Gegevens

The A75 pressure gauge has been developed for pressure measurement of ammonia compressors. The pressure gauge has a stainless steel housing and is filled with glycerine for reliable operation and long life. The seal between the plastic window and the housing prevents leakage by means of a bayonet catch with sealing ring.

A connection nipple is fixed to the housing in a unique way making external connection screws unnecessary. This gives extra protection against leakage caused by vibration. Surges that can occur due to temperature differences of the glycerin are automatically compensated for by the special bellows. A safety blow-out plug is fitted to the top of the gauge to guard against explosions.

The measuring element is of stainless steel contemned in a bourdon tube argon arc welded to a large stainless steel junction. The measuring element is thermally and mechanically underrated allowing a 25% out of range safety margin. The pressure gauge can be delivered in several sizes and formats with a choice of connection sizes and couplings. The instrument scale is calibrated as standard for R717 temperature scales and the dial can be provided with your company logo.
