An experienced, in-house team of test and analysis specialists stands for the peak of quality – product-specific and exactly as you, the customer, desire it. To ensure quality in serial manufacture early on and guarantee a frictionless start of production, test equipment is incorporated into manufacturing processes and automated production lines. Test contacts on the circuit board, produced for just this purpose, are contacted by fine, spring-loaded test pins. Depending on the series size, the in-circuit test can take place manually or in an automated fashion. In combination with other test processes, including tests without test contacts, over 90 percent of all errors can be detected.

Based on your ideas and in close collaboration with your specialists, PRUFREX takes part in the development of your new products. Our deeply ingrained processes and long-term supplier relationships allow us to realise both test series and A B and C models with great rapidity. We will produce the functional models and later series on identical machinery.

thicknessGAUGE C.LL sensor systems use laser triangulation sensors for the thickness measurement. These laser sensors enable high measuring rates at high speeds. The thicknessGAUGE.laser series impresses with a favorable price/performance ratio and is preferably used for thickness measurements of common surfaces such as plastics, wood and metals.

Alongside the standard ICT/FCT process, we can also target every individual production stage for verification, as requested. Efficient inspection strategies and final functional tests are a fixed component of our quality management system. This electrical test process is ideal for testing smaller numbers of units, such as for pre-production, prototype or pilot series. The rapid test creation process allows, among other things, flexible reaction to product changes. Flying probe tests can be rapidly set up and are cost-efficient.

Our fully automated winding centres for fine and self-bonding wire make us the perfect partner for any tasks you require. Our coils are tinned with lead-free coatings (RoHS). We can wind onto any desired coil form using many different press-in ferrite and metallic cores. Multiple tap coils are also possible. Pins are automatically applied to the coil connections during the winding process, with wire drawing electrically controlled. Our winding machines handle single-chamber and multi-chamber coils with wire thicknesses from 0.045 to 0.71 millimetres.

Our fully automated winding centres for fine and self-bonding wire make us the perfect partner for any tasks you require. Our coils are tinned with lead-free coatings (RoHS). To manufacture self-supporting coils, we use self-bonding wire. During winding, the surface of the wire is bonded using hot air. To ensure the coil connections can be soldered, they are then stripped of insulating enamel using a fully automated milling process. PRUFREX is able to make air core coils with wire thicknesses from 0.045 to 1.6 millimetres.

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.

Alongside the standard ICT/FCT process, we can also target every individual production stage for verification, as requested. Efficient inspection strategies and final functional tests are a fixed component of our quality management system. PRUFREX is a manufacturer of test systems and software.

Using the entire range of available test procedures, we will develop a strategy that suits your product.

Alongside the standard ICT/FCT process, we can also target every individual production stage for verification, as requested. Efficient inspection strategies and final functional tests are a fixed component of our quality management system. In our test laboratory, we are able to carry out static and cyclical environmental simulation for you, from air-to-air and liquid-to-liquid thermal shock tests to storage temperature and humidity tests. Based on the environment in which the product is to be deployed, we will draw up a tailor-made quality assurance programme. Through simulation of the conditions that cause ageing (e.g. large temperature fluctuations) we can ensure that the product will reach the required service life. Products are also subjected to further customer-specific tests in fields such as EMC, overload resistance and mechanical loading.

Our fully automated winding centres for fine and self-bonding wire make us the perfect partner for any tasks you require. Our coils are tinned with lead-free coatings (RoHS). At PRUFREX, single-chamber and multi-chamber coils can also be achieved using two-wire windings. For specific magnetic flux requirements, we apply wires of different thicknesses to the coil form. Two different wire thicknesses, from 0.045 to 0.71 millimetres, on coil forms with press-in ferrite or metallic cores.

What do we take care of from the very beginning? Among other things, making sure the outside edges of circuit boards benefit production, thinking about how a housing can be perfectly planned in, working out where connectors will be a nuisance or where wide mechanical tolerances can be permitted. For decades, we have developed and produced together under one roof. Engineering in a way that benefits manufacture is part of our company DNA.

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.
