Please notice that with many cylinders the forces in the end position are lower due to reduced effective piston surface area and static friction. Reductions of 5 - 25% are realistic here. For the calculation of the return stroke the factor for the return stroke must be used due to the reduced effective surface by the piston rod. Pressure-force table for pneumatic cylinders (for return stroke)* By answering a few questions, the selection of the right pressure gauge for your application is very easy.

These pressure gauges are equipped with an unbreakable baffle wall between the measuring system and display and a blow-out back. Dynamik Without Can be used for most applications. Do not use, with pul- glycerine filling sations (pumps) or pressure peaks (switching directional (uncushioned) valves in hydraulic applications). Ideal for applications with pulsations or light pressure peaks (hydraulic applications). For increased pulsations or pressure peaks, it is recommended to place a pressure With gauge snubber upstream or the use of pressure gauge glycerine filling stop cocks. Warning: After installation the housing must (cushioned) be opened on the vent openings (top), so that the pres- sure gauge displays the correct measured values. That is normally done by opening a small tap or cutting a rubber seal. Accuracy class (class) Indicates the maximum permissible deviation between dis- played measured value and actual pressure in percent 2.5, 1.6, 1.0 based on the end value of the display range. A pressure or 0.6 gauge, for example with a display range up to 10 bar and a class of 1.6 may thus have a maximum deviation of 0.16 between the actual and displayed pressure. Pressure range It is common practice to load the pressure gauge up to maximum 80% of the display range in order to protect it against overload. It is thus recommended for example for a measurement up to 10 bar to use a pressure gauge with a display range up to 16 bar.
