| General |
| Case |
AISI 304 Stainless Steel in 2-1/2" (63 mm), 4" (100mm), and 6" (150mm) sizes, Filled or Dry. Case and socket welded together on 6" gauges. |
| Ring |
AISI 304 Polished Stainless Steel, Bayonet Connection on 4" and 6" gauges. Crimped on 2-1/2" gauges. |
| Window |
Instrument glass, Safety Glass and Acrylic optional. |
| Socket |
AISI 316 Stainless Steel, TIG welded to the elastic element using 316 Stainless Steel. K Monel optional on 4" and 6" gauges. High Range 4" and 6" gauges come with removable Stainless Steel Restrictor. No restrictor on 2-1/2". |
| Bourdon Tube |
All Pressure Sensing Elements are AISI 316L Stainless Steel. All 2-1/2" gauges less than 600 PSI, and 4" and 6" gauges less than 1000 PSI range use a C-tube configuration. All other gauges use a spiral tube. K Monel optional on 4" & 6". |
| Movement |
Stainless Steel, Reinforced Stainless in 4" and 6" gauges only. |
| Pointer |
Balanced black aluminum. Micrometer adjustable in 4" and 6" only. |
| Dial |
White Aluminum with black markings. Markings and graduations in accordance with ASME B40.1-1998. |
| Process Fluid Temperatures |
212°F (100°C) maximum for standard tube and socket materials, 450° F (230° C) maximum for optional K Monel dry gauge. |
| Overpressure Limits |
| As a percent of full scale value |
30% for ranges up to 870 PSI (60 Bar). 25% for ranges from 870 to 1400 PSI (100 Bar). 15% for ranges above 1400 PSI (100 Bar). Overpressure in excess of these values may affect calibration but will not damage the movement due to the mechanical stops. |
| Receiver Gauge |
| Option 60RS and 60RS |
Receiver Gauges are the same in all descriptions as 40SS and 60SS gauges, except for specifications listed below. |
| Pressure Range |
3-15 psi. |
| Dial Scales |
0-100% linear; 0-10 square root; 0-100% and 0/10 square root dual scale. |
| Accuracy |
±1% on 4" and 6". |
