TLS Series Rev. A2, 8/09

• Introduction

TLS quick float level switches use reed switches as the detection contact and
are designed for liquid level detection. These level switches are designed for
level detection of drainage water and dirty water, such as factory exhaust. They
are also suitable for slurries and high viscosity liquids.

Only one float is needed for ON/OFF control at both upper and lower limits,
and control hysteresis width is easily adjustable on the spot.

Features

• Designed for dirty water containing floating objects and for high viscosity.

• ON/OFF control at both upper and lower limits is achieved with only one
float.

• The simultaneous quick reverse action of the float does not cause switch
chattering.

• Control width (hysteresis between upper and lower limit set points) is
adjustable on the spot.

• Operates even in flowing liquid.

• Long lifetime due to the employment of a reed switch as the contact.

• Easy installation—just hang it down into the liquid.
