The SAMOTEY float-type level switch series represents the company’s core sensing products for level monitoring. As the flagship product line within the company’s four core technological fields, it provides reliable sensing solutions for level detection applications across industrial automation, healthcare, white goods, and environmental monitoring instrumentation.
The float-type level switch series complements the company’s ultrasonic level sensors (contact-type single-point level sensors and non-contact-type point level sensors), covering a wide range of level monitoring scenarios with varying installation methods and detection requirements. Among these, the ultrasonic contact-type single-point level sensor (ST101 series) is a miniature level switch that utilises ultrasonic technology combined with compact electronics to enhance level detection performance in aerated liquids. Designed for fixed installation within machinery, it is available in both standard and customised versions, working in conjunction with the float-type level switch to meet diverse level detection requirements.
