1131 Differential Pressure Gauge

The Ashcroft® 1131 differential pressure gauge is an economical means for measuring pressure between two independent pressure sources. Uses a rolling diaphragm design to separate high and low pressure ports and isolates media between low and high pressure sides.

Key Features:

• High static pressure capability (up to 3,000 psi)
• Reed switches (optional) for direct system control
• Superior magnets for smoother pointer motion

Specifications:

• Accuracy: ±2% (ascending pressure)
• Pressure Ranges: 0-5 thru 0-150 psid
• Dial size: 2", 2 1/2", 3 1/2", 4", 4 1/2" and 6"
• Case: stainless steel
• Body: aluminum, brass or stainless steel
• Wetted Material: body material, Teflon®, ceramic and various O-ring materials

The 1131 differential gauge is ideal where safe and reliable pressure measurement is essential:

• Filtration Monitoring
• Leak Detection
• Flow Measurement
• Clean Room Positive Pressure (low dp)
