Capacitive Sensors (KAS)
Capacitive sensors (KAS) react to metals and non-metals that exceed a specific capacitance on approaching the active surface. The sensing distance with respect to a specific material is greater the higher the dielectric constant. Applications: The sensors are used to detect objects, for counting functions and for all types of level monitoring applications in liquid materials (i.e. water, oil, acids, glue) and bulk materials (i.e. powder, granulate, pellets).
Capacitive Sensors with extreme long sensing distance (KXS)
The capacitive sensors with extreme long sensing distance (KXS/KXA) are based on the three-electrode measuring-principle. This measuring principle allows much larger sensing distances compared to the two electrode principle of common capacitive sensors (KAS), up to 10- times the norm. Although one achieves essentially larger switching distances with these capacitive systems, the size of the sensors is small. Applications: KXS Systems are used for applications where the sensing distances of standard sensors are not sufficient. A further feature is the Duplex- or Triplex-operation. With the corresponding evaluation unit it is possible to adjust 1, 2 or 3 switching points with only one sensor.
Capacitive Level Measurement Systems (KFI / KFS / KFA / KFX)
The capacitive level measurement systems (KFI / KFS/KFA/KFX) operate according to the three-electrode principle. With this principle the container or an additional electrode serve as a counter-electrode to the probe electrodes. For this reason it is necessary with this system that the container is of a conductive material or a “substitute electrode” is fixed to the container wall, e.g. copper foil. These systems are available with probes for analogue filling level measurement or for detection up to 4 measuring points. The position of the switching points and the analogue measuring area is custom made within the possible effective range and therefore it can be determined for optimized matching of each application. Applications Level measurements of bulk material, liquids or pastes are possible with a dielectric constant as of εr 1,1.
Magneto Resistive Sensors (MRS)
The magneto resistive sensors (MRS) detect the movement of ferromagnetic materials, by means of the change of the magnetic flow. They are available with (Series 350) or without (series 300) detection of direction of rotation. Applications: They are suitable for rotary speed sensing, for detection of gearwheels and for standstill control. Areas of use can be extremely rough, max. switching frequency of 15 kHz.
Inductive Sensors (IAS)
Inductive sensors (IAS) feature transistorised oscillators whose power consumption is influenced by the approach of metals and other electrically conductive materials such as carbon. Applications: These devices can be used as limit switches and position sensors for monitoring and positioning applications in machines and installations as well as pulse generators for counter systems, distance measurements, speed control and many other applications.
Power Supplies / Isolating Switching Amplifiers (Ex Barriers)
The EG…-130-… series control units contain a DC-side short-circuit protected power pack, voltage stabiliser and output relay. These control units can be actuated by all 2, 3 and 4-wire sensors with PNP, NPN, NO, NC or antivalent functions, i. e. our series IAS-10…, IAS-20…, IAS-60…, KAS-70…, KAS-80…, KAS- 90…, and SW-600.
