Baumer is offering a cost-efficient alternative to vibration level switches that is able to detect the level of viscous or dry substances as well as liquids.

The LBFS level switch is can be mounted in any position and is able to detect high and low levels in tanks or pipelines.

The sensor is unaffected by flow, turbulence, bubbles, foam and suspended solids.

As the sensor head is smooth and very small, even adhesive media does not stick to it.

The sensor’s short response time enables fast filling processes as well as an accurate and reliable keeping of levels.

The level switch can be used for overfill protection, dry running protection of pumps and phase separation in oil-water mixtures.

Fields of application include drinking water, wastewater, filtration, HVAC, hydraulics, oil and gas, bio energy, wood pellets, flour mills, railway transportation or pump systems.

The sensor is encased in a compact, robust and corrosion-resistant stainless-steel housing.

It can be installed and sealed with a Teflon tape and configured on PC via the Flexprogrammer 9701.

Due to its response time of 0.2s, the sensor can offer reliable level detection even in fast filling processes.

The device can be used over a temperature range from -40 up to 115C.

The LBFS is based on frequency sweep technology, whereby a frequency is swept by the transmitter and becomes subject to a phase shift depending on the medium.

When in contact with the medium, which has a different dielectric constant (DC) outside the selected DC range, an electronic switch is triggered.

The high sensitivity over a large sensing range from DC 1.5 up to more than 100 allows the level detection of all kinds of powders, granulates and liquids.

Even difficult substances such as polyamide granulate or paper can be detected.

This technology has no vibrating parts and is not sensitive to changes based on conductivity, temperature or pressure.

Baumer adds that the sensor is suitable for all kinds of applications for which a range of different technology devices would have otherwise been required.
