Level sensor LI for point level detection and leakage monitoring
Reliable alternative for float switches
The LI level sensor is perfectly suited for the detection of level and leakage. Thanks to the capacitive measurement technology, the sensor has no moving parts. Malfunctioning caused by deposits on the mechanical parts is thus excluded, saving maintenance costs and time.
Plug & play point level switch with digital communication
The basic settings on delivery are suitable for use in oils or water, so that a plug & play installation can be carried out in these cases. In addition, the sensor can be adapted as required via IO-Link. The sensor also detects the temperature of the medium and transmits it digitally via IO-Link.
WHG approval
The versions of the LI21x series are approved to DIBt and have an approval according to the German Federal Water Act (WHG). The law serves to protect surface water, groundwater and coastal water. Especially when it comes to the storage of substances hazardous to water, the tanks and the sensors installed on them must have WHG approval.
The right choice for good reasons
Two different media can be detected -Reliable product detection, differentiation between oil and water
The sensor is maintenance-free, as it has no moving parts
One sensor – two measuring parameters:The LI offers level measurement with integrated temperature monitoring
Adjustment and setting can be carried out quickly and easily via inductive teach buttonPoint level monitoring of cooling lubricant, e.g. use as overflow prevention
Goal
- Simple and reliable point level monitoring, e.g. use as overflow prevention
Advantages
- Temperature and level monitoring for increased transparency in your application
- Can be used over a wide temperature range
- Free of mechanical parts – minimum maintenance required
- Easy setting via integrated inductive pushbutton or via software, e.g. moneo
Point level monitoring of hydraulic oil
Goal
- Easy and reliable point level monitoring of hydraulic oil
Advantages
- Temperature and level monitoring for increased transparency in your application
- Reliable monitoring thanks to capacitive measurement technology
- Free of mechanical parts – minimum maintenance required
- Clearly visible indication of the switching status
Replacement of float switches
Advantages
- The LI has no moving parts
- no sticking or jamming
- reduced maintenance complexity
- increased machine uptime
- Works reliably even in the case of soiling and foaming
- Flexible installation position
The LI is available in four different lengths:
| Without WHG approval | With WHG approval |
|---|---|
| LI5131 (132 mm) | LI2131 (132 mm) |
| LI5132 (273 mm) | LI2132 (273 mm) |
| LI5133 (481 mm) | LI2133 (481 mm) |
| LI5134 (737 mm) |
Advantages with IO-Link
- Plug & play thanks to digital communication
The basic settings on delivery are suitable for use in water with the LI513x and for use in oil with the LI213x. In these cases, a plug & play installation can be carried out. In addition, the sensor can be adapted as required via IO-Link - One sensor – two measuring parameters
In addition to the level, the sensor detects the temperature of the medium and transmits it digitally via IO-Link - Transparent processes
Medium changes are accurately detected, allowing early maintenance measures to be taken - Flexible
Free configuration of the switching outputs
