The ELECTRONSYSTEM MD pressure controllers are
based on a multiple-bellows system which responds linearly to fluid
pressure and which is set to pre-determined pressure values:
"thresholds".
The thresholds can be defined in terms of decreasing pressure or in
terms of increasing pressure. On reaching the pre-set threshold, an
electrical switch is activated, which can:
A. activate processes or protection systems;
B. signal the location of anomalous conditions inside a system;
thus enabling monitoring and diagnostic of pressure of gaseous or,
generally, fluid level. Activating the action starting from a closed
contact instead from an open one enables the self diagnostic of all
circuits interested to the connections.
All the seals are guaranteed with very low temperature too: the gaskets
are not degradable and can't be attacked from substances contained in
the fluid being monitored.
