Level sensors are devices used to detect and monitor the level of liquids or bulk solids in tanks, silos, pipelines, and open containers. They play a critical role in industrial automation, process control, and safety monitoring by providing accurate level information for a wide range of applications, including water treatment, chemical processing, food and beverage production, oil and gas extraction, and manufacturing.
SUCH provides a comprehensive selection of level sensors designed to meet diverse process conditions, such as high temperatures, pressures, corrosive media, and varying dielectric properties.
- Capacitive Level Sensor: Capacitive level sensors measure level changes based on variations in capacitance caused by different media. They are suitable for liquids, powders, and granular materials, especially in applications requiring high sensitivity and compact design.
- Radar Level Sensor: Radar level sensors use microwave signals to measure the distance to the material surface. They offer high accuracy and reliability under harsh conditions, including high temperature, high pressure, dust, and vapor, making them ideal for industrial and outdoor applications.
- Ultrasonic Level Sensor: Ultrasonic level sensors emit high-frequency sound waves and calculate the level based on the echo time. They are commonly used for non-contact level measurement of liquids and solids in open or closed tanks, providing easy installation and cost-effective performance.
In addition, SUCH also offers a wide range of level sensing solutions designed for both liquid and solid level measurement. The product includes submersible level sensors for continuous liquid level monitoring, hydrostatic level sensors for pressure-based level measurement, and magnetostrictive level sensor for high-precision applications.
For level point detection and process control, we provide various level switch, including tuning fork level switch, vibrating rod level switch, paddle level switch, electrode level sensor, RF admittance level switch, and photoelectric level sensor. These devices are suitable for diverse media such as water, oil, chemicals, powders, granules, and bulk solids, and can operate reliably under challenging conditions involving high temperature, pressure, dust, or corrosive environments.
