Certificate of compliance shall be supplied according to regulation

“Portaria numero 83 de 03 Abril de 2006” published by INMETRO, to attend Brazilian laws.

5.4.17.2 This certificate shall be issued by an Accredited Certification Organization (OCC), that is an entity accredited by INMETRO responsible by the issue of the conformity certificates and by the inspections of the certified products, attesting the similarity of the analyzed requirements, with the dispositions of the resolution mentioned above. The accredited certification organizations are the following:
