Coriolis measurement in dosing and filling: Measuring mass instead of volume
Dosing and filling processes must be repeatable, fast and traceable. Whether food, additives, chemicals, paints,...
Calibrating HART transmitters: Checking analog signal and digital parameters together
HART-capable transmitters are widely used in process automation. They provide a classic analog 4–20 mA...
Checking SF₆ gas quality: Correctly evaluating moisture, purity and decomposition products
SF₆ gas is used in gas-insulated switchgear as an insulating and arc-quenching gas. For the...
Selecting a gas detector: Which gases really need to be monitored?
Anyone who needs to select a gas detector is often faced with a fundamental question:...
Finding voltage dips: How the Min/Max function and data logger in a multimeter help
Sporadic voltage dips are among the most unpleasant faults in electrical systems. During a normal...
Pressure transmitters for small measuring ranges: Why mbar measurements are particularly demanding
Small pressure ranges in the mbar range may seem uncritical at first glance. In practice,...
Pneumatic or hydraulic pressure calibration: Which medium is right?
In practice, the same question comes up very often in pressure calibration: Should calibration be...
Vortex flowmeter shows fluctuating values: Process pulsation or wrong measuring point?
When a vortex flowmeter shows fluctuating values, the cause is often first suspected in the...
Hydrogen pressure sensor in the test bench: Considering dynamics, accuracy and temperature range
Hydrogen test benches place high demands on pressure measurement technology. In development, research, fuel cell...
Simulating Pt100: Testing temperature measurement without a real temperature process
In practice, temperature measuring chains are often only checked when measured values appear implausible, a...
