Solid-state level sensors are more reliable

Edited by the Engineeringtalk editorial team Nov 17, 2006

Ultrasonic liquid level switches are direct replacements for mechanical float type or electro-optic liquid level devices for high and low level alarm, pump protection, auto fill/auto empty operation.

Seniti LL-01 Series liquid level switches are a direct replacement for mechanical float type or electro-optic liquid level devices for high and low level alarm, pump protection, auto fill/auto empty operation using proven ultrasonic technology and solid state surface mount integral electronics.

The LL-01 Series provides reliable operation in virtually any liquid which eliminates the problem of stickiness and failure rate due to finite mechanical life inherent into the mechanical float design.

With fully epoxy sealed electronics, combined with ultrasonic sensing technology, the Seniti LL-01 is designed for years of maintenance free service with mechanical connection 0.25in NPT and 0.5in NPT 316SS sensor construction operating temperature up to 100C to meet a wide spectrum of difficult environmental applications.

Cosense will also customise special versions of the LL-01 Series for OEM applications.

Integral electronics with 5 to 30V DC input power with transient reverse polarity protection.

Different outputs are available such as two wire loop power type, relay output, and source or sink current types.
