Data Sheet CASHCROFT Trust the shield.® FEATURES ■ PLUS! ™ Performance (option) dampens vibration, shock and pulsation effects; provides liquid-fill performance in a dry gauge ■ Accuracy complies with ASME B40.100 Grade 2A (±0.5% of span) ■ Solid front safety case with pressure relief back TYPICAL USES ■ Refineries ■ Chemical, petrochemical plants and offshore oil rigs ■ Water and wastewater pressure control Accuracy: ±0.5% of span (ASME B40.100, Grade 2A) Process Connection: !4 NPT Male, / NPT Male Case Style: Solid front with pressure relief back Movement: Adjustable • Available with a wide range of diaphragm seals • Available with a large variety of instrument assemblies MIN/MAX 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). Liquid-filled gauges can withstand 200° F (93 °C) but glycerin fill and acrylic window will tend to yellow. Accuracy at temperatures above or below the reference ambient temperature of 68 °F (20 °C) will be affected by approximately 0.4% per 25 °F. Gauges with welded joints will withstand 750 °F (400 °C), 450 °F (232 °C) with silver brazed joints 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. Pointer: Micrometer adjustable, aluminum Weather Protection: Dry Case: Case is not sealed and recommended for weather protected environment only Liquid filled or field tillable and Weatherproof: IP66 Hermetically Sealed: IP66 Mounting: Stem, surface, remote All specifications are subject to change without notice.
