DESCRIPTION

SPECIFICATIONS

U.S. Gauge Models 1555, 1558 and 1559 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.

SIZES: 1-1/2", 2", 2-1/2"

t Models 1555, 1558 and 1559 liquid filled gauges are
available in psi and bar, kPa, and kg/cm2 metric ranges.
Rated accuracy is ±3-2-3% of span (Grade B).

DIAL: Aluminum, white background with blue and black
markings

t Gauges feature a corrosion resistant 300 series stainless steel case and ring, and durable poly­arbonate
c
window. A phosphor bronze Bourdon tube, brass movement, and socket connections are standard. The lower
mount (LM) Model 1555 comes in 2" and 2-1/2" versions
with a 1/4-18 NPT connection. The model 1559 is a center back mount (CBM) gauge that comes in a 1-1/2" design with a 1/8-27 NPT connection or the 2" and 2-1/2"
