ES 2001, Resistive amplifier relay for level control
- For all electrical conductive liquids
- Dimensions: 22.5 mm width, rail DIN mounting
- Adjustable sensitivity and timer
- Selection of action mode
- Functions:
On /Off level controller between 2 rods
Level regulation between 3 rods

The resistive amplifier relay for level control ES 2001 works with the electrical conductivity property of the liquid, detecting the opening or closing circuit between two electrodes. A complete range of probes and rods are pecially
designed to answer to all type of applications.
The sensibility is adjusted in relation to the liquid conductivity from 1 to 150 kOhm. The hysteresis between On/Off relay switching is about 10% of sensibility; this, is, to avoid false alarms originated by smog, foam or condensation of vapours. With both timers, it is easy to adjust the level detection or level regulation even if the fluid surface is moving (small wave effect).
To use with:
- Reed contact, models included in BRK60, BW60, CNL, MNR6, MNR7 etc.
- Flow switch, such as ZE951 (IDP – PDP), CDP etc.
For level control of electrically conductive liquid media:
- Minimal or maximal levels.
- Dosing, flow detection and alarm, pump control, solenoid valve control, fluid detection in a pipe.
With appropriate electrodes for use as limit transducer in:
- Water, wastewater
- Acids, lye, brines, etc.
It is necessary to have one relay ES2001 for each detection level.
