MD-S925E Digital Electrical Contact Pressure Gauge
Product Overview
The MD-S925E Digital Electrical Contact Pressure Gauge is a high-performance 100mm stainless steel electronic pressure switch gauge designed to replace traditional mechanical electrical contact pressure gauges. Built with a durable 304 stainless steel housing and connector, it offers superior resistance to vibration, impact, and harsh industrial environments.
This digital LED pressure gauge is ideal for applications with frequent pressure fluctuations and strong mechanical vibration. It features clear digital display, high accuracy, multi-unit switching, and simple operation, making it a reliable solution for modern industrial pressure monitoring and control systems.

Key Features & Advantages
• 100mm 304 stainless steel housing with waterproof aviation connector
• Durable 304 stainless steel pressure connector
• High-visibility 4-digit LED real-time pressure display
• Multi-unit switching (bar, MPa, kPa, etc.)
• One-key zero calibration function
• Fully compatible wiring with mechanical electrical contact pressure gauges
• High accuracy: 0.5% FS precision measurement
• Strong resistance to vibration and shock
• Relay output for automatic control applications
• Adjustable control points with hysteresis setting
• Suitable for gas, water, and oil pressure monitoring
• Long service life with stable performance

Working Principle
The MD-S925E Digital Electrical Contact Pressure Gauge operates by converting pressure signals into electrical signals using an internal pressure sensing element. The measured pressure is processed by a microprocessor and displayed in real time on the LED screen.
When pressure reaches preset high or low limits, the system activates the relay output, enabling automatic control of external devices such as pumps, compressors, or alarms. This makes it a direct replacement for traditional mechanical contact pressure gauges, offering improved accuracy and reliability.
