Cape-11A Standard Type

● Excellent versatility, it can be widely used in the measurement of fly ash, solid granular and adhesive materials.

● Has external dual color LED indicator, by rotating the header relatively to the process fitting makes LED indicator convenient for remote observation.

● Modular design with high reliability. Easy installation, no calibration required.

● Passed through reliable tests and received certifications by the third party.

● Superior quality but cheaper price.


  • Cape-11A Standard Type RF Admittance Level Switch can measure capacitance as well as impedance between the probe and vessel, it is an ideal instrumentation to measure dusts and coal ashes. The probe is not affected by adhesive materials, the strong versatility of Cape-11A making it work efficiently in difficult applications. In addition, Cape-11A uses modular design, the installation and maintenance are simple, and it is equipped with external LED lights for remote observation.


  • Cape-11 RF Admittance Level Switch series use probe to sense the change of capacitive reactance and impedance between the probe and the vessel while detecting the material level. Within the electronic unit, the measurement electrode and the reactance of empty vessel together form a balanced bridge circuit and generate a stable oscillation signal. When the level rises and measured medium covers the measurement electrode, the reactance between measurement electrode and vessel wall changes, which causes imbalance of the bridge circuit, and stops generating the oscillation signal. This change will be detected by the post-circuit, and then output an alarm signal. Meanwhile, the oscillation signal works as a radio frequency signal that is applied to measurement electrode but also goes through the 1: 1 voltage-follower and then sends to shield pole. The RF signals of measurement electrode and shield pole have the same electric potential, phase, and frequency, but they are isolated and independent to each other. When a material adhere to the probe, there is no electric potential difference between measurement electrode and shield pole, so the form of electrical isolation ensures the signal change of shield pole has no effect on the detection, thus the reactance change of measurement electrode can only decided by the measured material between measurement electrode and vessel, which make hanging of the probe has no effect on the detection.
