- EPLAN macros 9250
The new 9250/9251 generation of amplifiers combines all the features that make modern data acquisition truly successful. Network-compatible, highly accurate, easy to operate, intelligent and customisable to any requirement, the system consisting of amplifier module and fieldbus controller can be integrated into any existing system. In conjunction with the model 9251 fieldbus controller, the 9250 measuring amplifier delivers signals exactly where they need to be combined, examined and efficiently linked with other data. With the available fieldbus interfaces, you are flexible, perfectly cross-linked and save time, costs and other resources when connecting and integrating into existing systems. Automatic sensor recognition with burster TEDS means you can play it absolutely safe and protect yourself against unintentional incorrect parameterisation.
The wide supply voltage range enables operation on standard control cabinet supplies. The sensor signal is amplified by a high-precision amplifier. State-of-the-art microprocessor technology enables 24-bit AD conversion with high accuracy. The sensor supply is taken over by the amplifier module so that no additional voltage source is required. It can be set in the steps 2.5 V, 5 V, 10 V via the DigiVision configuration software. The maximum supply current of 40 mA allows several strain gauge sensors to be connected in parallel at the same time, e.g. for measured variable addition. Errors of measurement caused by changing cable lengths, but also by temperature fluctuations on the sensor cable, are compensated for by sense lines measuring the actual excitation voltage directly on site at the sensor itself (6-wire technology). Fluctuations there are immediately corrected by the electronics. The cut-off frequency of the amplifier can be switched between 10 Hz and 1 kHz.

- Multi-channel, universal measuring system consisting of up to 8 instrumentation amplifiers and a fieldbus controller
- Connection via PROFINET, EtherCAT or EtherNet/IP supports digital and fast measurement data acquisition in real time
- Highest flexibility due to a instrumentation amplifier for strain gauge, potentiometric, DC/DC and incremental sensors
Task
The poles of individual cells are welded in a vehicle battery assembly system. The poles of the up to 64 cells are connected with electrically conducting busbars using a laser welding procedure. In addition to a high degree of positioning accuracy a defined press-on force during the process must be 100 % guaranteed. In order to reduce the testing and cycle times, a force measurement is carried out at 8 poles in each case within the range of 400 to 500 N simultaneously. Measured value transmission takes place via 8 cascadable bus-capable instrumentation amplifier series 9250 and a PROFINET fieldbus controller model 9251 to a central control unit in real time.
Branchen

- Measuring ranges:
- Load: Fx = 1 kN / Fy = 1 kN / Fz = 2 kN
- Torque: Mx / My / Mz = 50 Nm - Low non-linearity from 0.1 % F.S.
- Customized axis configuration
- Robot flange according to DIN ISO 9049-1
Task
In a robot-controlled placement process, conclusions are to be drawn during the process about the correct parts, positioning and placement.
By means of a reference run, the forces and moments are recorded and serve as comparison parameters for the automated process. The distribution of the three forces and three torques provides information on completeness and alignment.
The placement process of workpiece carriers can be controlled, monitored and limited to maximum values, thus eliminating damage and rejects.
Branchen

- Measurement of press-in forces during an assembly process
- Precise determination of forces with the ring force sensor type 8438
- Multi-channel force measurement with up to 8 channels with one fieldbus interface
- EtherCAT, PROFINET and EtherNet/IP capable measuring system
Description
Battery trays must be carefully designed because they must protect the batteries, the heart of any electric vehicle, in the event of an accident. At the same time, it must be ensured that the battery trays can be opened if necessary, e.g. for maintenance of the battery cells. During the production of the battery trays, the bottom plate and the cover are connected by means of nuts. This connection must be secure, have guaranteed tightness, e.g. against dust, and be resistant to water pressure, as the battery cells are located in the space between them.
Special requirements
- High manufacturing quality of the battery trays
- Highest safety requirements
Solutions
Self-piercing nuts are used for the connection between the base plate and the cover. The press-fit process must have a 0-fault tolerance, which can be guaranteed with burster's process monitoring technology. The miniature ring force sensor 8438, which measures the press-in force, the potentiometric displacement sensor 8713, which determines the press-in displacement, and the combination of measuring amplifier 9250 and fieldbus controller 9251, which can be addressed with up to 8 measuring channels via a fieldbus interface and record and transmit the measured data, are used.

- Measuring ranges X: 1500 lbs, Y: 1000 Ibs
- Cross-talk < 0.5 % F.S.
- Up to 100 million load cycles
- Custom measuring ranges available on request
- Standardized rated outputs for easy replacement
Task
Vehicle tire testing places particular demands on our load cells. Measurements must be acquired and analyzed simultaneously in two directions, X and Y, which demands low cross-talk between the two channels. The other challenge is posed by the very large number of load cycles. In the event of a fault, maintenance staff must be able to replace the sensors quickly and reliably to minimize down times.
