| 1) Accuracy class 2.5 with smallest scale range. Depending on the built-in contact model, 0 … 25 mbar or 0 … 40 mbar.
2) Application test required 3) Depending on scale range and overload safety, different flange Ø apply. See dimensions from page 5. 4) 400 bar overload safety for scale ranges < 400 mbar on request 5) For hazardous areas, the permissible temperature of the contact model 831 will exclusively apply (see page 5). These must not be exceeded at the instrument either (for details see operating instructions). If necessary, measures for cooling (e.g. syphon, instrumentation valve, etc.) have to be taken. |
