CS3753C Electrical Conductivity Sensor 4-20ma

Short Description:

electrode type liquid level meter uses the electrical conductivity of materials to measure high and low liquid levels. It can also be used for liquids and wet solids with weak electrical conductivity. The principle of the boiler electric contact level meter is to measure the water level according to the different conductivity of steam and water. The electric contact water level meter is composed of a water level measuring container, an electrode, an electrode core, a water level display lamp and a power supply. The electrode is mounted on a water level container to form an electrode water level transmitter. The electrode core is insulated from the water level measuring container. Because the conductivity of water is large and the resistance is small, when the contact is flooded with water, the short circuit between the electrode core and the container shell, the corresponding water level display light is on, reflecting the water level in the drum. The electrode in the steam is small because the conductivity of the steam is small and the resistance is large, so the circuit is blocked, that is, the water level display lamp is not bright. Therefore, a bright display light can be used to reflect the level of the water level.
