The Model 1558 Liquid Filled Gauge has an SST case, brass socket, and a phosphor bronze bourdon tube for applications requiring the protection of liquid filling. The 1555/1558/1559 gauges have low mount, center back, or front flange configurations. They are available in gauge sizes for every need: 1½”, 2”, 2½”, and 4”.
Liquid fill fluid dampens the gauge pointer movement and improves readability, making these instruments ideal for high shock and vibration applications.
Model 1558 liquid-filled gauges have a crimped ring and dual scale psi/bar or kPa/psi dial as standard. The pressure gauge suits environments with high vibration, pulsation, pressure spikes, and condensation build-up. Liquid filling protects the internals of the pressure gauge, and dampens the pointer to improve readability. Liquid filling also eliminates condensation build-up due to temperature fluctuations on the inside window. The case is material is 304 SST with a crimped-on window and a liquid fill plug at the top of the case for easy field filling if needed. The 1½”, 2”, and 2½” versions meets ASME B40.100 Grade B accuracy (±3-2-3%) and the 4” unit meets Grade B+ accuracy (±1.6%). Pressure ranges are from Vacuum to 10 000 psi.
