4-inch (100mm) Electric Contact Pressure Gauge with Dual Limit Control and 380V 10VA for Automation

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.

Wiring & Installation Guide

This transmission pressure gauge features an intuitive wiring scheme:

Wire Color	Function	Connection Point

Green	Lower Limit Contact	Lower limit control circuit (pump start, low alarm)
Red	Upper Limit Contact	Upper limit control circuit (pump stop, high alarm)
Black	Ground Wire	Earth ground for safety

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
