Crowcon BESafe | Dual-Channel Gas Detector for Battery Energy Storage | H2, CO, CH4, 2 x 4-20 mA, Modbus
The Crowcon BESafe is a dual-channel fixed detector designed for battery energy storage systems, where early hydrogen, carbon monoxide or methane readings can signal thermal runaway. Any two smart sensors can be fitted to one transmitter, either on the unit or remotely on cables up to 15 m. A 128 x 64 OLED shows both channels, and an 85 dB sounder is built in.
Key features
- Two gas channels on one polycarbonate transmitter
- Pre-calibrated, swappable smart sensors with life indicator
- Remote sensor cables from 1 m to 15 m
- 2 x 4-20 mA, RS-485 Modbus and three relays
- 3000 data logs
