After the first copper wire section and the second copper wire section are welded on the inserting piece, the insulating sleeve is installed and then welding is carried out; by applying the principle of absorbing and releasing a reed switch and a magnet, the sensor is arranged in an isolating hole of a liquid tank, and the floater is directly arranged in the liquid tank, so that the sensor is not directly contacted with liquid, and can send out an alarm signal when the liquid level reaches a warning line in place, thereby ensuring the performance stability of the sensor and prolonging the service life of the sensor; epoxy resin is poured into the shell 10 to isolate the internal electrical connection from the external environment.
Description
Technical Field
The utility model relates to a level sensor, in particular to non-contact level sensor.
Background
A level sensor (static pressure level gauge/level transmitter/level sensor) is a type of pressure sensor that measures the liquid level. The static pressure input type liquid level transmitter (liquid level meter) is based on the principle that the static pressure of a measured liquid is proportional to the height of the liquid, adopts a foreign advanced isolation type diffused silicon sensitive element or a ceramic capacitance pressure sensitive sensor to convert the static pressure into an electric signal, and converts the electric signal into a standard electric signal (generally 4-20 mA/1-5 VDC) through temperature compensation and linear correction.
The liquid level sensor is widely used in the fields of industrial production, industrial manufacturing and the like, and the existing liquid level sensor needs to be in direct contact with liquid when in use, so that the stability is poor, and the service life is shortened; and the isolation from the external environment is not tight, which is easy to cause damage risk to the sensor.
