Furthermore we have a large number of ATEX certified products. For the ATEX products we provide a separate catalogue.

For applications where there are hot ambient condition, we offer inductive and capacitive sensors with integrated electronics which dependent on the model can be used for applications with ambient temperature of +100*C, +120@C and even up to +160*C.

Moreover for extreme ambient product temperatures up to +250@C we have high temperature sensors with remote electronics.

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.

The sensors are used to detect objects, for counting functions and for all types of level monitoring applications (liquid and solid materials).

Inductive sensors (IAS) feature transistorised oscillators whose power consumption is influenced by the approach of metals and other electrically conductive materials such as carbon. Non-conductive metals can also achieve this effect.

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.

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. They are suitable for rotary speed sensing, for detection of gearwheels and for standstill control.

Areas of use can be heavy construction engines, rail vehicles, large diesel engines and -turbines.

Rotary speed sensing is possible with gear wheels from module 1, with a max. switching frequency of 15 kHz.

The SW-600 series is a range of flow sensors based on the calorimetric measuring principle. This principle is based on the physical effect that flowing medium absorbs heat energy. The cooling of the sensor tip by the flowing medium is registered and electronically evaluated.

Flow sensors are an essential component of processing- and operation plants in systems technology in order to ensure operational safety. They are used for detection of liquid media and for coolant supply as well as for operation control at pumps.

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-IO..., IAS-ZO..., IAS-6O..., KAS-TO..., KAS-8O..., KAS-90..., and SW-600.

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.

KXS Systems are used for applications where the sensing distances of standard sensors are not su#icient.

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.

The Capacitive Filling Level Systems (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 the probes for analogue filling level measurement or for detection of 1, 2 or 3 measuring points. The position of the switching points amd the analogue measuring area is user-definable within the possible effective range and therefore it can be determined for optimal matching of each application. Level measurements of bulk material, liquids or pastes are possible with a dielectric constant as of €r 1,1.

For the selection of the right type along with me technical speciflcations the following parameters are important:
There are two different types of capacitive and inductive sensors. Sensors for flush mounting or models for non-flush mounting where the sensor has an exposed head.

Flush mountable sensors are particularly suitable for detecting solid objects without direct contact and for sensing liquid or solid levels through non-metal partitions.

The non-flush mountable sensors are designed for applications, in which the medium to be monitored comes in direct contact with the sensor. In such level monitoring systems, the sensor head is completely immersed in the powder, granulate or liquid.

The switching funstion of the sensors are mentioned in the type code:


Furthermore we have sensors with analogue output. These sensors have the description "IL" in the type code and supply a proportional output signal corresponding to the distance of an object to the surface in the form of a 4 and 20 mA current output. As an object approaches, this current decreases to a minimum of 2.5mA. The analogue sensors are particularly suitable for measurement and control engineering applications and are PLC-compatible.
