CSPPM electronic liquid level transmitters are of three types, namely, immersion level transmitter, ultrasonic level transmitter, and capacitive level transmitter, which can be selected according to different working conditions.
Based on the principle that the static pressure of the liquid is proportional to the height of the liquid, the immersion level transmitter uses diffused silicon sensitive elements, which are then converted into standard electrical signals through compensation and amplification by a dedicated circuit. It is suitable for the liquid level measurement of various media in systems and industries such as petrochemicals, metallurgy, electricity, pharmaceuticals, water supply and drainage, and environmental protection.
The principle of the ultrasonic level transmitter is to calculate the distance from the sensor to the surface of the measured liquid based on the time between the emission and reception of the sound wave. It is characterized by non-contact measurement and is widely used in the measurement of the height of various liquids and solid materials.
The capacitive level transmitter uses the change of capacitance to measure the liquid level of the medium in the container. The change in the height of the liquid affects the capacitance value of the electrode in the level transmitter, which is converted into a standard electrical signal through the circuit. It is used in various scenarios such as oil tank level measurement, solution level measurement in the chemical industry, and boiler water level
