ENS 3000 Electronic Level Switches with Integrated Display with IO-Link
The ENS 3000 with IO-Link communication interface is an electronic level switch with integrated display. The instrument has a switching output and additional output that can be configured as switching or analog (4 .. 20 mA or 0 .. 10 V). The ENS 3000 can be used not only for oil but also for water and is available with or without temperature sensor.
Compared with the standard version, the IO-Link interface enables bidirectional communication between the device and the control. Parameterization and cyclical transmission of process and service data is therefore possible.
The level switch series ENS 3000 with communication interface IO-Link according to specification V1.1 has been specially designed to connect sensors in automation systems. Typical fields of application are machine tools, handling and assembly automation, intralogistics or the packaging industry.
Special features:
- IO-Link interface
- 1 PNP transistor output
- Additional signal output, can be configured as PNP transistor switching output or analog output
- Selectable for use with oil or water
- 4-digit display
- Display rotates in two axes for optimal alignment
Setting options:
All terms and symbols used for setting the ENS 3000 as well as the menu structure comply with the specifications in the VDMA Standard for level switches.
Setting ranges of the switching outputs:
| Probe length in inches | Meas. range in inches | Lower limit of RP / FL in inches | Upper limit of SP / FH in inches |
| 9.80 | 6.70 | 0.05 / 0.10 | 6.70 / 6.60 |
| 16.20 | 11.40 | 0.10 / 0.20 | 11.40 / 11.25 |
| 20.50 | 15.35 | 0.15 / 0.25 | 15.35 / 15.15 |
| 28.7 | 23.20 | 0.25 / 0.35 | 23.20 / 22.85 |
| Probe length in inches | Min. difference betw. RP & SP and FL & FH in inches | Increment in inches |
| 9.80 | 0.05 / 0.10 | 0.05 |
| 16.20 | 0.10 / 0.20 | 0.05 |
| 20.50 | 0.15 / 0.25 | 0.05 |
| 28.7 | 0.25 / 0.35 | 0.05 |
All ranges given in the table are adjustable by the increments shown.
SP = switch point
RP = switch-back point
FL = level window lower value
FH = level window upper value
Additional functions:
- Switching mode of the switching outputs adjustable (switching point function or window function)
- Switching direction of the switching outputs adjustable (N/C or N/O function)
- Switching outputs can be assigned to fluid level or temperature, as required
- Switch-on and switch-off delay adjustable from 0.00 .. 9999 seconds
- Display can be adjusted (actual fluid level, actual temperature, peak values, switching point 1, 2, 3, 4 or display off)
- Analog output can be assigned to fluid level or temperature as required (depending on model)
