Product Definition
The Nexisense FST700-204A Capacitive Liquid Level and Temperature Sensor is a high-tech device that integrates liquid level measurement and temperature monitoring functions. It is widely used in various industries, including sanitation, coal mining, petroleum, water conservancy, electricity, meteorology, and transportation. This sensor utilizes capacitive detection principles to monitor real-time changes in liquid levels and temperatures, ensuring safety and efficiency in industrial processes.
Working Principle
The Nexisense FST700-204A sensor employs a capacitive detection principle, utilizing a coaxial container (probe) and an outer shell to form inner and outer electrodes. When liquid enters the container, the change in the liquid's dielectric constant causes a variation in the capacitance between the sensor shell (outer electrode) and the sensing electrode (inner electrode). The sensor converts this change into standard current, voltage, or digital signals while simultaneously measuring the real-time temperature of the medium.
