Gauge range selector
Type the normal working pressure or temperature. The dial redraws to the standard range we would supply and shows where your reading sits.
Type your normal working pressure to see the range we would supply.
The rules it uses
- Standard ranges 0–1, 1.6, 2.5, 4, 6, 10, 16, 25, 40, 60, 100, 160, 250, 400 and 600 kg/cm² (bar uses the same series; psi and MPa their own).
- Working pressure as close to 50% of full scale as the series allows.
- Never above 75% of full scale for steady pressure, or two thirds for pulsating pressure. The red band on the dial marks the zone to stay out of.
- Negative pressure: vacuum gauge 0 to 760 mmHg or a compound gauge.
The result is a starting point. Tell us the maximum and test pressure too, and we confirm the range in the quotation.
Temperature gauge range
Standard bimetallic ranges: −38 to +50, −50 to +50, 0 to 50, 0 to 100, 0 to 120, 0 to 150, 0 to 200, 0 to 250, 0 to 300, 0 to 400, 0 to 600 °C.
Put the normal temperature in the middle third of the scale. For example, chilled water at 6–12 °C: 0 to 50 °C; hot water at 80 °C: 0 to 150 °C.
Questions buyers ask
How do I choose the range of a pressure gauge?
Choose a full-scale range about twice the normal working pressure. Normal pressure then sits near the middle of the dial, and the maximum stays below 75% of full scale (two thirds on pulsating service), which limits Bourdon tube fatigue.
How do I choose the range of a temperature gauge?
Pick the range that puts normal operating temperature in the middle third of the dial, with the maximum still on the scale.
