The IFM LMT100 is a capacitive point level sensor designed for hygienic and process-level monitoring applications. It has an 11 mm probe and a G1/2 sealing-cone process connection for compact installation. Two configurable digital outputs provide flexible level switching, while IO-Link enables advanced parameterisation and diagnostics. The sensor is factory preset for water-based media and can detect liquids, viscous media, and suitable process materials. Its stainless-steel construction, PEEK sensing tip, and IP68/IP69K protection provide reliable operation in demanding environments.

The LMT100 provides reliable point level detection using capacitive sensing technology. Its short 11 mm probe makes it suitable for compact tanks, vessels, and pipe installations. The sensor is factory configured for water-based media for convenient commissioning. The sensing parameters can also be adapted through IO-Link when required. This provides a practical solution for detecting defined fill or empty conditions.
The LMT100 features two digital outputs that can be configured for normally open or normally closed operation. PNP/NPN output configuration provides compatibility with different control architectures. One output also supports IO-Link and teach functionality. The response time is less than 0.5 seconds for rapid level detection. This flexibility allows the sensor to support automated filling, draining, and protection systems.
The sensor uses stainless steel 316L together with a PEEK sensing tip and FKM sealing materials. The wetted sensing surface has a smooth finish of Ra <0.8 µm / Rz 4 µm. The G1/2 sealing-cone connection supports hygienic process installation. IP68 and IP69K protection help protect the sensor against moisture and intensive cleaning. Gold-plated M12 contacts provide a durable electrical interface.

The LMT100 should be installed at the desired point level using an appropriate G1/2 sealing-cone connection. The sensing tip should remain correctly positioned within the monitored medium. Installation should avoid mechanical damage to the PEEK measuring tip. IO-Link can be used to configure and verify sensor parameters after installation. Regular inspection of the connection and sensing area helps maintain dependable operation.
The compact probe makes the LMT100 suitable for installations where available insertion space is limited. Its hygienic construction supports applications involving water-based liquids and process media. The sensor can be integrated directly with PLC systems through its switching outputs. IO-Link adds digital parameterisation, identification, and process-data functionality. This makes the LMT100 suitable for modern automated process equipment.
