RNW Electronic Level Control Relays
The RNW, WEG level control relay, is an electronic control device that allows monitoring and automatic setting of level of conductive (non-explosive) liquids by means of submerged electrodes. It has front selector that allows adjusting the electronic circuit to the resistivity of the liquid.
Description
Designed in accordance with international standards, the RNW level control relays have front selector that allows setting the electronic circuit to the resistivity of the liquid.
Main Characteristics
- Monitoring and automatic level setting of electric current conducting liquids
- Filling (EN) and emptying (ES) function
- Sensitiveness setting by means of external selectors
- 2 types of accessory electrodes
Applications
- Protection against dry run
- Protection against overflow of the filling tank
- Activation of solenoids, audible or light alarms
- Process automation in general
