Detail:
ZK-UZ-C-F series side mounted type magnetic turning column liquid level meter is on-site installation of direct reading liquid level meter and variable transmission unit using high quality stainless steel material, promulgated by the Ministry of chemical industry of magnetic level gauge standard HG/T21584 manufacturing; while providing PTFE lining magnetic turning column liquid level meter, level meter connecting part of the liquid material with PTFE, widely used in all kinds of petrochemical, chemical companies, measurement of any type, any of the concentration of acid, alkali and strong oxidizing agents such as process medium level. The standard 4-20mA current signal is converted into a standard by the circuit.
Is suitable for low temperature to high temperature, vacuum to high pressure and other environment, is the ideal liquid level measurement products in the petroleum, chemical and other industrial sectors. Depending on the location of the vessel, the side and top two forms are provided. According to different working medium, while providing stainless steel and ABS, PP-R engineering plastics three kinds of material, including ABS, PP-R material is also suitable for acid, alkali and other corrosive media.
The characteristics of
To float for the measuring element, driving magnetic turning column display, without energy.
With the upper and lower limit switch output, can realize remote alarm, limit control.
With the transmitter can realize the liquid level far distance indicator, detection and control.

The components and wiring system
1, upper and lower limit switch output
The switch and the converter are composed of a self retaining tongue spring switch and the switch are respectively arranged in the field and the control room, provided by the converter three to the contact switch.
2, the electric remote
The two parts of the measurement unit and the variable delivery unit.
3, explosion-proof
A with explosion-proof, upper, lower limit switch output
The explosion-proof switch is composed of a reed switch and a relay contact, which can provide a pair of normally open or normally closed contacts. Such as users need more contact can be a special design order.
