Original E+H level gauge * for sale
The working principle of the magnetostrictive type of E+H level gauge and the electronic components on the upper end of the probe? Generate a low-voltage current pulse, start timing, and generate a magnetic field that propagates downward along the magnetostrictive line. The float moves up and down along the measuring rod as the liquid level changes. There is a magnet inside the float, which also generates a magnetic field. When the two magnetic fields meet, the magnetostrictive line twists to form a torsional stress wave pulse. The pulse velocity is known, and the calculation of the pulse propagation time corresponds to the accurate change in liquid level. (Current travels at the speed of light, so its propagation time can be ignored compared to force wave time) Can the highest accuracy reach 1mm? Analysis of advantages and disadvantages? The magnetostrictive liquid level has high accuracy, and the E+H liquid level gauge can measure the oil-water interface. However, due to its contact measurement method and high installation and maintenance requirements, it is not widely used in the market.

The contact measurement of E+H level gauge started from the steel strip float level gauge and evolved into various modern instruments such as servo type, magnetostrictive type, etc. The earliest level gauges are now facing updates and replacements. The principle is that the float floats on the surface of the medium under buoyancy, and reads the liquid level value on the steel strip with a scale through a variable speed gear. When the liquid level rises or falls, the force balance is disrupted, and the float also rises and falls, driving the steel strip to run. The theoretical accuracy of the E+H level gauge is around 2-3mm, which is complex to install and has low reliability. Due to the large number of mechanical components, it is easy for the steel strip to get stuck and not move. Fiber optic technology digitizes the liquid level of steel strips by reading it out through an optical encoder.

Install the probe of the E+H level gauge at the bottom of the tested container, ensuring it is tightly attached to the container wall. Connect the probe lead to the instrument signal interface and turn on the power. Before use, check if there is any looseness in the front and back covers of the instrument housing, and use tools to tighten the front and back covers. After turning on, the instrument will automatically complete the self check function and enter the measurement display state, achieving real-time continuous measurement. Users can directly read the liquid level height value inside the measured container from the LCD screen through the instrument observation window. When the E+H level gauge instrument leads need to be split or rewired, an explosion-proof junction box (with an explosion-proof certificate and an Ex mark on the junction box) must be used. When there are redundant outlets in the junction box, it is necessary to use sealing components of the explosion-proof type * of the junction box to ensure its explosion-proof performance.
