The invention discloses a liquid-level sensor for an etching liquid cycle regeneration system. The liquid-level sensor comprises a rod that is of a cylindrical structure with hollow inside. One end of the rod is of a sensing rod, a reed switch is arranged inside the sensing rod, a retainer ring and a positioning pin are respectively arranged at two ends of the sensing rod and a magnetic float is sleeved on the sensing rod. A lower stop and an upper stop are arranged on the right side of the positioning pin on the rod, a groove is arranged in the rod between the lower stop and the upper stop, a through hole communicated with the hollow inside of the rod is formed at the end, of the outside of the upper stop, of the rod, and a sensing wire electrically connected with the reed switch extends out of the through hole. The liquid-level sensor for etching liquid cycle regeneration system is adaptable to liquid containers in any size and optional liquid levels, can be fixed to required positions, and has good stability and high practicability.
Description
Technical field [0001] The present invention involves a liquid level sensor, which specifically refers to a liquid level sensor for etching liquid circulation regeneration system. Background technique [0002] As a Hall sensor that measures the liquid level, the liquid level sensor is based on the principle of Hall components, and the liquid level measurement is achieved by converting magnetic induction intensity into a electrical signal, and the liquid level sensor is now available.It has been widely used in liquid level measurement of various mediums and industries of petrochemical, metallurgical, electricity, pharmaceutical, pharmaceutical, pharmaceuticals, water supply and drainage, and environmental protection.The exquisite structure, simple adjustment and flexible installation methods provide great convenience for users to easily use. [0003] Most of the liquid level sensors today use a overall rod body to cover the floating block and limit it with limited blocks. When use...
