BLR/OPG Oil Pressure Gauge
◆The pressure gauge is avibration-proof pressure gauge with oil filled Inside for refrigeration use only.
◆The oil-fliled pressure gauge is used on freezer, cold store and air-conditioning unit.
◆The oil-filled pressure gauge is convenient In application as it features one gauge for multiple refrigerants.
◆The oil-filled pressure gauge has full stainless steel casing and wider beryllium bonze spring tube.
◆The oil-filled pressure gauge is an axial pressure gauge with edges for flange joint.
◆ The inside filled oil functions damping to the high trequency vibration of machinery.
◆ The damping oil cup prevents gauge pointer from jumping.
◆The flanged edge is for convenient mounting.
◆Over-pressure limit stop is equipped.
◆Zero error is ensured with strengthening overpressure measures.
◆ Rational oil seal design and no oil leakage worry.
◆ Pressure versus Temperature readings for easy use.
◆ Extra long service life.
