Harsh operating conditions are part of the challenges faced by the production in the process manufacturing industry. There are many variables to consider when choosing the instrument to measure an aggressive medium.
Here are some guidelines to choosing the right level sensor to cope with aggressive / hazardous medium:
Float Level Switch (Oil) - NIVOSTOP SS2 Series
Float Level Switch (Hazardous) - NIVOSTOP C & EX
Cable Suspended Resistive Level Probe - HE / HS
Hydrostatic Level Transmitter - BAMONIV TPS
Hydrostatic Level Transmitter - MEMPRO
Sludge Level Probe - MUDSENS
Float Level Switch (Oil) - NIVOSTOP SS2 Series
