Field Instrument Surge Protective Device cu thilri phunphun kilvennak caah aa tlak, cu hna lakah:
1.2-hri, 3-hri, le 4-hri kuatnak:Hi transmitter pawl hi tihnung pawngkam ah a phunphun tahnak caah hman tawnmi an si.
Thermocouples (TC) le Resistance Temperature Detectors (RTD):Hi lum le lum lo hngalh khawhnak thilri hna hi riantuannak ah a dikthliar le zumhawktlak tein lum le lum lo tahnak caah hman an si tawn.
RS485, RS232, le RS422 tibantuk pehtlaihnak lam hna:Hi interface pawl hi thilri phunphun karlak ah data pehtlaihnak caah hman an si, cu nih cun system chung ah aa tlakmi le ttha tein fonh khawhnak a pek.
4.Flow tahnak:Flow meter cu pipeline asiloah system chung i ti asiloah gas a luan ning tahnak caah hman a si, cu nih cun thil kalning uknak le zohkhenhnak caah a biapi tukmi data a pek.
5.Electromagnetic valves:Hi valve hna nih hin riantuannak ah ti a luannak kha an uk i pipeline chung i ti asiloah gas pawl an kalnak kha uk khawhnak caah a biapi tukmi an si.
