Principles of Good Measurement - Capacitance Sensor     

Measuring principle - Capacitance Sensor

The proven capacitive measuring principle is one of the most common measuring principles for level measurement in the industrial measurement technology. Sensor and vessel form the two electrodes of a capacitor. A capacitance change caused by…

Principles of Good Measurement: Ultrasonic Level Transmitters     

Measurement Principle of Ultrasonic Level Transmitters

Short ultrasonic impulses in to range of 10 to 70 kHz are emitted by the transducer to the measured product, reflected by the product surface and received again by the transducer. They spread with sound…

Principles of Good Measurement - Guided Wave Radar     

High frequency microwave pulses are coupled on a cable or rod and guided along the probe. The pulse is reflected by the product surface and received by the processing electronics. This electronics evaluates the echo signal and converts it into…
