Electric Air heater Electrical air heater type “LEH-A” are intended for the heating of gaseous media. The main applications are the heating of air in ventilation - / air conditioning or heat-recovery installations. Wide use areas are applications of the process - / environment-technology i.e. at the catalytic afterburning of exhaust fumes or drying ovens or in the plastic - / textile or paper industry. Through a variable construction concept, diverse use possibilities emerge. The application of highly compacted electrical heating elements with high purity compacted magnesium oxide powder sheathed metal tube and the direct heat transfer at the medium to be heated leads to an efficient realization of the electric energy to thermal energy. Special materials of acid constant rustproof steel stand for the heating of aggressive media by disposal. Alternatively, the heaters can be delivered also in the materials INCOLOY, INCONEL, HASTELLOY and MONEL. The air heater essentially consist of the following main-components: Process flange Rod heating elements Temperature Sensors (Thermostat / Thermocouple / RTD) Electrical terminal box

The capaNCDT DT61x4 is an active, capacitive system for displacement, distance and position measurements. Consisting of a sensor with integrated preamplifier, a robust cable and a compact controller, the measuring system is immediately ready for use without any on-site calibration. The measuring system is available with a cable length up to 15 m and is ideal for automation purposes. The capaNCDT 61x4 is particularly suitable for automated robot manufacturing and measurement tasks with a drag chain. Moreover, it is used in machine building and semiconductor production. For optimum signal quality, the desired cable length is already factory-calibrated.

The quality of electrode film is crucial for increasing the performance of future battery generations. In order to generate higher energy densities, coating and calendering processes must be performed with the highest precision. Micro-Epsilon offers high-precision measuring systems for the thickness measurement of coated and uncoated battery film. These systems are equipped with high-resolution sensors and increase process stability, production speed and quality in modern coating lines.

White light interferometers use infrared light in the non-visible range (approx. 840 nm wavelength), which means that the measurement position cannot be seen. To visualize the measuring position, Micro-Epsilon systems are equipped with a pilot laser which projects a light spot onto the measuring position. In addition, the pilot laser uses a patented method to provide feedback on the distance in addition to the measurement position. If the measuring object is at the correct distance and within the measuring range, a constant glow is emitted by the pilot laser. If the measuring object is outside the measuring range, the pilot laser flashes.

The confocal chromatic confocalDT measuring system is used for fast distance and thickness measurements. Different sensor models and controller interfaces open versatile fields of application, e.g., in the semiconductor industry, glass industry, medical engineering and plastics production.

BEDIA level monitoring sensors are used to monitor the filling levels of liquids. The sensors react when a filling level is exceeded or falls below a limit. Aqueous mediums like coolants, AdBlue®, fresh water, waste water, bilge water and oil-based liquids like motor oils, hydraulic oils, fuels and brake fluids can be monitored. Since they contain no mechanical moving parts, their function will not be influenced by dirt particles or other influences. No electrical current is sent through the medium via an electrode with BEDIA sensors, an electrolysis of the medium is not possible. Operating Principle The function of the sensor is based on the capacitive principle. It detects the change in capacitance that arises when an electrode surrounded by air is immersed into a liquid medium. This change in capacitance at the electrode of the sensor excites an oscillator, causing it to oscillate. Then this signal is processed by a microprocessor-based evaluation circuit.

Types of Media The level monitoring sensors are designed for two different media types: For electrically conductive liquid media with relative permittivity within a range of εr 35 … 85 (water, coolant, water/glycol mixture) For electrically non-conductive liquid media

Predictive maintenance needs measured data to the greatest possible precision. On components with moving or rotating parts, the relevant measuring points (e. g. temperature of an electric motor’s rotor or planetary gearbox bearing) sometimes cannot be accessed with wired sensors. Accordingly, the data needed for condition monitoring can be obtained only with complex calculations and estimates. However, precise and reliable measured data are obtained only when a sensor is placed directly on the moving part. For requirements of this kind we have developed NORIFID, a simple, cost effective measuring system that is based on established technologies, supplies wirelessly power by induction to a sensor on a moving part, and transmits the measured data via RFID to a fixed receiver.

Conventional thermometers measure the temperature by means of length or volume change of a material, and are only suitable as display instrument. Temperature sensors from Lenord+Bauer use resistance thermometers that feature an almost temperaturelinear resistance curve, and output the resulting measurement data as electrical signal. They are suitable for a measurement range from 40 °C to +250 °C. A thin stainless steel tube protects the electronics from dirt, humidity and corrosion, allowing the sensors to meet the requirements of protection class IP 68. The sensors are in compliance with fire protection standards EN 45545 and are typetested according to EN 50155. • Platinum resistance thermometer Pt100 / Pt1000 • Measuring tube lengths from 30 mm to 140 mm • Connection with 2, 3 or 4wire technology • Fire behaviour according to DIN 5510 and NF F16101 • Custom configuration
