80mm Blue Painted Steel Case Refrigeration Pressure Gauge 200 psi Brass Connection Air Conditioner Manometer
Description
By immersing the Bourdon tube in a fluid (filling of the casing), the motion of the pointer can be damped. Glycerine is often used for this purpose. The liquid may be added through an opening on top of the casing which is then closed with a rubber plug. The filling continues until the Bourdon tube is fully submerged.
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
