Explosion proof, the 619 and 620 Series heavy-duty pressure transmitters are ATEX II 2 G Ex d II C approved for use in volatile/hazardous environments such as oil and gas, petrochemical, and borehole applications. Both series are available in a wide variety of pressure, vacuum, and compound ranges for measuring any process media suitable with 316L stainless steel and Elgiloy. Standard output signal is 4 mA to 20 mA two-wire but they are also available with three-wire voltage outputs and optional low excitation power requirements. The 619 Series transmitter features a 1/2" NPT standard connection while the front flush 620 Series version eliminates extra space in which the measuring medium can crystallize or form residue. Additionally, both series provide significant levels of RFI, EMI, and ESD protection.
