Float the structure of thermocouple

Float thermocouple is a commonly used material level meter, measuring accuracy, stable performance, high reliability and convenient maintenance etc advantages, is widely used in many fields. Users had to float the structure of thermocouple know? Engineering is to introduce the specific below, hope that can help users better application products.

balance type

using pulleys and rigging a container in the balance of the external force, such as weight or wind, and in the float link inside the container. When float up and down with the liquid level do drive the rigging, pulley, or weight or a clockwork, through detecting displacement or rotation of the movement in reading level on the outside containers.

this type of thermocouple used in large storage tank is more, common are: buoy thermocouple, steel belt thermocouples, etc.

lever

to set a lever and set the fulcrum in the walls of the vessel where the float is fixed at one end of the lever located on the inside of the container, when float up and down with the liquid level do drive lever located in the container at the other end of the exercise, or turns fulcrum, by detecting the movement of the displacement or rotation level can be read on the outside containers.

this type thermocouple strong ability to resist external force due to its structural characteristics and high reliability, so commonly used or made into liquid level switch on the mobile container. Common are: Marine thermocouple, float switch, etc.

connecting rod type

one connecting rod is set on the upper float, drive the connecting rod synchronous when float up and down movement up and down, and read liquid level in the connecting rod.

this kind of thermocouple is suitable for the liquid level is lower than the personnel operating height ( Such as the underground pool) The level measurement.

the guide bar type

will float to make ring set on a guide rod, float with the liquid level changes do up and down along the guide bar. A permanent magnetic objects inside the float, magnetic sensor inside the guide bar set at the same time, from the magnetic sensor detection and float position to the representative of the corresponding level of high and low electrical signal output.

this type of thermocouple in containers within the medium exists in the better during strenuous exercise, the scene of the only remote transmission signal does not need to liquid level gauge type has the characteristics of simple structure. At the same time are adopt in naming 'float thermocouple' more types.

pipe type

one vertical pipe is set on the outside of the container, up and down through the pipe connected to the container, according to the principle of connecting pipe when the container is memory is liquid, the liquid will enter the vertical pipe, and with the container of liquid surface contour. Then built a float in pipe, the position of the float can reflect the container liquid level.

this type thermocouple due to float setting on the outside of the container, from horizontal movement of the liquid in the container. So good adaptability, and can be more application environment to realize high accuracy of measurement.
