Safe without a float

Product catalog summary
Overview: The document describes the LI level sensor, a maintenance-free device used for point level and leakage monitoring without a float. It is approved for overflow prevention and leakage detection according to the German Federal Water Act (WHG).
Specifications: The sensor features two switching outputs that can be configured for temperature and level detection. It operates on a voltage range of 9.6 to 35 V DC and supports medium temperatures from -25 to 85°C. The process connection is 16 mm in diameter, and it has a tank pressure rating of 0.5 bar with an IP69K protection rating.
Features: The sensor is designed for easy setup and digital communication, with factory settings for specific media types (oils and aqueous media). It can be adjusted for other media using an inductive teach button and IO-Link technology. The sensor also measures and transmits medium temperature via IO-Link.
Applications: The LI level sensor is suitable for overflow prevention in supply tanks for coolant emulsion and leakage monitoring in hydraulic power packs. It serves as a smart alternative to traditional float switches.
Technical Data: The document provides order numbers for different probe lengths and mentions the availability of an IO-Link interface for parameter setting using moneo|configureSA software. It also highlights the capability to transmit sensor data to IT and PLC levels.
Additional Information: For further technical details, the document refers to the website ifm.com/fs/LI2131. The document reserves the right to make technical alterations without prior notice as of May 2023.

Probe length [mm] With WHG approval Order no. Without WHG approval Order no. Smart alternative for float switches With the LI level sensor, you can reliably detect leakages and point levels on a permanent basis. The capacitive measuring system has no moving parts. Malfunction or maintenance measures due to deposits on the mechanical parts is therefore eliminated. Thanks to the WHG approval, you can also comply with the legal requirements in the environment of substances that are hazardous to water. Easy set-up, digital communication The sensors are factory-set for specific media (LI21xx: oils,...
