4 Inches 70 bar Silicone Oil Filling Manometer 3/8 PT Panel Mount
Liquid Filled Pressure Gauge
Description
The type of liquid used to fill the gauge varies with the
application. Although pure glycerin provides the best performance
in most applications, each has its own requirements. For instance,
if extreme temperature fluctuations are expected, use silicone
oils. Guidelines to help ensure that a fluid is properly matched to
an application are:
GLYCERIN, 99.5% Pure = 35°F to 150°F
SILICONE, 200 centistoke = -100°F to 150°F
MINERAL OIL = 0°F to 115°F
Applications
♦ For measuring locations with high dynamic pressure loads and
vibrations
♦ For gaseous and liquid media that are not highly viscous or
crystallising and will not attack brass parts
♦ Hydraulics
♦ Compressors, shipbuilding
Special features
♦ Vibration and shock-resistant
♦ Especially robust design
♦ Completely from stainless steel
♦ Scale ranges up to 0 ... 1000 bar
