◇ Overview UHZ type magnetic sub-level gauge for measuring element is a float, passing through the magnetic coupling to change the level of the indicator, the indicator can clearly indicate the level of height, level gauge with level alarm and level transmitters. Upper and lower control limits alarm warning level can be achieved, level transmitter can be converted into a change in the level of 4-20mADC current signal. Level gauge for large storage tanks, tank and other containers of various level measurement and control. Level meter alarm transmitter with explosion-proof function, it applies to all kinds of corrosive, toxic, flammable, explosive and other occasions. ◇ works UHZ type magnetic sub-divided into basic level gauge, liquid level alarm and level transmitters three parts. Level gauge is based on Archimedes' principle and the principle of magnetic coupling made of, when moving the float measuring tube up and down with the level of change, through magnetic coupling, drive inside flap display rotation, clear indicator solution bit height, so as to achieve the purpose of measuring the liquid level. Level alarm is based on the characteristics of the magnet, driven reed inside alarm, it is closed or open, so that the alarm setpoint by gauge action, and achieve the level of alarm and control limits. There are two types of level transmitter for users to choose: one is from the basic model of the magnet pull the float transmitter reed, to convert it into a change in the level of DC4-20mA standard current signal, remote control or display. Another is the company's original UHA coupler level transmitter, when the float with the level changes, through magnetic coupling principle, driven magnetic components within the transmitter action, then by converting circuit to convert liquid level the corresponding standard 4-20mA current value.
