Manómetros de glicerina (también para vacío)

WIKA glycerine pressure gauges are excellently suited for use in systems in which the operating pressures fluctuate strongly or even pulsate (e.g. in hydraulic system or close behind pumps). The glycerine filling in the pressure gauge acts as damping and thus increases the service life of the measuring device. All glycerine pressure gauges have a tight sealing plug on the top of the housing. This plug should prevent that glycerine escapes from the pressure gauge during transport. After installation this must be opened, so that the pressure gauge indicates correct pressures. It must be installed pointing upward so that no glycerine escapes! Opening can be done, depending on the design, by turning a lever, cutting off a rubber tip, inserting...
