80mm Blue Painted Steel Refrigeration Pressure Gauge 300 psi Brass
Connection Water Chiller Manometer
Description
The large overhanging free end of the Bourdon tube makes this
measuring principle sensitive to vibrations.
When vibrations occur, the overhanging part will make small up and
down movements. The transmission mechanism ensures that this
movement is amplified and passed on to the pointer. As a result,
the pointer will constantly move back and forth, making accurate
reading impossible.
Applications
Measuring refrigerant ammonia pressure and temperature
Suitable for corrosive environments and gaseous or liquid media
that will not obstruct the pressure system
Process industry: chemical/petrochemical, power stations, mining,
on and offshore, environmental technology, mechanical engineering
and plant construction
Special features
Excellent load-cycle stability and shock resistance
All stainless steel construction
Ammonia refrigerant scales on dial
