Temperature effect	When the temperature of the measuring system deviates from the reference temperature (+20 °C): max. ±0.8 %/10 K of full scale value
Case	■ Model 432.56: Version S1 per EN 837: With blow-out device in case back ■ Model 432.36: Safety version S3 per EN 837: With solid baffle wall (Solid front) and blow-out back Instruments with liquid filling with compensating valve to vent case
Case filling	Without Option: With silicone oil M50 case filling, ingress protection IP65 (models 433.56, 433.36)
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.
