ETCR2800KC Digital LCD Split-core Ground Resistance Tester Meter with Loop Ground Resistance On-line Monitoring Function
1.Brief Introduction:
ETCR2800KC Split-core Ground Resistnace Detector specifically designed for online monitoring of the connection status of the ground lead-down wire, Loop ground resistance and the connection resistance of the metal circuit, installation without disconnecting the ground lead-line, convenient and quick. On-line test, Non-contact measurement,ground wire through the detector directly,Without self-test, real-time detection, using RS232, RS485 wired communication or GSM wireless communication data transmission, remote online monitoring. Detector built-in sensor and PCB, completely enclosed, waterproof and dustproof.Ensure high-accuracy, high stability and high reliability of long time on-line monitoring outdoors, underground mine and indoors.
ETCR2800KC Split-core Ground Resistnace Detector applies to electric transmission line pole ground connection, underground mine device ground connection, Meteorological lightning protection ground connection, petrochemical engineering ground connection, communication ground connection, rail facility ground connection, building the warehouse ground connection, electrical equipment ground connection etc..
ETCR2800KC Split-core Ground Resistnace Detector need to use in wire network system or wireless network system.Wired network system through RS232, RS485 communication protocol to transfer data, by the main communication device (concentrator), monitoring software, power adapter, computer and other components, suitable for short-distance or underground mine ground resistance monitoring.
Wireless network system through RS232, RS485, GSM / GPRS communication protocol to transmit data from the master (concentrator), GSM / GPRS transceiver module, SIM communication card, monitoring software, power adapter, computer and other components for long-distance or Mine ground resistance monitoring. Wired network system is suitable for monitoring within 1,500 meters distance, wireless network system is not subject to distance restrictions.
The monitoring software can display the measured grounding resistance from time to time. You can set the monitoring recording time automatically. The interval recording time is 1 to 200 hours. The recorded data is automatically stored for historical inquiry. Analyze the change of grounding resistance of monitoring points.
ETCR2800KC has passed the explosion-proof certification to meet GB3836-2000 “electrical equipment for explosive gas atmospheres” requirements. Its explosion-proof mark Ex ia Ⅱ B T3 Ga. Explosion-proof certification number: CE13.2262X. It can be applied to the corresponding flammable and explosive environment.
