Product Details

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
