Detailed information
-
- Real-time transmission of detection results via 4-20mA analog output The VGU-01 outputs detection results for hydrogen sulfide and sulfur dioxide through a stable 4-20mA analog output. By connecting the VGU-01 to a PLC or control unit, an advanced alarm system can be constructed. - Corrosion-resistant stainless steel housing The VGU-01 features a robust stainless steel housing to prevent corrosion from rain and volcanic gases, and a corrosion-resistant rubber gasket prevents rainwater and corrosive gases from entering the device. - Internal condensation prevention heating mechanism The VGU-01 is equipped with a reliable heater that prevents internal condensation caused by temperature changes between day and night. This helps to prevent equipment failure due to condensation. - Replaceable gas sensor unit The gas sensor unit, which is most exposed to volcanic gases, is the part most likely to fail due to corrosion. The gas sensor unit of the VGU-01 can be easily attached and detached, allowing for quick replacement of the sensor unit. - List of detectable gases Simultaneous detection of hydrogen sulfide and sulfur dioxide.
