Description

Stainless steel case brass internals, liquid filled pressure gauge, 1/4″ bspp bottom entry pressure gauge.

> APPLICATIONS

Pressure gauges ideal for the measurement of rapidly fluctuating or pulsating pressures, or in presence of vibrations. Good shock resistance. Suitable for all liquid or gaseous fluids, provided the latter are not highly viscous, crystallising or corrosive to copper and tin alloys. They can be fastened directly on the pressure inlet or on the instrument panel with special brackets or flanges supplied as optional

> MAIN FIELDS OF APPLICATION

– oil hydraulics (plant and equipment)
– technical equipment
– water cleaners
– agriculture and zootechny
– means of transport
– compressors

> NORMATIVE REFERENCES

– EN 837-1
– 2.5 precision class
– CE 1997-23 directive (PED)
– degree of protection IP65 according to EN 60529

> OPERATING LIMITS
