If i want use the 6 kg/cm2 pressure gauge then how to calculate its pressure gauge range?..

Answer / carl_ellis

The general rule of thumb is to put the working range in at
the mid-range of the scale of the pressure gauge.

Remember, a bourdon tube is damaged beyond repair when
overpressurized.

Alternative rules are
If the working Range is
- Steady: the working range can be 3/4 of full scale value
- Fluctuating: the working range should be 2/3 of full
scale value
- Full scale value: the gauge is working near its limit.
Short duration at full scale value is advised. Replacement
with a higher range gauge is advised.

Typical standard dual scale gauge dial ranges are shown below:

kg/cm2  psi
0-1.06 0-15
0-2.1 0-30
0-4.2  0-60
0-7     0-100
0-10.6  0-150
0-11.0 0-160
0-14   0-200
0-21    0-300
0-28   0-400

The 0-11 bar-Kg/cm2 range puts a 6 kg/cm2 working value just
above mid range.

Yeah, yeah, I know. 1 bar is not exactly 1 Kg/cm2 but we're
talking mechanical gauges here.
