CLW series RF admittance Continuous Level Transmitter (hereinafter referred to as the transmitter), DE is used by the US company's advanced technology, the basic function of the design and production of the level control instrument. Its high reliability and a unique sensor circuit module all imported devices. It uses admittance impedance and capacitance measurement information measured media combined, improve the reliability, stability, sensitivity, and accuracy of long-term measurements, measuring almost any level medium without sensing probe hanging material, temperature, medium density change impacts. It can be widely applied in liquid, solid position in petroleum, chemical, metallurgy, electricity, medicine, food, paper, building materials and other industrial fields, oil-water interface and content analysis of continuous measurements, the transmitter converts the measured level 4-20mADC standard current signal can be used with DDZ-Ⅲ electric instrumentation and DCS distributed control system supporting the use of the process to achieve automatic detection and automatic control.
