Industrial temperature sensors - Import export

Inductive sensors from Micro-Epsilon are based on the eddy current principle and designed for non-contact measurement of displacement, distance, position, oscillation and vibrations. They are particularly suitable when high precision is required in harsh industrial environments (pressure, dirt, temperature). Inductive sensors from Micro-Epsilon offer extremely precise measurements where sub-micron accuracy is required.

BEDIA level monitoring sensors are used to monitor the filling levels of liquids. The sensors detect when a filling level is exceeded or falls below a limit. Water-based liquids 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 occurs 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. This signal is processed by a microcontroller-based evaluation circuit which activates or deactivates an output stage.

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

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 precise and compact surfaceCONTROL 3D 3500 3D sensor is ideal for automated inline inspection of geometries, shapes and surfaces on diffuse reflective surfaces. With a z repeatability of up to 0.4 µm, the sensor sets new standards in high-precision 3D metrology.

The profilometer thicknessCONTROL TCP8301.T-Offline is applied for sampling regarding the extrusion process of treads, side wall and inner liner material. The system offers measuring results in high precision and allows therefore an efficient production as well as a fully recorded quality control.

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.
