Non-contact Liquid Level Switch

Model : SPM20020S

Initial Weight : 20.00g


Availability: In stock

Intelligent non-contact liquid level sensor (here in after referred to as the liquid level sensor) adopted the advanced signal processing technology and high-speed signal processing chip, broke through the vessel wall thickness, the influence of realized in an airtight container level of real non-contact detection.Liquid level sensor (probe) installed on the outer wall of the container to be tested on the lower part (level of high and low), non-metallic containers without the hole, easy to install, do not affect production.Can realize various toxic substances of high pressure airtight container, strong acid, strong alkali and all kinds of liquid level detection.The material of liquid level sensor for liquid medium and container no special requirements, can be widely used.
