range from 2.5 mbar}

Hysteresis ≤ 0.1 % d. Spanne

Repeatability ≤ 0.05 % of span

1-year stability ≤ 0.5 % of span (at reference conditions)

Permissible temperature of

Medium -10 ... +50 °C 14 ... 122 °F

Ambient -10 ... +50 °C {-10 ... +60 °C} 14 ... 122 °F (14 ... 140 °F)

Storage -10 ... +70 °C 14 ... 158 °F

Compensated temperature range +10 ... +50 °C 14 ... 122 °F

Temperature coefficients in compensated temp range:

Mean TC of zero ≤ 0.3 % of span/10K

Mean TC of range ≤ 0.3 % of span/10K

{ } Items in curved brackets are optional extras for additional price.

1) The measuring ranges 0 ... 0.1 mbar; 0 ... 0.25 mbar; 0 ... 0.4 mbar are available on request.

For these measuring ranges a larger measuring cell and consequently also a case with larger dimensions is required.

2) Only with 4 ... 20 mA 2-wire, other output signals on request.
