2. Instrument specification and P&I diagram

3. Bourdon Tube Pressure Gaugeswith Electrical Output SignalStainless Steel, Safety Case VersionType PGT43.100

4. Instrument specification Range 0-0.4 bar Span 0.4 bar Resolution bar

5. Bourdon Tube Pressure Gauges Accuracy 2% Fullscale Pressure Gauges 0 to 0.4 bar Error = bar Solution 0% error at 0 bar bar 25% error at 0.1 bar bar 50% error at 0.2 barbar 75% error at 0.3 barbar 100% error at 0.4 barbar

6. Bourdon Tube Pressure Gauges Accuracy 2% Span Pressure Gauges 0 to 0.4 bar Error = bar Solution 0% error at 0 bar bar 25% error at 0.1 bar bar 50% error at 0.2 bar bar 75% error at 0.3 barbar 100% error at 0.4 bar bar

7. Bourdon Tube Pressure Gauges Accuracy 2% Reading Pressure Gauges 0 to 0.4 bar Ex. อ่านค่าได้ 0.25 bar จะมี error อ่านค่าได้ 0.25 bar จะมี error

8. Bourdon Tube Pressure Gauges Accuracy 2% rdg+constant Pressure Gauges 0 to 0.4 bar Accuracy = (0.08+0.002lPl) bar Error at 0 bar = (0.08+0.002(0)) bar = 0.08 bar Error at 0.1 bar = (0.08+0.002(0.1)) bar = 0.0802 bar Error at 0.2 bar = (0.08+0.002(0.2)) bar = 0.0804 bar Error at 0.3 bar = (0.08+0.002(0.3)) bar = 0.0806 bar Error at 0.4 bar = (0.08+0.002(0.4)) bar = 0.0808 bar
