      NS 100 [4"], 160 [6"]: 1.0
Scale ranges: 0 ... 0.6 to 0 ... 1,000 bar [0 ... 10 to 0 ... 15,000 psi] or all other equivalent vacuum or combined pressure and vacuum ranges
Pressure limitation:
NS 63 [2 ½"]
      Steady: 3/4 x full scale value
      Fluctuating: 2/3 x full scale value
      Short time: Full scale value
NS 100 [4"], NS 160 [6"]
      Steady: Full scale value
      Fluctuating: 0.9 x full scale value
      Short time: 1.3 x full scale value
Permissible temperature:
      Ambient: -70 ... +60 °C [-94 ... 140 °F]
      Medium: ≤ 100 °C [≤ 212 °F]
Temperature effect: When the temperature at the measuring system deviates from the reference temperature 20 °C [68 °F]: ≤ ±0.4 %/10 °C [≤ ±0.4 %/18 °F] of full scale value
