SMART Gas Detector/Transmitter(4~20mA)with built-in LCD & explosion proof, Suction Type

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. Built-in micro pump for gas sampling enables effective gas detection especially for the environment where diffusion type gas detectors cannot be used. DA-800 converts digital signal into the 4-20mA standard current output signal which can be transmitted to various devices such as PLC, DDC, or recorder to build comprehensive gas monitoring system. Also, DA-800 provides RS-485 communication signal and alarm relay contact. DC 4-20mA standard output signal realizes max 2500m long distance output signal transmission and RS-485 communication signal realizes max 1000m long distance signal transmission.
