documentation.

4. Design and function

Description

■

Nominal size 100 and 160 mm

■

The instruments measure the pressure by means of resilient diaphragm

measuring elements. The reference point is absolute pressure “zero”.

■

The measuring characteristics are in accordance with the EN 837-3 standard.

3. Specications

Pressure limitation

Steady: Full scale value

Fluctuating: 0.9 x full scale value

Overpressure safety

Minimum 1 bar absolute pressure (atmospheric pressure),

in addition 10 x full scale value, max. 25 bar absolute pressure
