ckm105en2106h  1/3Thank you for choosing a NIVELCO instrument.We are convinced that you will be satisfied with our product!1. APPLICATIONThe NIVOCAP CK capacitive level switches operate in the RF (radio-frequency) ~ 130 kHz range.The instrument is less sensitive to material adhesions caused by the measuring probe's design and the so-called referenceprobe-based operating principle. The device is capable of level switching in solids and powders with a dielectric constantgreater than 1.5 relative permittivity (Ɛr) and to a limited extent in liquids (see 2.1 General data).The device needs to be calibrated after it is installed.During operation, the device evaluates the capacitance difference of the connected probe continuously. Until the probe isin the air (the medium does not reach the probe) the measuring and reference probe is at the minimal capacitance value(εrelative =1) relative to the instrument housing. When the medium reaches the probe, the capacitance will increase(εrelative≥1). The device measures the capacitance change relative to the reference value stored during the calibrationprocedure.The reference probe is designed so that the material deposits on the probe are ignored, preventing any false switching.There are four measuring ranges switchable on the device (see Chapter 4: Sensitivity Ranges)4 th sensitivity range: 0.5 pF, εrelative = 1.5…2.03 rd sensitivity range: 2.5 pF, εrelative = 2.0…4.02 nd sensitivity range: 8.0 pF, εrelative = 4.0…7.01 st sensitivity range: 18 pF, εrelative = > 7.02.
