The WIKA HLS-M Miniature Level Switch is a compact and reliable float-type level switch designed
for horizontal installation in tanks, vessels, and industrial process systems. Manufactured by
WIKA, the HLS-M series is engineered for precise point level detection of
liquids in industrial automation and process control applications. Its miniature design makes it ideal
for installations where space is limited while still delivering dependable switching performance.
The switch operates using a magnetic float mechanism that activates a reed contact when the
liquid reaches the preset switching point. This simple and robust operating principle ensures
high reliability, low maintenance, and long operational life. Constructed with corrosion-resistant
stainless steel materials, the HLS-M level switch is suitable for water, oils, chemicals, coolants,
and various industrial liquids.
Designed for horizontal mounting, the WIKA HLS-M can be installed directly through the side
wall of tanks or containers for accurate high-level or low-level detection. Its compact structure,
rugged design, and easy integration make it widely used in industrial machinery, water treatment
systems, hydraulic equipment, and process automation applications.
