Zelio level control relays control one or two levels with fill or empty function. The settings
are protected by a sealable cover, control status is indicated by an LED, and they are
DIN rail mountable. RM35LM is designed to control levels of conductive liquid, and
RM35LV is designed to control levels of other materials.
Application examples for RM35LM: Application examples for RM35LV:
•
Detecting pump seal failures
•
Spring, town, industrial and sea water
•
Metallic salt, acid or base solutions
•
Liquid fertilizers
•
Non-concentrated alcohol (<40%)
•
Liquids in the food-processing industry:
milk, beer, coffee, etc.
•
Chemically pure water
•
Fuels, liquid gasses (inflammable)
•
Oil, concentrated alcohol (>40%)
•
Ethylene, glycol, paraffin, varnish and
paints
