RF admittance level transmitter is continuous level measurement products based onthe principle of radio frequency admittance, and is developed on the basis of the tradi-tional capacitance level transmitter.

It is widely used for the continuous measurement in the field of petroleum, chemical industry, metallurgy, medicine, electricity, food, paper and other liquid particles.

And it is suitable for the measurement under high temperature, strong corrosion in narrow space environment.

Radio frequency admittance measurement technology is detecting the change of radio waves through the radio frequency circuit.

When the material level meter sensor is installed inside the container, it forms a capacitance apparatus.

The probe is considered as a plate of capacitor, and the container tank wall is considered as another plate capacitor (container as the insulation material) by measuring changes of capacitance value between two plates due to the change of level, RF admittance level transmitter can measure the material level.

RF admittance level transmitter has high stability, high sensitivity, wide applicable field, simple calibration, no need for maintenance, and is suitable for both liquid and solid material.

The instrument body must be reliable grounding and installed steadily to avoid RF rod or cable shaking.

HCCK Factory Direct 4–20mA High Precision

HCCK – Hebei Huachuang M&C Technology Co., Ltd.

Looking for a reliable, high-accuracy RF admittance level transmitter for demanding industrial applications?

The HCDN-503 RF Admittance Level Transmitter from Hebei Huachuang M&C Technology Co., Ltd. (HCCK) is engineered to deliver stable, continuous level measurement for liquids, powders, bulk solids, slurry, and corrosive materials.

Designed with advanced RF admittance technology, the HCDN-503 ensures accurate 4–20mA output, exceptional anti-coating performance, and long-term operational stability — even in harsh process conditions.

The HCDN-503 is developed for industries that demand:

  • ✅ Continuous and precise level monitoring

  • ✅ Excellent resistance to material buildup

  • ✅ Stable performance in high temperature & pressure

  • ✅ Strong anti-electromagnetic interference

  • ✅ Long service life with minimal maintenance

  • ✅ Seamless integration with PLC/DCS systems

If your process requires dependable level control without frequent recalibration, the HCDN-503 is the ideal solution.

RF admittance is an enhanced capacitive measurement technology that compensates for material coating and dielectric changes. Unlike conventional capacitance transmitters, it uses a guard electrode circuit to distinguish between actual material level and probe buildup.
