Equipment On/Off Sensor

The GKT5L equipment start-stop sensor is primarily used to monitor the start and stop status of electromechanical equipment in coal mines underground. It converts the detected equipment start-stop signals into various standard signals to transmit to the coal mine monitoring system, enabling centralized and continuous automatic monitoring of the start-stop status of all electrical equipment in the mine from the surface.

Technical Parameters

1. Working Voltage: DC12~24V;

2. Working Current: ≤30mA;

3. Action Value of Detected Equipment: AC5A±1A (three-phase);

4. Signal Output: Passive switch quantity, one set normally open, one set normally closed; contact capacity: DC24V/1A;

5. Power Supply Cable Diameter of the Tested Equipment: φ16～φ95mm;

6. Display Function: Utilizes optical signal indication, red light for equipment off-state; green light for equipment on-state;

7. Response Time: ≤1s.

Working Principle

Determine if the device is turned on or off by sensing changes in current or voltage. When the power status of the equipment changes, the sensor promptly captures this information and sends a notification to the user. This allows users to remotely check the status of the equipment, avoiding excessive energy waste and associated safety issues.

Advantages

Non-contact detection:

Many equipment on/off sensors use non-contact detection, which does not interfere with the equipment's normal functioning while also reducing sensor wear and damage.

High reliability

Equipment On/Off Sensors are often very reliable and stable, and they may operate normally even in difficult environments.

High-precision detection

Equipment On/Off Sensors can detect with high accuracy and accurately determine the switch condition of the equipment.

Fast response

Equipment On/Off Sensors typically have a short response time and may detect switch status changes in the equipment in a timely manner.

Simple to install and use

Equipment On/Off Sensors typically feature a simple construction that allows for easy integration into a variety of devices and systems.
