Record measured values and measurement data digitally and with fast acquisition speed on the PC
Nowadays, recording measured values on a PC is a common method of collecting and analyzing data. There are a few important aspects to consider. First of all, it is important to use the right software for recording the measured values. This should be user-friendly and offer all the necessary functions to enter and save the data correctly. A clear user interface and intuitive operation are an advantage here. Choosing the right hardware is also crucial. Depending on the type of measurement, different devices such as sensors or measuring devices may be required. It is important to ensure that these devices are compatible with the PC and work together smoothly.
Who measured values or measurement data with a PC needs a solution that is quick and easy to use. These advantages - combined with very good resolution, electrical isolation and reliability - are offered by the Expert Key devices. All Expert Key devices are equipped with USB and LAN interfaces. Any sensors can be connected to the universal inputs. The measuring rate can be set individually up to a maximum of 100 kHz. With the software ProfiSignal the user from the laboratory, test bay or service department can keep an eye on his measured values or measurement data.
Application highlights of measured value acquisition on the PC
- Universal inputs suitable for any type of sensor (e.g. mA, mV, RTDs, thermocouples, incremental encoders, counters)
- ProfiSignal 20 Go analysis software and ASCII export enable fast evaluation of measurement data
- PC connection via USB, or networked via LAN
- High-speed acquisition of up to 100 kSamples/s
- Digital and/or PWM outputs
Practical example of measured value acquisition on a PC
Long-term testing of DC motors
Continuous monitoring using Expert Key devices in a test stand for brushless DC motors. Currents and rotations are recorded on more than 100 test samples and transmitted to a PC via a LAN. Monitoring then takes place of peak values and motor failures. All measurement data is portrayed and visualised in trends using the ProfiSignal Klicks software. Alarm lists enable easy processing of errors and failures. In this application, DC currents undergo high-speed sampling at 10kHz channel. ProfiSignal automatically computes RMS values and time-signal processes. Relatively slow measurements of rotation signals takes place simultaneously within a single system.
Typical areas of application
