    - The block has intended for the bleeding air through metering devices of settings UDA-1AB, UDG-1B and UDGB-01Т (production of scientific production enterprise "DOSA", Russia). It is working in unison (pneumatic tandem connection of settings UDA-1AB, UDG-1B and the block).
    - The block does controlled of a band filter dirtiness of a setting UDA-1AB and initiates change of a frame by band filter of a setting UDA-1AB.
    - The block does controlled of a band filter integrity of a setting UDA-1AB and excites issue of an emergency signal by setting UDA-1AB at the damage of a band filter.

    Sampling of air could be carry out as immediately from an atmosphere of industrial premises, and at the help isokinetic sonde from vent systems of Nuclear Power Plants (trier OS-1700 ("AMETЕК", USA)).

  • Pump block BN-01-01

    Advantages:

    blocks provide a continuous flow of air through the measuring instruments and devices. The flow can be changed using the tuning parameters;
    blocks produce diagnostics of integrated devices;
    blocks indicate the pressure difference on the measuring instruments and devices;
    equipped with two pumps operating on the principle of 'hot' backup (in case of failure of the main pump, switching to a backup pump takes place without human intervention);
    provide PID-control flow of pumped air depending on the flow of the original environment from which you are sampling (pumping);
    supervise pressure difference on analytical filter (measuring instruments),provides diagnosis, embedded devices, the external flow and temperature sensor.

    Pump block BN-01-04

    Block designed for continuous pumping of air sampling systems (for devices that produce the measurement of volumetric activity of aerosols, IRG and volume activity iodine). Block produces control the dilution of its input and supports a vacuum within the prescribed limits. In case of impossibility maintain the vacuum at the entrance to the block within the specified limits unit produces an automatic transition to work from a backup pump.

    Block to ensure uninterrupted operation is composed of two pumps. Depending on the settings in case of failure of one (main) pump pumping unit automatically turns on second (redundant) pump. Block the pump in the operation provides continuous automatic operation check of the frequency converter and pumps (main and backup). To protect against unauthorized access, block has a special key to open the control cabinet door.

    Functionally, the unit consists of the following components:
    - two vacuum pumps VT4.40;
    - measuring unit BOI-12-01;
    - control cabinet;
    - gauge DV2005 (-1 to 0).
