*1 The thickness of the flange depends on its dimensions.
*2 Inconel probe bolts and U shape pipe are used. Use this option for high temperature use (ranging from 600 to700°C).
*3 Specify either /CV or /SV option code.
*4 Specify either /SCT or /PT option code.
*5 No need to specify the option codes, /CV and /SV, since the check valves are provided with the Automatic Calibration Unit.
*6 Sun shield hood is still effective even if scratched. Hood is necessary for outdoor installation out of sun shield roof.
*7 Recommended if sample gas contains corrosive gas like chlorine.
*8 Piping for reference gas must be installed to supply reference gas constantly at a specified flow rate.
*9 When selecting code -B (FM certified explosion-proof) or -C (CSA certified explosion-proof), select code -T(1/2 NPT).
*10 Confirm inside diameter of pipe attached to customer’s flange in case that -A or -E is selected.
*11 The cable entry devices (cable glands etc.) and blind plugs shall be in type of protection Ex “db” or Ex “tb”, suitable for the
conditions of use and correctly installed. They shall provide a degree of ingress protection of at least IP66.
*12 Output signal limits: 3.8 to 20.5 mA. Specify either /C2 or /C3 option code.
*13 When using ZR202S as CE marking compliance product, select -A (ATEX certified flameproof).
*14 "-Q" is the explosion-proof type of EAC with Pattern Approval for Russia. "-R" is the explosion-proof type of EAC for
Kazakhstan and Belarus.
