Changzhou City, Xiao source Machinery Co., Ltd. specializes in the production level gauge and the gauge used accessories. The magnetic level gauge used sensors, liquid level, namely 4-20mA output signal, radar level gauge, is to level changes in the container can be displayed on the control room computer equipment, greatly facilitates the site operation. 4 ~ 20mA typical application products is sensing and measurement applications. In the industrial field there are many types of sensors can be converted into a current signal of 4 ~ 20mA, TI has some of the transmitter chip is very convenient for RTD and the bridge. Because TI transmitter circuit chip containing the common features such as voltage excitation source, current excitation current, voltage regulator circuit, instrumentation amplifiers, level gauge conditions of use, so you can easily put signals into many sensor is 4 ~ 20mA signal. So why not choose 4-20mA 0-20mA it? To reduce the complexity of the wiring, the sensor 2-wire more than a simple multi-line, 2-line only to transmit signals, gauge accessories, but also to power the sensor, so the designers from theft 4mA current to the sensor amplification circuitry, Such a standard 4-20mA determined. Changzhou City, Xiao source Machinery Co., Ltd. of magnetic float level gauge an overview UHZ-25-type magnetic sub-level gauge and UHZ-27 type top mounted float level gauge can be configured to remote level transmitter, in order to achieve the level of signal remote digital / analog display. Second, the structural principles of MY type genus analog level transmitter, a two-part liquid level sensor and a signal converter. By the level sensor installed in the φ20 stainless steel protection tube several reed and a number of resistors, protective tube secured to the measuring tube (tube body) outer surface; a signal converter consists of electronic modules, sensors placed in the top or bottom of proof junction box Third, the main technical parameters 1, Range: determined by measuring range H; 2, error: ± 10mm; 3, the output signal: 4 ~ 20mA.DC (two-wire); 4, load resistance: ≤550Ω; 5, Supply voltage: 24V.DC; 6, and outlet: M20 × 1.5 (within); 7, ambient temperature: -40 ~ + 60 ℃; 8, explosion-proof grade: dⅡBT1-4; 9, shell protection grade: IP65. Third, the characteristics of magnetic levitation level gauge magnetic levitation level gauge has a simple structure, easy to use, stable performance, long life, easy to install and maintain. Fourth, the application of magnetic levitation level gauge main widely used in petroleum processing, food processing, chemical, water treatment, pharmaceutical, power, paper making, metallurgy, shipbuilding and boiler level measurement.
