Stainless Steel Earth Resistance Detector

The ETCR 2800T is a non-contact online monitor designed for electricians and facility engineers who need continuous grounding resistance measurement without interrupting the earthing system. It clamps around the grounding down lead to track connection status and circuit resistance in real time.

Stainless steel body with RS485 communication

A stainless steel housing protects the sensor and PCB module in harsh environments while the grounding wire passes through the detector perforation without affecting lightning protection or normal operation. The integrated RS485 interface supports MODBUS-RTU protocol for wired data integration into monitoring systems.

Online non-contact measurement method

The defining specification is the ability to measure earth resistance on-line without physical contact or system shutdown, letting technicians verify grounding integrity continuously rather than during periodic offline tests.

Questions about this item

Does the ETCR 2800T use an RS485 interface for data output?

Yes, the ETCR 2800T provides an RS485 wired communication port that supports the MODBUS-RTU protocol for integration with monitoring systems.

How is the ETCR 2800T mounted on a grounding conductor?

The grounding down lead passes through the perforation in the sensor, clamping around the conductor without breaking the electrical connection.

What steps are required to power up the ETCR 2800T after mounting?

Insert the required batteries into the PCB module, wire the RS485 terminals to your MODBUS-RTU bus, then apply power to begin real-time resistance monitoring.
