ZY-CDS magnetic sensitive liquid level gauge(LED level gauge)Working principle:
There is a magnetic float inside the main tube of the liquid level gauge. The float is designed according to the specific gravity of the medium. The magnetic steel inside the float is at the same height as the liquid level in the container. The liquid level LED display scale is equipped with a semiconductor magnetic sensor, which is arranged in an orderly manner with the LED light emitting module. The semiconductor magnetic sensor corresponding to the magnetic field is magnetized and triggers the corresponding digital circuit. The LED above the liquid level displays in red, and below the liquid level displays in green. The red displays the vapor phase, and the green displays the liquid phase. The actual liquid level in the container is located at the red green boundary, which is clear at a glance. ZY-CDS magnetic sensitive liquid level gauge(LED level gauge)Product features: 1. Gas red liquid green, with clear luminous display, large observation angle, and long visible distance. It can clearly display the liquid level with red and green light columns, suitable for application in low light places, and more eye-catching for night observation. 2. The body is made of stainless steel, and the liquid level gauge display device does not come into contact with the medium inside the container, so there is no leakage. Suitable for use in Class I, II, and III containers, and absolutely safe and reliable for containers containing flammable, toxic, and corrosive media. 3. It has a large display range and a wide range of applications, suitable for low temperature, medium temperature, and high pressure situations. 4. It can output 4-20mADC standard signals to achieve remote display of liquid levels, centralized monitoring and control of liquid levels in container groups, and can also be equipped with liquid level switches to achieve interlock protection.
ZY-CDS magnetic sensitive liquid level gauge(LED level gauge)Technical parameters:
Nominal pressure: 0.6, 1.0, 1.6, 2.5, 4.0, 6.4, 10.0 MPa
Medium temperature: -40~538oC Medium density: ≥ 0.45g/cm3 Process connection: Various sizes and grades of convex, concave convex, and mortise and tenon flanges; Flange material: carbon steel, stainless steel Flange installation center distance: ordinary type: L=500-5000mm (orders can be negotiated for sizes greater than 5000mm) Display range: equal to the center distance of the flange Sensor material: 304, 316, PP, Fiberglass reinforced plastic, 304 lined with polytetrafluoroethylene Magnetic float material: 304, 316, titanium alloy Display colors: vapor red, liquid green Power supply voltage: AC36V or AC220V Output signal: 4-20mA standard signal Applicable media: water, steam, acid, alkali, oil, ammonia, benzene ZY-CDS magnetic sensitive liquid level gauge(LED level gaugeofInstallation and use: 1. This product must be installed vertically with a maximum deviation of ≤ 3o, connected to the container through a flange 2. There shall be no iron or magnetic substances within a distance of 20cm around the liquid level gauge 3. Connect the sensor to the container being measured, install a DN15 valve at the lower end of the sensor discharge flange, and connect it to the discharge pipeline of the original liquid level gauge 4. Connect the power supply AC220V (or AC36V), and the liquid level gauge should display full red at this time 5. First open the upper valve, then slowly open the lower valve, especially when the level gauge is used on high-pressure pressure vessels (such as power plant boilers), pressure must be slowly injected to prevent the float from suddenly being damaged by pressure, causing the medium to slowly flow into the sensor. Observe the liquid level display and switch from red to green one by one. 6. Liquid level display adjustment: Raise the liquid level of the container to the center, move the display box of this liquid level gauge up and down to match it, move left and right to adjust it to a position that is easy to observe, and then tighten the upper and lower fixing rings to put it into use.
