Magnetostrictive Level Transmitters
RF Admittance Level Transmitters
RF admittance is a new level control technology developed from capacitive, anti-hanging material, more reliable, more accurate, and more applicable. It is an upgrade of capacitive level technology.
The so-called radio frequency admittance, admittance means the reciprocal of the impedance in electricity, which is composed of resistive components, capacitive components, and inductive components.
And radio frequency is the high frequency radio spectrum, so RF admittance can be understood as using high frequency Radio wave measurement admittance.
Advantages
versatile in temp., pressure, corrosive media
no sticking material at sensor
no interference with steam, foam,...
accurate and reliable
Conductivity Switches
Conductivity level switches are used for checking liquid level of tanks and boilers. They have no movable parts and are used in liquids with solid particles, low density, high viscosity, corrosive, and reagent monitoring applications. Multiple level probes give signal at different levels for high/low alarm.
Two metallic probes of different lengths (one long, one short) are inserted into a tank. The long probe transmits a low voltage, the second shorter probe is cut so the tip is at the switching point. When the probes are in liquid, the current flows across both probes to activate the switch. The AC current can be evaluated with a relay circuit.
Application Areas
lt is an economic and safe solution for air pressure tank applications, water level control of steam boiler condensate tanks, degasifier tanks and other conductive tanks.
