EGE-ELEKTRONIK SPEZIAL-SENSOREN GMBH

EGE flow sensors for explosive environments permit the space-saving flow measurement on site and the comfortable setting of the limit value using separate amplifier, e.g. within a control cabinet. The measurement takes place without mechanically moving parts using a thermal measuring element. The current flow state is displayed at the amplifier using LEDs. The devices are used wherever a safe, robust and low-maintenance monitoring of flow values is required. The measuring sensors of the product series ST 400 Ex; STS; STEX have ATEX approval and may, dependent on their design, be used in Gas-Ex areas requiring equipment for EPL Ga or EPL Ga/Gb. In the Dust-Ex area their use is permitted up to EPLDa.

EGE amplifier complement the EGE flow sensors without integrated amplifier. They process the signals of a measuring sensor and visualise the flow state using an LED indication. In addition, they provide switching or analogue outputs for flow and temperature to the control. The device set-up is easy and takes place using a potentiometer or the buttons on the front. The devices are installed in a control cabinet or comparable protected housing. The EGE amplifier of product series SKM 420; SKM 520; SKM 552 are suitable for supply with 24 V DC or 230/115 V AC.

EGE amplifiers process the signals of the EGE filling level sensors for extreme temperatures at a safe distance and are used to set up the sensor via intuitive operation using potentiometer and LED strip. Amplifiers for EGE high temperature limit switches feature an auto-calibration of the switching point at the press of a button. EGE amplifiers provide switching signals or analogue signals, dependent on the device.

The optical level switches are ideal for the detection of fluids with low DK value, such as lubrication oil, hydrocarbons or solvents. Optical level sensors detect the change of the refractive index during medium contact at the sensor tip. The sensors with stainless steel housing and glass tip are also suited for the detection of aggressive media, such as solvents. the sensors are available with Ex certification according to ATEX and IECEx.

The EGE IGEX family comprises intrinsically safe sensors for use in zone 0/20. The EGE IGEX proximity switches are based on the conventional inductive principle and switch when a metallic object comes close. This family also includes sensors climatic proofed and high pressure cleaning proof for use at extreme ambient temperatures up to + 140° C and down to -60 ° C with protection class IP 68 IP 69. The sensors are certified according to ATEX and IECEx. They are suited in the area of explosive dust and gas atmospheres for presence verification, position and movement monitoring and the counting of objects and the speed control on conveyor belts.

Inductive proximity switches of this product family cope with the most difficult environmental influences found during offshore use. The proximity switches are based on the conventional inductive principle and switch when a metallic object moves close. Contactless positioning tasks in seawater environments or even below the sea level require special properties, such as a high IP class, high pressure and impact resistance and seawater resistance. These properties are achieved by, for example, using materials such as stainless steel 1.4571, longitudinally watertight and seawater-proof cables or even a one-piece stainless steel housing. Sensors of this series can be used at a water depth of up to 300 m.

EGE amplifier for inductive proximity sensors complement the EGE sensors for extreme conditions from 200° C and the variants for -80° C. They are used for switching point adjustment and provide functional and output indications as well as the output signals. They also provide the 24 V DC power supply. The devices can be set up intuitively using a potentiometer. The analysis devices are suitable for top-hat rail assembly in a control cabinet. For 250° C-high temperature sensors a cable amplifier is available.

Sensors of the IFE family with a length of up to 900 mm are used to detect large metallic objects and offer a switching distance of up to 180 mm. The sensors are very robust, water-tight according to IP 68 and thus also suitable for outdoor use. The proximity switches are based on the proven inductive principle and switch con tactless when a metallic object moves close. Sensors of the family replace several inductive sensors connected in series. With their large sensor surface the reliably detect large moving metal parts. The sensors check for example the reinforcement in cast concrete parts during quality control or report the presence of railway rails for onward transport.
