| | | GENERAL INFORMATION | | |
| | | |
| | | 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 industrial diesel engines and -industrial turbines. Rotary speed sensing is possible with gear wheels from module 1, with a max. switching frequency of 15 kHz. | | |
| | | For the selection of the right type along with the technical specifications 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-metals industrial partitions. | | |
| | | are based on the three-industrial 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 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. | | |
| | | |
| | | 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 SW-600 series is a range of industrial 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-10..., IAS-20..., IAS-60..., KAS-70..., KAS-80..., KAS-90..., and SW-600. | | |

| | | 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 pro | | |
| | | |
| | | The switching function of the sensors are mentioned in the type code: „S" = normally open „6" = normally closed „A" = antivalent (normally open / normally closed) I Furthermore we have sensors with analogue output. These sensors f' - r^'^-j have the description „IL" in the type code and supply a proportional output signal corresponding to the distance of an object to the active surface in the form of a 4 and 20 mA current output. As an object approaches, this current decreases to a minimum of 2.5 mA. The analogue sensors are particularly suitable for measurement and control engineering applications and are PLC-compatible. | | |
| | | be electrodes. For this reason it is necessary with this system that the container is of a conductive material oa ..substitute electrode" is fixed to the container wall, e.g. copper foil.These systems are available with industrial probes for analogue filling level measurement or for detection of 1, 2 or 3 measuring points. The position of the switching points and the analogue measuring area is user-definable within the possible effective range and therefore it can be determined for optimal matching oeach application. Level measurements of bulk material, liquids or pastes are possible with a dielectric constant as of er 1,1. | |
