An intelligent SIDSP sensor enables the MiniTest FH to provide high-precision measurement and reproducibility while compensating for the influence of temperatures in the measuring environment and in the object being measured. A wide range of sensors allows to adapt to different applications and measuring tasks.
Thickness is determined by measuring the distance of a reference ball or wire to the sensor tip. The reference ball is attracted by a powerful magnet positioned directly behind the sensor tip. The steel target balls are treated according to a specialized ElektroPhysik procedure which allows reproducibility of test results of up to 0.5%.
Special features such as an automatic calibration function for zero calibration and direct transfer of readings into a spreadsheet or CAQ system complement the high user comfort provided by the intuitive menu operation.
- High precision wall thickness measurement up to 24 mm
- Exceptional accuracy and repeatability through sensor-integrated digital signal processing (SIDSP®)
- 2 million readings storable in more than 200 batches
- Up to 20 readings per second
- Wear-resistant sensors with hardened sensor tips
- Direct data import into evaluation software
- Bluetooth, USB and RS 232 C interfaces
- IP 65 Water and Dust Resistance
