He kūpono ka Field Instrument Surge Protective Device no ka pale ʻana i nā ʻano mea like ʻole, me:
1.2-wire, 3-wire, a me 4-wire transmitters:Hoʻohana maʻamau ʻia kēia mau transmitters no ke ana ʻana i nā ʻāpana like ʻole e like me ke kaomi, ka mahana, ka pae, a me nā mea ʻē aʻe, i nā wahi pōʻino.
2. Thermocouples (TC) a me ke kū'ē wela wela (RTD):Hoʻohana pinepine ʻia kēia mau mea ʻike wela i nā kaʻina hana e ana i ka mahana me ka pololei a hilinaʻi.
3. Nā pilina pili e like me RS485, RS232, a me RS422:Hoʻohana ʻia kēia mau kikowaena no ka kamaʻilio ʻikepili ma waena o nā mea like ʻole, e hōʻoiaʻiʻo ana i ka hoʻohālikelike a me ka hoʻohui pono ʻana i loko o nā ʻōnaehana.
4.Mika kahe:Hoʻohana ʻia nā mika kahe e ana i ka kahe kahe o nā wai a i ʻole nā gasana i loko o nā pipeline a i ʻole nā ʻōnaehana, e hāʻawi ana i ka ʻikepili koʻikoʻi no ka mālama ʻana a me ka nānā ʻana.
5.Electromagnetic kiwi:Hoʻoponopono kēia mau valve i ke kahe o nā wai i nā kaʻina hana ʻoihana a he mea nui ia no ka hoʻoponopono ʻana i ka neʻe ʻana o nā wai a i ʻole nā gaso i loko o nā pipeline.
