In order to ensure high product quality it is required to perform pressure and leakage test of each production lot. The test engineers are performing a rotary flexure test of the hydraulic joints and fittings according to the ASTM F -1387 standard. The customer required a universal data acquisition system in order to monitor and automate the test bench application.
For this test bench application the customer decided to use a high speed data acquisition system in combination with professional software.
The tests are performed in the following sequence.
- The hydraulic joints are mounted to 12 mm diameter tube which is 6 inch long.
- This tube is then mounted to a support rest on one side and to a rotating spindle on the other side.
- Then the spindle is rotating at a speed of 1750 rpm. While the spindle is rotating the pressure inside the tube is raise up to 25 bar.
This test is then running for 10 to 15 minutes to measure the twisting forces of the tube and to measure also the pressure level. If the pressure is declining the test engineer has an indication about leakages of the fitting seal rings.
The engineer can specify the part number of the product which is test. With a separate button he can then start the data logging and the test cycle. During the test the live data of speed (RPM), strain (Torque), deflection and pressure is displayed. At the end of the test a report is generated which shows a strip chart of all test data and a data table with all measurement values is available as well.
Customers are extremely satisfied with their new measurement data acquisition system. ProfiSignal can be easily set up and running without any real need for specific training. This is contrast to the majority of other, very complex products available on the market. But software and hardware is still capable of meeting both our simple and complex measuring requirements.
Summary of Benefits:
The advantage of the hardware system is:
- The hardware has universal analog and digital inputs for measurement of ration speed (pulses) and analog signal (mA, V, mV, TC, RTD) at the same time.
- The Software is a very easy to use development system for mimic building (HMI) and the programming for the data recording and reporting.
- The USB interface makes the configuration and set up of the whole system very easy.
