4. Technical Data SONO-VARIO
SENSOR DESIGN
Casing: High Grade Steel V2A 1.4301
SONO-VARIO
Standard
: The probe head surface consists of stainless steel with
abrasion-resistant aluminium oxide ceramic.
SONO-VARIO
Xtrem
: The probe head surface consists of hardened steel with
highly abrasion-resistant special ceramic.
SONO-VARIO
LD
: The probe head surface consists of stainless steel with
abrasion-resistant special ceramic.
Available are high-temperature versions of the SONO-VARIO up to 150°C with
external measurement transformer SONO-ES upon request!
MOUNTING
Sensor Dimensions:
SONO-VARIO
Standard
: 108 x 45mm (Diameter x Length)
SONO-VARIO
Xtrem and LD
: 108 x 71mm (Diameter x Length)
The mounting flange can be screwed on to the rear side of any container, hopper or silo.
MEASUREMENT RANGE MOISTURE
The sensor measures from 0% up to the point of material saturation. Measurement
ranges up to 100% moisture (pure water) are possible with a special calibration.
MEASUREMENT RANGE CONDUCTIVITY
The sensor, as a material-specific characteristic value, delivers the radar-based conductance
(RbC
–
R adar- b ased- C
onductance) in a range of 0…12dS/m. The conductivity range is reduced
in moisture measurement ranges >50%.
MEASUREMENT RANGE TEMPERATURE
Measurement Range
: 0°C …100°C
The temperature is measured 3mm beneath the wear-resistant sensor head inside the
sensor casing and is issued at the analogue output 2. The material temperature can be
measured with an external calibration and compensation of the sensor intrinsic-heating.
MEASUREMENT DATA-PREPROCESSING
MEASUREMENT MODE CA: (Cyclic-Average) For relative short measuring processes with
continual average value, filtering and an accuracy of up to 0.1%
MEASUREMENT CF: (Cyclic-Float-Average) For very slow measuring processes with
floating average value, filtering and an accuracy of up to 0.1%
MEASUREMENT MODE CS: (Cyclic-Successive) For very short measuring processes
without floating average with internal up to 100 measurements per second and a cycle time of
200 milliseconds at the analogue output.
