ETCR2800T Non-contact Earth Resistance On-line Monitor is high-tech product that our company has devoted to "grounding resistance detection technology research" for more than ten years, specialize for online monitoring grounding down lead connection status, circuit grounding resistance and metal circuit connection resistance. On-line testing, non-contact measurement, grounding wire pass through the perforation of the detector, definitely will not influence grounding effective for lightening and normal operation, no need the self-inspection, real time on-line testing. Provide RS485 wire communication (support MODBUS-RTU communication protocol) , The monitor is composed of sensor and PCB module, which is suitable for user secondary development integration. Among them, ETCR2800T is specially designed for outdoor installation, the sensor housing is made of 304 stainless steel, sealed with internal resin, and has a solid structure. It is anti-explosion and anti-impact, high and low temperature resistant, waterproof and dustproof, all-weather, especially suitable for installation to use of outdoor, oil depot and gas station.
ETCR2800T Non-contact Earth Resistance On-line Monitor suitable for transmission line tower grounding; Meteorological lightning protection grounding; Petrochemical grounding; Communication grounding; Substation grounding; Railway facilities grounding; Construction warehouse grounding; Metal circuit resistance; Electrical equipment grounding and others place. It can also be used for anti-theft monitoring of grounding wires and metal cables.
ETCR2800T Non-contact Earth Resistance On-line Monitor can install and use singly, and also can set up wired or wireless network system.
