Testing two tyre inflator gauges simultaneously: ensure comparability and identical pressure conditions
Two tyre inflator gauges are to be tested in a workshop or inspection facility. Both...
Measuring dose rate behind shielding: correctly account for scattered radiation, geometry and measurement position
A radiation source is located behind massive shielding. A significantly elevated dose rate was measured...
Conductive or inductive conductivity measurement: evaluate electrode contact and contamination according to the medium
In a water treatment system, the electrical conductivity of clean process water is reliably measured...
Correctly inserting a melt temperature sensor in an extruder: avoid immersion depth and flow profile as measurement errors
An extruder appears to be running steadily. Barrel temperatures and heating bands are at their...
Handling gaps in time series: clearly distinguish missing measurements, zero values and interpolated values
A pressure sensor sends one measured value per minute to an edge gateway. In the...
Current transformers with high inrush currents: correctly assess saturation, transformation ratio and burden
An electric motor draws a current of approximately 80 A during normal operation. A current...
Check a pumped gas detector before pre-entry testing: test the sampling path for leaks and blockages
Before opening or entering a vessel, the atmosphere is checked using a pumped multi-gas detector....
Shielding mV/V load cell signals: correctly plan single-point grounding, equipotential bonding and EMC
A vessel weighing system initially operates stably during commissioning. As soon as the frequency converter...
Using an external reference in a dry-block calibrator: evaluate block indication and actual reference temperature separately
A dry-block calibrator is set to 100.00 °C. After the heating phase, the instrument shows...
Monitoring a dual sensor in a temperature transmitter: detect sensor drift through the deviation between two Pt100 sensors
At a critical process measuring point, two Pt100 sensors are installed in the same measuring...
