Housing and Switches for the SENSILEVEL.
SENSILEVEL switch devices consist of an AISI 304 stainless steel frame, equipped with a lever, on whose end is mounted a permanent magnet which provides the required energy to operate the switch.
Switch devices can be fitted with electric switches (only one switch with SPDT function, or two switches simultaneously operated with DPDT function) or with a pneumatic shutoff device (3-port valve).
Switch devices are fitted in special housing, available in standard and explosion-proof version and various protection degrees. The widespread use of stainess steel and careful selection of insulating materials for cables and terminal block, make the switch devices also suitable for tropical environment.
As the temperature inside the housing is influenced by the process fluid, there are specific limits for switches use; the table below shows the maximum design temperatures for process fluid, for various types of switches, in different configurations of level switches.
