LL10-1AC01

LL-10 Series – Relay Version  A direct replacement for mechanical float type liquid level devices  Proven ultrasonic technology  Solid state integral electronics  Designed for years of maintenance-free service DESCRIPTION The Solid State Float™ LL-10 series liquid level switch is a direct replacement for mechanical float type liquid level devices. It employs proven ultrasonic technology and solid state integral electronics. The Solid State Float™ provides reliable operation in virtually any liquid and eliminates failures due to finite mechanical life inherent in the mechanical float design. With fully epoxy sealed electronics, combined with ultrasonic sensing technology, Solid State Float™ is designed for years of maintenance-free service. Measurement Specialties, Inc. can also customize special versions of the LL-10 Series.
