The liquid level transduer ruged vertical entry submersible liquid level sensor. It can be suspended in an open tank or attached to the crown of an enclosed tank and used to any depth. The Liquid Level transducer family incorporates the principle of total internal reflection to create a fast, reliable, cost effective solid state sensor. The LLT series are sealed to meet IP67 and have reverse polarity and overvoltage protection. Housed in stainless-steel, the LLT series has long life and is easy to clean. The LLT series terminates using industry standard Quick-connect connectors. Collihigh can provide four models for consumer's applications. All of the transducer's accuracy is 0.25% or greater. Output options are 0-5 VDC, 0-10 VDC, or 4-20 mA.
