• Ranges (according to EN 837-1)

o Maximum value:

- 1600 bar.

o Scale ranges for pressure values between –1 and 1600 bar:

- pressure gauges: see table C1 at page P04;

- vacuum gauges and compound gauges: see table C1 at page P04;

- other graduations not normalized for single or double range (on request).

o Unit of pressure:

- bar, kPa, MPa, kg/cm2 and psi for single or double range.

o Scale angle:

- 270 °.


• Working pressure (referred to full scale deflection)

- steady from 1/10 to 3/4;

- fluctuating from 1/10 to 2/3;

- pulsating from 1/10 to 1/2.


• Over-pressure (occasionally allowed)

- 130% of full scale value.


• Pointer

- aluminium with micrometer adjustment;

- aluminium not adjustable for NS 63.


• Dial

- white aluminium with black figures (for dial modifications see available options).


• Accuracy (according to EN 837-1)

- class 1 (± 1% of full scale deflection) for NS 100, 150, 200 and 250;

- class 1,6 (± 1,6% of full scale deflection) for NS 63.


• Ambient temperature

- -40 ÷ +60 °C dry execution;

- -20 ÷ +60 °C glycerine filled execution;

- -40 ÷ +60 °C silicone fluid filled execution.


• Thermal drift

- out of optimum ambient temperature values included within +15 ÷ +25 °C, the thermal drift affects the instruments accuracy of 0,3% every 10 °C.


• Operating temperature

- -40 ÷ +250 °C dry execution;

- -20 ÷ +100 °C glycerine filled execution;

- -40 ÷ +120 °C silicone fluid filled execution.
