    The medical float switch is a dedicated model within SAMOTEY’s float-type level switch series. Built upon the company’s core float-based level monitoring technology, it serves as a specialised sensing solution for level detection applications in the medical sector. Designed to meet the diverse level monitoring requirements of medical instruments and equipment, it provides accurate and reliable level sensing and switching signals for medical diagnostics, medical fluid control and other related processes.


     As a specialised application within the company’s float-type level switch series, the medical float switch complements ultrasonic level sensors (contact/non-contact single-point level sensors), collectively covering level monitoring requirements across different installation methods and operating conditions within the medical sector. Furthermore, they can be customised to suit the specific usage scenarios of the customer’s medical equipment, container specifications, and level detection thresholds, thereby providing liquid level sensing solutions tailored to practical medical applications. 


    This product offers a dedicated selection guide for medical applications, allowing customers to match specific models to the actual requirements of their medical equipment, such as fluid type, installation space and liquid level control accuracy. Furthermore, the company can develop optimal customised design solutions for medical float switches based on equipment samples and operating parameters provided by the customer, thereby meeting the medical sector’s core requirements for high precision, high reliability and hygiene in sensing products.
