RD-3000HS Multi-channel Hydrogen Leakage Monitor System
NA1000D II Hydrogen Monitoring Transmitter is an intrinsically safe explosion-proof type on-line hydrogen leak monitoring product specially developed by Henan Relations Co., Ltd. for the hydrogen-cooled generator of the power station.
This product is a standard 4 – 20mA transmitter of the two-wire system, which transforms hydrogen content into a current signal and outputs it to the dedicated control device. The detecting unit is a smart sensor module (RDS-H2) integrating complete calibration information, which is convenient for maintenance and replacement. The product housing is processed and made by die casting aluminum alloys, with beautiful appearance and firm structure, which can adapt to most of the bad environment.
