2.3 Intrinsic safety explosion-proof grounding resistance monitoring instrument

Product Overview

HD-HLDZ-RS485/Ex Explosion-proof Grounding Resistance Monitor is specially designed for online monitoring of grounding systems in explosion-proof hazardous areas.c the grounding wire only needs to pass through the central hole to complete detection, supporting real-time online monitoring. Equipped with an RS485 communication interface and compliant with Modbus-RTU standard protocol, it can be easily integrated into existing industrial control systems or for secondary development to realize remote centralized monitoring. The device features an aluminum alloy housing, which not only delivers explosion-proof and impact-resistant performance, but also resists rain, dust and sand erosion, ensuring stable all-weather operation.

Functional Features

• High precision, good stability and reliable performance
• ModBus-RTU communication protocol, convenient for secondary development
• Aluminum alloy housing, high safety protection grade
