Solution de multiplexage MVS
MVS
MVS 2M est un système multicanal permettant de distribuer deux, trois ou quatre canaux de fluides et de signaux à un système de surveillance des gaz (GMS).
Sa fonction est de relier le système de surveillance de gaz (GMS) aux systèmes de prélèvement de gaz et de gaz étalon, cela permet la fonction de redondance.
Disponible en 2 versions:
- MVS 2M chauffé, à utiliser avec le système d’échantillonnage HOFI et les moniteurs de gaz MIR 9000H / MIR FT / Graphite 52 M
- MVS 2M non chauffé, à utiliser avec le système d’échantillonnage SEC et les moniteurs MIR 9000 / MIR 9000CLD / MIR IS
For stacks, the sampling is carried out using the HOFI boxes (MVS 2M – heated version) or the SEC probes (MVS 2M – not-heated version). Other sampling systems are possible on request. The redundancy functions are only ensured for the sampling boxes, DTP (flow-temperature-pressure) function included. All other measurements (dust, mercury, etc.) are not taken into account by the MVS 2M.
- Data communication and control functions are ensured by Ethernet, serial link or dry contact
- No influence from the pressure
- Back-up of RAM memorized data and real time clock
- Interactive menu-driven software with LCD display allowing ease of operation
- All the ENVEA’s gas sampling systems can be used with dry or heated MVS multiplexing solutions (2 to 4 channels)
- Over 1,000 installations worldwide, covering many applications and industries
- Available in 2 versions:
- MVS 2M heated, to be used with HOFI sampling system and MIR 9000H / MIR FT / Graphite 52 M gas monitors
- MVS 2M non-heated, to be used with SEC sampling system and MIR 9000 / MIR 9000CLD / MIR IS monitors

MVS 2M supplies GMS with measurement gas exclusively through one channel, or sequentially through two, three or four channels.
This equipment is slave of the Central Control Desk (PCC), even if it is possible to manually control MVS 2M from LCD screen mounted on the front panel.
