Refrigeration Pressure Gauge

63mm 1.8 MPa Panel Mounting Stainless Steel Case Brass Connection Refrigeration Pressure Gauge Description As the pressure connection is open to the atmosphere, the pressure gauge is measuring atmospheric pressure. Remember that, by convention, all gauges are calibrated to 0 bar at this pressure. So the needle may indicate 0 but the pressure isn’t zero. The gauge is only comparing the pressure that it is measuring with atmospheric pressure. The pressure shown on a gauge is

70mm 35 bar Brass Connection Blue Cover Refrigeration Pressure Gauge for Manifold Description Does the temperature shown by the needle always correspond to the temperature of the refrigerant? Firstly, this is only true if you read the refrigerant temperature on the correct scale. For example, if you measure a pressure in an R22 system, you must read the temperature on the R22 scale, and not on the scales for R12 or R502 (which are other refrigerants). Secondly, it is, of

63mm Stainless Steel Case Brass Connection Refrigeration Pressure Gauge with Panel Mounting Flange Description Is fitted with a pressure connector used to connect it to the refrigeration circuit via a special flexible hose. Has been given two pressure scales (we will use the bar scale) and a temperature scale. Note that the needle indicates 0 bar since the gauge is open to the atmosphere. Is graduated for refrigerant R22. Applications Measuring refrigerant ammonia pressure

80mm Painted Steel Case Refrigeration Ammonia Pressure Gauge 500 psi Cryo Refrigerator Manometer Description Usually, a Bourdon tube pressure indicator is mounted vertically. Deviations of +/- 5° relative to the vertical position are permitted. A deviation of more than 5° will have an impact on accuracy. Applications Measuring refrigerant ammonia pressure and temperature Suitable for corrosive environments and gaseous or liquid media that will not obstruct the pressure system

80mm Stainless Steel Refrigeration Ammonia Pressure Gauge 1400 psi 100 MPa Manometer Description When measuring the pressure of a liquid, the initially air-filled Bourdon tube will be filled up with liquid. As a result air will be trapped by the liquid at the tube end. This results in sluggish performance of the pressure indication. A pressure gauge with diaphragm and liquid filled Bourdon tube is a better choice in this case. Applications Measuring refrigerant ammonia

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

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
