1038A Duplex Pressure Gauge

1038A Duplex Pressure Gauge

Product catalog summary

Overview: The Ashcroft Type 1038 Duplex Gauge is designed to display two separate input pressures on the same gauge for comparison purposes. It features a 4.5-inch dial size, bronze Bourdon tube, and brass sockets, with two independent systems and movements. The gauge has non-adjustable red and black pointers for easy differentiation of the two pressure readings.

Temperature Limits: The gauge can withstand ambient temperatures from -20°F to 200°F and process temperatures from -20°F to 250°F. Storage temperatures range from -40°F to 250°F. Non-liquid-filled gauges with standard glass windows can operate continuously up to 250°F, with accuracy affected by approximately 0.4% per 25°F deviation from the reference ambient temperature of 68°F. Gauges with silver brazed joints can withstand up to 450°F.

Standard and Metric Ranges: The gauge supports a variety of pressure ranges in both psi and metric units (kg/cm², bar, kPa), with specific figure intervals and minor graduations for precise measurement.

Recommendations: For continuous use or process temperatures above 250°F, a diaphragm seal, capillary, or siphon is recommended to ensure gauge longevity and accuracy.
