- Description
- Specifications
The SKVA-03 Gas Detecting System is designed to measure the concentration of toxic gases and combustible substances in air in explosion-proof and explosive areas, archive the results, signal (by light and sound) about amounting to the set concentration levels, generate and issue control signals for external devices on transition events of measured concentrations through predetermined levels. The system supports information exchange with a remote terminal via the RS-485 Modbus RTU interfaces and via the Ethernet (through interface converter).
The scope of the gas detecting complex is determined by the requirements set forth in regulatory documents related to equipment, measuring instruments, control, management, automation, and emergency protection (EP) of industrial enterprises. The use of the system in general industrial design is allowed only for explosion-proof rooms and outdoor areas. The use of the system in explosion-proof design is allowed only for Categories 1 and 2 explosive areas in accordance with the explosion protection marking.
