U.S. Gauge P-1550 liquid filled utility gauges are designed for a wide range of rugged service applications on pumps, compressors, hydraulic systems, machine tools, and petrochemical processing equipment. Liquid fill fluid dampens the gauge pointer movement and improves readability, making these instruments ideal for high shock and vibration applications. Series P-1550 liquid filled gauges are available in psi and bar, kPa, and kg/cm2metric ranges. Rated accuracy is ±3-2-3% of span (Grade B).
Gauges feature a corrosion resistant 300 series stainless steel case and ring, and durable polycarbonate window. Phosphor bronze Bourdon tube, brass movement, and socket connections are standard. Series P-1550 gauges come in 1-1/2" designs with 1/8-27 NPT center back male (CBM) connections (P-1559); 2" and 2-1/2" designs with 1/4-18 NPT low male (LM) (P-1555) and center back male (CBM) (P-1559) connections.
