Rotonivo®

RN 3000 RN 4000 RN 6000

Principles of functionA motor driven shaft causes a vane to rotate. Once the material level reaches the vane, thereby preventing further rotation, switches are activated which result in an output signal and the motor stops. Once the vane is free again from material, the output signal is reset and the motor driven shaft rotates again.

Vibranivo®

VN 1000 VN 2000 VN 4000

VN 5000 VN 6000

Principles of functionElectronically stimulated piezos cause the fork to vibrate. As soon as the sensor is covered with material, the vibration is dampened and the resulting electrical current change causes the output signal to switch. Once the material level falls below the sensor, it is free to vibrate again and the output signal is reset.

RFnivo®

AnfordeRF 3100 RF 3200 RF 3300

Principles of functionThe capacitive level limit switch is automatically calibrated to a reference capacitance of an empty container. If the probe is covered by the product, the measured capacitance changes on the sensor through the dielectric and a switching signal is activated. The integrated “Active Shield“ technology ensures high reliability even for products that cause caking.

Bulk materials with very low DC value > 1.5 Applications with process pressure up to 25bar Vibration in the container High safety standard High hygiene requirements Simple to install and set up PFA coating Temperature range from -40°C up to +500°C High quality process materials (VA 1,4571/1,4404, ceramics, PPS)

Capanivo®

CN 4050

CN 4020

CN 4030

Principles of functionThe electrodes in the sensor make up a capacitor. As the level of the material changes, the capacitance changes as well. The integrated electronics evaluate the change in capacity and convert it to a switching signal. The capacitive measuring principle places no special requirements on assembling, mounting or installation.

Nivobob®

AnfordeNB 3000 NB 4000 SLB 300

Principles of functionA sensor weight, attached to either a metal tape or rope, is electromechanically lowered into the vessel. Once the sensor weight rests on the material, the winding direction of the motor changes and the sensor weight is rewound to the upper stop position. As the weight is lowered, the distance is electronically measured. Microprocessors convert the measured distance together with the programmed silo geometry into a volumetric output signal. This signal is updated each time the sensor weight is lowered.

LR 560

KN 2700 KN 2800

FN 6

Special Solutions

Principles of functionThe robust stainless steel construction makes the LR560 FMCW radar level transmitter extremely suitable for all kinds of industrial applications. The unit operates at a high frequency of 78 GHz thus achieving a very small beam angle which eliminates any signal interference at the flange but allows optimum reflection of the bulk solids material.

SITRANS LR 560 Radar

Principles of functionThe conductivity of a material allows electricity to flow between the Kondunivo process connection and the probe when the sensor is covered with material, resulting in an output signal. As soon as the material level falls, the electrical circuit is broken and the output signal is reset. Alternating current is used to prevent corrosion of the sensor probe and an electrochemical reaction of the material. To ensure reliable measurement in a variable liquid surface, an adjustable output signal delay is standard. The Kondunivo can be used in metal, as well as non metal vessels.

Kondunivo®

Principles of functionA vibrating fork sensor (Vibranivo®) attached to a tape can be lowered accurately to within millimeters to the required measurement point in the vessel. This allows both flexible point level measurement, as well as batch measurement. The Flexinivo® is programmed via an external SPS controller.
