Product Description
4" 100mm Electric Contact Pressure Gauge | Dual Limit Control for Automation
Precision Pressure Control for Automation
Our 4-inch (100mm) Electric Contact Pressure Gauge is an advanced electronic pressure gauge designed for automated industrial control systems. Featuring upper limit, lower limit, and live pressure pointers with an easy-to-use adjustment knob, this transmission pressure gauge enables precise monitoring and automatic switching of pumps, compressors, and fluid tanks. Rated for 380V 10VA with a clear four-wire system—yellow common, green lower limit, red upper limit, and black ground—it delivers reliable performance for demanding automation applications.
Key Features & Benefits
- Dual Limit Control: Independent upper and lower limit pointers allow precise setting of pressure thresholds for automated system control, making this electronic pressure gauge ideal for maintaining pressure within desired ranges.
- Easy Field Adjustment: The convenient adjustment knob enables quick and accurate setting of control points without special tools or gauge disassembly.
- Clear Four-Wire System: Simple, standardized wiring—yellow common, green lower limit, red upper limit, black ground—ensures straightforward installation and troubleshooting.
- Heavy-Duty Switching: Rated for 380V 10VA, this transmission pressure gauge can directly control motor contactors, solenoid valves, and alarm systems.
- Combined Visual & Electronic Monitoring: Provides both local analog reading and electrical control signals in a single instrument.

How It Works: Automated Pressure Control
1. Set Control Points: Use the adjustment knob to position the upper limit and lower limit pointers at desired pressure thresholds.
2. Monitor Live Pressure: The live pressure pointer moves with system pressure, indicating current conditions.
3. Automatic Switching: When pressure reaches the lower limit, the green wire circuit closes (e.g., starting a pump). When pressure reaches the upper limit, the red wire circuit closes (e.g., stopping the pump).
4. Visual Verification: The dial provides continuous visual confirmation of system status.

Typical Automation Applications
- Water Pump Control: Maintain tank pressure between preset minimum and maximum levels
- Air Compressor Systems: Automate compressor cycling based on receiver pressure
- Industrial Fluid Tanks: Control filling and discharge operations
- Hydraulic Systems: Maintain pressure within safe operating ranges
- Process Control: Trigger alarms or shutoffs at critical pressure limits
