【Ethylene Tank Farm Technology】What type of field instruments should be used in the ethylene spherical tank area?
Thread Content
What type of field instruments should be used in the ethylene sphere tank area? In current new projects, electronic instruments (smart type) are used for on-site instrumentation. Instruments for analog signals use FF bus signals or standard 4-20mA DC signals with the HART protocol superimposed. The gas signal uses a standard signal of 20-100 kPa. The selected electronic instruments are classified according to the hazard zone classification, comply with the IEC60079 standard or the GB3836 standard, and are products that have **official certification from authoritative bodies** confirming compliance with explosion protection standards.
Intelligent electronic instruments are typically used in the ethylene sphere tank area. Instruments for analog signals typically use FF bus signals or 4-20mA DC standard signals in combination with the HART protocol, while gas signals make use of 20-100kPa standard signals. These electronic instruments must comply with the IEC60079 standard or the GB3836 standard, and shall have an explosion-proof certification from an **authorized institution. .
