4. Dry reed level sensor (liquid level switch)

Float liquid level switch belongs to a kind of dry reed float liquid level switch. Float ball floats up and down with the liquid level, when floats to the designated position, the magnetic reed switch in the rod induces the magnetic field and outputs the signal (normally open or closed).

1) Product features

A. No standby power consumption, normally open, normally closed, single pole double throw C type optional

B. Multiple detection methods, single point, double point, multi-point detection.

C. Simple structure, stable performance and high cost performance are the most widely used liquid level sensor (liquid level switch) at present.

2) Dry reed type liquid level sensor application field

A. Sewage treatment, agricultural pond

B. Coffee machines, water dispensers, dehumidifiers, humidifiers, washing machines and other household appliances

C. Auto radiator
