Vacuum pressure gauges - How they work

The EN 837 standard provides accuracy requirements for pressure gauges expressed in accuracy classes. An accuracy class of 2.5 means that the gauge may deviate up to 2.5% of the span from the real value. For a vacuum gauge the span is 1 bar (15 psi), this means 1 bar * 2.5% = 0.025 bar deviation. The deviation can both be positive or negative.
