Accuracy

Accuracy class:	per EN 837-1: NS 63: class 1.6 NS 100: class 1.0
Temperature influence:	Max. ± 0,4% / 10K of measuring span per EN 837-1
Process-temperature-influence:	depending on active diaphragm diameter
	dM 22.6…24 mm ≤ 25 mbar / 10 K dM 27…30 mm ≤ 20 mbar / 10 K dM 34…36 mm ≤ 8 mbar / 10 K dM 40…46 mm ≤ 5 mbar / 10 K dM 51…58 mm ≤ 2 mbar / 10 K
	A detailed calculation of accuracy can be submitted upon request.

Hygienic design

The wetted surfaces made of stainless steel are executed according to EHEDG Doc.8 and ASME BPE SF3 (Code: HY).

We guarantee the following surface roughness values: Diaphragm foil: Ra ≤ 0.38 µm Laser welds: Ra ≤ 0.76 µm Turned parts: Ra ≤ 0.76 µm

Further versions of hygienic design upon request.

Autoclav. design: Autoclavable without case filling, only. Please remove the Elastomer filling plug before autoclaving.

Temperature ranges

Temperature ranges for the design of the diaphragm seal system (in combination with the pressure transmission fluid FD1):

Ambient without filling: -10…50 °C Ambient with filling: -10…50 °C Media without filling: -10…140 °C Media with filling: -10…140 °C

Adjusted design temperature ranges within the following maximum values are possible on request: Ambient without filling: -20…60 °C Ambient with filling: -20…60 °C

Option: Autoclave temperature: 130 °C for 1 hour (without filling)

Storage without filling: -20…60 °C Storage with filling: -20…60 °C

Extended temperature range (-20...60 °C) optional.

The maximum values can be restricted by the following parameters:

- diaphragm size - measuring range - pressure transmission fluid
