UDK-202 Intelligent Electric Contact Liquid Level Display Controller

Overview

UDK-202A is an intelligent electric contact level measuring instrument developed and produced by our factory, suitable for level measurement and control of boiler steam drums, high-pressure heaters, low-pressure heaters, deaeration evaporators, separators, water tanks, etc. UDK-202B can also be used for liquid level measurement and control of various non-conductive, flammable, explosive, and corrosive media in the petrochemical industry. It is a patented product of our factory and cannot be imitated. This product also solves the problems of scaling, corrosion, leakage, and replacement of spare parts for ordinary electric contact level gauges, as well as the need to adjust water resistance changes. It is a very convenient product for on-site operation and control in power plants and petrochemicals.
The secondary meter adopts high input impedance integrated operational amplifier and DSP technology, which is an intelligent instrument. The display part adopts both analog display and digital display methods simultaneously. In order to eliminate the possibility of false water level caused by water droplets on the electrical contact, the alarm logic control and judgment function is adopted to effectively prevent false water level alarm
