Switch Level Measurement

Magnetrol’s program of level switches includes a number of different working principles.

Originally the level switches were only mechanical with float or displacer elements and magnetic transfer of the physical movement to a SPDT or DPDT switch mechanism.

These original switches are still supplied, and can further to the direct mounting version be supplied in external flanged or welded chamber with process connections to fit the actual application and clients specifications. Further to the mechanical instruments Magnetrol quote a comprehensive program of electronic level and flow switches. The selection includes tip sensitive capacitive level switches, ultrasonic gap sensors with one or two levels as well thermal dispersion level and flow.

Several of these electronic switches can be quoted in two-wire loop powered units, which instead of a relay function has a mA trip in the output.

Since level switches are very important safety instruments in the process industry, Magnetrol can provide FMEDA reports incl. SIL classification for the majority of its instruments like ATEX certificates are a natural part of the delivery. All instruments of course comply to PED regulation and Non Destructive Examination, material certificates etc. can be ordered as part of the delivery.
