C ASHCROFT’ Trust the shield.® Type 1127/1128 Differential Pressure Gauge FEATURES • 4V2"& 6"dial size • 316 Stainless steel Bourdon tube and sockets • ASME B40.1 Grade 1A (2%-1%-2%). • Black epoxy coated aluminum case and ring The Ashcroft® Type 1127/1128 differential pressure gauges display the difference of two separate inputs on one dial indicator. The 1127/1128 is offered with “0” at the 12 o’clock position on the dial with positive pressure on either side of zero. The 1127/1128 has stainless Bourdon tubes. When the process media is corrosive to the gauge wetted parts, diaphragm seals with capillaries are available. TEMPERATURE LIMITS Note: Other than discoloration of the dial and hardening of the gasketing that may occur as ambient or process temperatures exceeds 150°F, non-liquid-filled gauges with standard glass windows, can withstand continuous operating temperatures up to 250°F (121°C). Accuracy at temperatures above or below the reference ambient temperature of 68°F (20°C) will be affected by approximately .4% per 25°F Gauges with silver brazed joints will withstand 450°F (232°C) for short times without rupture, although other parts of the gauge will be destroyed and calibration will be lost. For continuous use and for process or ambient temperatures above 250°F (121°C), a diaphragm seal or capillary or siphon is recommended.
