DA-800 detects various combustible & toxic gases leaked from industrial areas for gas producers, gas users, gas reservoirs, gas by-producers, and so on, in order to prevent any accidents in advance.
Using micro pump, DA-800 continuously suctions & detects the gas leaked from any designated area, which enables gas detection effectively even in the environment where diffusion gas sampling detectors cannot be installed or controlled.
Moreover, DA-800 converts digital signal into the 4-20mA standard current output signal which can be transmitted to various external devices such as PLC, DDC, recorder, and so on for integrated gas monitoring system.
On top of it, DA-800 provides RS-485 communication signal and gas leakage alarm signal by relay contact output. Besides, DA-800 has DC 4-20mA standard output which realizes max 2500m long distance output signal transmission from sensor to receiver and RS-485 communication signal which realizes max 1000m long distance signal transmission.
