Grounding system monitoring alarm

The adjustable range of the grounding system alarm is 0-500Ω, which can be set to the ground monitoring resistance value according to the requirements of the working grounding resistance value, and measure the loop resistance value in real time, and when the set resistance value is exceeded, the sound and light alarm will be carried out immediately. The simple design of this instrument makes it easy to monitor and effectively improves the reliability of the grounding system.

Features:
• Automatic audible and visual alarm;
• Power-off memory function;<2S;
• Real-time display of resistance value;
• Adjustable resistance value alarm range (0~500Ω);
• Improve the efficiency of daily inspections.

Working principle

The simple design of this instrument makes monitoring easier and effectively improves the reliability of the grounding system. It has a wide range of applications, such as in fuel, chemical loading and unloading sites; refueling stations, paint, paint, oil refining, chemical, pharmaceutical products production and processing areas; equipment (production lines) and ground contact conditions, such as other ground resistance requires higher workplace.

Automatic alarm

Grounding system monitoring alarm is a real-time monitoring of the grounding system and alarm equipment, instrument digital display input resistance value and set alarm resistance value.

Alarm range adjustment

The adjustable range of the alarm point is 0-500Ω. According to the requirements of the working grounding resistance value, the monitoring resistance value can be set and the loop resistance value can be measured in real time. When the set resistance value is exceeded, the sound and light alarm will be given immediately.
