  • Description
  • Specifications

The gas detecting system is designed to measure the concentration of toxic gases and combustible substances in air, archive the results, signal (by light and sound) about exceeding the set concentration levels, generate and issue control signals for external devices. The SKVA-01M gas detecting system supports information exchange with a remote terminal via the RS-485 and Ethernet interfaces.

The scope of the SKVA-01M stationary type gas detector 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, as well as the labour protection.

The gas-detecting complex consists of a set of blocks and modules subdivided by functional attribute into the following groups:

  • Transducers;

  • Devices for managing, collecting, and processing information;

  • Service devices.

The structure of any system, depending on the location and operating conditions of the gas detector, may include units and modules in explosion-proof and general industrial design.

For Projects for the SKVA-01M Gas Pollution Systems, see the Typical Solutions

The metrological characteristics of the system are determined by transducers and expansion modules included in the system.

The maximum quantity of transducers connected to one system is practically unlimited.

The maximum quantity of areas controlled by one system is practically unlimited.

The maximum quantity of relays installed in one system is practically unlimited.
