Neue Möglichkeiten zur Grobvakuummessung in explosionsgefährdeten Bereichen

Absolut pressure gauges with fully electronic signal processing designed according to explosion protection tech nique »Intrinsic Safety« for use at hazardous locations offer many advantages at reduced cost. Capacitive pressure transducers with aluminium oxide diaphragm guarantee an optimum of corrosion resistance (especially important for chemistry applications). The absolute pressure is measured with high accuracy. Temperature‐ and long‐term drifts are minimized. The gauges do not have damageable moving parts and are insensitive to vibrations and pressure shocks. An integrated current loop interface allows automatic switch‐on and read‐out of the gauges.
