Overview
Product Overview: The liquid level transmitter is composed of high-performance diffused silicon piezoresistive pressure sensors and PT100 as measuring elements. It accurately measures the static pressure of the liquid proportional to the depth of the liquid level. The pressure and temperature signals are processed by a new ASCI amplification circuit and converted into standard (current or voltage) signals for output, establishing a linear correspondence between the output signal and the depth and temperature of the liquid, and achieving measurement of the depth and temperature of the liquid

Product Overview
The liquid level transmitter uses high-performance diffused silicon piezoresistive pressure sensors and PT100 as measuring elements to accurately measure the hydrostatic pressure of the liquid proportional to the depth of the liquid level. The pressure and temperature signals are processed by a new ASCI amplification circuit and converted into standard (current or voltage) signals for output, establishing a linear correspondence between the output signal and the depth and temperature of the liquid, and achieving measurement of the depth and temperature of the liquid.
Product Features
■Equipped with dual output signals for liquid level and temperature
■Suitable for measuring liquid level and temperature
■High reliability and stability
■Compact structure and easy installation
■Simply pour in the liquid and it can be used
