The Model 1550/1553 is a low cost Stainless Steel Gauge that has a crimped ring and dual scale psi/kpa dial standard. The pressure gauge is suitable for environments with high vibration, pulsation, pressure spikes and condensation build up. Liquid filling protects the internals of the pressure gauges, and dampens the pointer to improve readability. This gauge is NEMA 4X / IP66 weather proof for durability. Liquid filling also eliminates condensation build up due to temperature fluctuations on the inside window. The 1550/1553 is a liquid filled pressure gauge and is available in 2½” (63mm) and 4” (100mm) gauge sizes.

Each gauge has 316L SST socket and 316L SST bourdon tube. The case 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 2½” version meets ASME B40.100 Grade B accuracy (±3-2-3%) and the 4” meets Grade 1A accuracy (±1.0%).

Gauge size: 2½" (63 mm) or 4" (100 mm)

All Model 1550/1553 pressure gauge are RoHS compliant to EU directive 2011/65/EU.

Pressure ranges are from Vacuum to 15 000 psi. Pressure gauges are available in bottom mount (Model 1550) and a center back (Model 1553) versions.
