Alfa Laval pressure gauges measure pressure by means of the Bourdon principle. Silicone oil is used as the medium to convert the pressure applied to the diaphragm to a Bourdon tube. The Bourdon tube is in mechanical contact with the indicating needle and turns the needle on the pressure dial of the gauge to present the pressure measurement.
