For specific requirements, e.g. special-test benches, the standard parts can be combined with specific-designed parts to derive solutions corresponding to individual conditions. Advantages of the TOK-ZW coupling system: Lowest possible torsional stiffness utilizing two flexible elements Simple adjustment of the torsional stiffness by changing of elements Compensation of axial-, radial- and angular misalignment Self-centering, backlash-free and maintenance-free Flanges adapted to DIN or SPICER bolt patterns, respectively on demand Variable installation lengths utilizing telescopic spacer shafts Ideal for highest speed Lowest possible weight by using high-tensile aluminium and CFRP We are glad to see that you are interested in our product line and are happy...

Development and construction of test systems for environmental simulation, i.e. climate and temperature tests as well as corrosion tests (e.g. MEMS testing and automotive durability tests on tilt sensors, inclination sensors, inertial sensors, inclination sensors, automotive parts and many more). - Adjustable humidity - Typical temperature ranges are -72 to + 120°C - Parallel testing and calibration of more than 100 DUTs simultaneously per test run - Various interfaces to the DUTs can be switched like CAN, LIN, Flexray etc. - Database connection and automated data analysis using Microsoft PowerBi can be added.

We develop fully automatic test systems for inclination sensors and inertial sensors (MEMS, tilt sensors) according to customer requirements. With these systems, combined temperature and motion simulation is possible. We set quality standards with rate tables from Acutronic, for example. With the help of multi-axis rate tables, we can precisely position DUTs in end-of-line (EoL) test operations or for development purposes and calibrate and test them under temperatures of e.g. -40°C and up to 120°C. Merecs Engineering can also connect the test system to our customer's IT infrastructure, set up databases and automatic data analysis using Mircosoft PowerBI, so that important key figures such as First Pass Yield (FPY), process capability, system availability, statistics and trends are continuously updated and displayed on online dashboards. For example, more than 100 DUTs are possible per test run.

The main function of a shrink disc is the safe connection of a shaft with a hub by means of friction. For example, between a drive shaft and a transmission hollow shaft. The shrink disc generates a backlash-free connection by pressing the hub onto the shaft. This connection is mainly used to transmit torque. The shrink disc only provides the required forces, and transfers no forces or moments between shaft and hub by itself. It is not in the force flow. It is installed by sliding the shrink disc onto the hollow shaft and the subsequent tightening of the hydraulik system. By using conical surfaces the inner diameter reduces and the radial pressure is built up. After clamping the SHS will be locked mechanically and the hydraulic pressure will be removed. Due to this simple approach the SHS is suitable for repetitive clamping operations as they occur on a test bench, for example. Advantages of the SHS: – application-specific design/customization – relatively low pressure – very...

For use in harsh industrial environments, special sensors in particularly robust housings must be used. A water- and oil-tight cable connection is also often required, such as that offered by the M608A11 model. To protect against electromagnetic interference, a housing-insulated sensor construction and special amplifier electronics are used. Interference on the cable is also minimised by using twisted pair cables with additional shielding. Typical applications of such sensors include engine and transmission test benches as well as machine endurance test benches. — Industrial ICP®/IEPE accelerometer with integral 3m cable, terminating on cut-off cable -Measuring range ±50 g. — Sensitivity: 100 mV/g — Frequency range: 0.5 to 10000 Hz — With metric (M) or imperial mounting bolt For an individual quotation please contact us directly.

For the detection of NO and H2S an EDL (electrodeless gas discharge lamp) is used. A combination of both technologies (UVRAS & UVLEDs) allows simultaneous gas analysis of NO, NO2 and SO2 in the lower ppm range, which is particularly important in flue gas analysis (CEM)2. In the EDL, N2 and O2 are converted to NO and produce selective UV radiation. With this radiation a cross sensitivity free NO measurement is made possible. This method is called UV resonance spectroscopy (UVRAS). Applications Exhaust gas monitoring (CEM)2 Laboratory area Biogas research Industrial gas analysis Engine test benches Portable gas analysis (PEMS)3 Features & Benefits Simultaneous NOx and SO2 analysis Temperature controlled up to 55°C Fast response time < 3 seconds Durable EDL (> 16000h) Flow-independent measurement 0-2L/min No influence of gas humidity No NOx converter required High accuracy Low power consumption Compact size
