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.

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 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.

Temperature is one of the most measured physical parameters. Despite this, precise temperature measurement is one of the most difficult tasks in motor technology. To meet the constantly increasing requirements for improved motor performance, higher efficiency and reduced emissions, it is necessary to use reliable and precise sensors in modern motor control systems. The increased requirements over the last few years regarding measurement accuracy and reliability of temperature measurements has meant that many equipment operators must reconsider the suitability and performance capacity of their temperature measurement equipment. Resistant thermometers can be used between -200 °C and +850 °C. An important common property is that their output parameters are available in the form of electric signals that can be relatively easily transferred to measurement and control instruments for processing, storage and display.

This temperature sensor is for measuring the temperature of liquid and gaseous media in engines, sets of machines and utility vehicles. A Pt 1000 thin-film precision resistor is used as the measuring element. The temperature-dependent resistance of the Pt 1000 is evaluated by an electronic circuit and outputted as a temperature-dependent voltage at the sensor‘s output. The interrelationship between temperature and voltage corresponds to the characteristic curve for the Pt 1000 and is thus nearly linear. The assignment between temperature and output voltage is nearly freely selectable, the lesser temperature corresponding to the lesser output voltage. The sensor‘s lowest possible output voltage is 0.1 V and its greatest is 10 V. The output is overload-proof and short-circuit-proof. The sensor has no mechanical moving parts and so is not susceptible to vibration and soiling.

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.

The electronic temperature switch of BEDIA is fitted with thin-film resistor Pt 1000 in a bridge circuit. This sensor element provides close switch point tolerances and a quick response. Switch point and reset hysteresis may be selected within the admissible operating range when ordering so as to allow the monitoring of both very wide and very close temperature ranges. The switching output is protected from short-circuit and overload. The short-circuit current is limited by the output transistor switching off inthe event of a fault. It will automatically reset as soon as the fault has been remedied. The switch is available with ground-connected, plus-connected or potential-free DC switching output. The switch is open in the event of power failure or disconnection of the power supply, independed of the switching function. It is available both as normally open (NO) or normally closed (NC) switch.

These high-power bimetal operated temperature switches are available either with normally closed (NC) or normally open (NO) contact configuration. The robust round metal enclosure accommodates a resilient preloading disk, a bimetal disk and a silver contact. The compact switch system is covered by means of a plate which also carries a silver contact and is isolated from the enclosure by means of an isolating washer. The resilient preloading disk ensures excellent performance. The resilient preloading disk keeps the contact pressure constant throughout the entire temperature range of the BEDIA switch until switching occurs. The mechanically and electrically unloaded bimetal disk snaps over at a preset temperature, with either opening or closing the contact arrangement. The bimetal will only snap back to its initial condition after the temperature has dropped significantly.
