Temperature resistant up to 400°C By Using NK10 – level limiter / float switchBy ALVI
Explosion-hazardous Areas zone 1, zone 2
NK10 is applied into heat and process engineering plants to ensure that the
lowest permissible level is not fallen below. The instrument meets the
requirements of DIN 4574 as limiter.
This series’ instruments are structural tested and have received the DIN registration number /
prototype test mark of DIN CERTCO (company for validation of conformity).
