The unit of the main scale of a pressure gauge is the unit of measurement in which the measured pressure value is displayed. Typical units for the main scale of a pressure gauge are: - Bar (bar) - Pascal (Pa) - Kilopascal (kPa) - Pounds per square inch (psi) - Kilograms per square metre (kg/cm²) The selection of the unit for the main scale depends on the specific requirements of the application and the region.

The scale range of a pressure gauge defines the scale start value and full scale value of the scale printed on the dial of the pressure gauge. The correct scale range depends on the process pressure of the respective application and the process conditions. There are predefined standard scale ranges for pressure gauges in accordance with European and American standards. For special display ranges, please contact WIKA support. Ideally, the process pressure of the application should be approx. 2/3 of the full scale value of the pressure gauge. Example: For a process pressure of 40 bar, for example, a pressure gauge with a scale range of 0 to 60 bar would therefore be recommended.
