How to choose the right liquid for the pressure gauge?

　    How to choose the right liquid for the pressure gauge?

　　The type of liquid used to fill the meter varies by application. Although Glycerine-filled manometer provides the best performance in most applications, each application has its own requirements. The guidelines to help ensure that the A fluid corresponds appropriately to the application are:

　　If there is a problem with icing, please use a silicone-filled pressure gauge or Glycerine-filled manometer. They have low viscosity even at -60 degrees Celsius.

　　If the system has electrical accessories such as contacts, use insulating oil, and if extreme temperature fluctuations are expected, use silicone oil. The higher the viscosity of the liquid, the greater its cushioning capacity.

　　The reason is that the buffer fluid changes in proportion to the viscosity of the filling fluid. The correct degree.

　　Damping depends on the performance requirements that the meter must comply with, such as pointer response time, extreme pressure, vibration, and pressure changes. Lenz can recommend specific fluids for application game problems.

　　the silicone-filled pressure gauge is also our product, welcome to consult and purchase.
