VEGAPULS C 23 radar sensor
VEGAPULS C 23 is a very accurate radar level sensor with a measuring range of up to 30 m suitable for water and industrial applications.
Advantages
- High measuring accuracy up to ±2 mm
- Zero temperature dependence
- The measurement is not affected by pressure or dust
- Accurate measurement even when foam is present on the surface
- Zero dead band under the sensor (with slightly increased measurement inaccuracy in the area up to 25 cm below the sensor)
- The narrow beam angle of 8 ° allows the sensor to be used even in confined spaces of underground sumps
- Independence of the measurement on the ambient noise generated when filling the tank
- User-friendly limit setting without the need to fill and empty the hopper
- No maintenance requirements (no condensation or dust on the sensor)
- Cheap radar sensor as a qualitatively more advanced replacement for ultrasonic sensors
- Two-wire connection of 4-20 mA to stations H1, H2, H3, H7, Q2, even in battery-powered assemblies operating in switched mode
Areas of application
Non-contact level measurement of bulk materials.
The sensor is able to measure liquids, even under high pressure and at extreme temperatures. It can therefore be used to monitor the level of wastewater sumps. The sensor is also suitable for applications with the highest hygienic requirements. The measurement is not affected by condensation on the sensor or foam on the measured level.
When measuring bulk materials, the sensor is resistant to both acoustic interference during filling and high dust and dust adhering to the sensor
Measurement principle
The sensor transmits a frequency modulated radar signal via an antenna system. The signal frequency changes sawtooth. The transmitted signal reflected from the medium is received by the antenna as an echo with a changed frequency. The frequency change is proportional to the measured distance.
