LH1500

Features

Comprehensive monitoring of the generator’s hydrogen leak condition
Real-time monitoring of the air leakage at the generator’s bus bar, oil return pipe, water return pipe, sampling valve, internal cold water tank, etc.
It can be directly put into oil and water for detection; it uses unique hydrogen sensitive tube bundle that is of good pressure-bearing ability, water and oil insulation, and is oil-insoluble.
Simultaneous monitoring of the generator’s safe working status
Real-time monitoring of potential hydrogen accumulation positions;
Multi-position simultaneous detection;
Local display of monitoring data and transfinite acousto-optic alarm
Convenient installation and use
16-channel centralized monitoring;
Excellent expandability and direct accessibility;
High-performance specific integrated circuit to ensure easy data uploading to DCS system.
