Glass Ammonia Refrigeration Pressure Gauge 300 Psi 80mm Water Chiller Manometer
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
