Level sensor with 4–20 mA, HART or IO-Link: Selecting the correct signal and integration method
When selecting a level sensor, the measuring principle is usually the primary consideration. Depending on...
Zero adjustment on a Coriolis flowmeter: When zero adjustment is really necessary
A Coriolis flowmeter may indicate a small positive or negative mass flow even when the...
Voltage tester with continuity testing: When acoustic signals help with troubleshooting
Two-pole voltage testers are primarily used to detect electrical voltages and verify that an installation...
Data logger or online monitoring: When automatic alarm notifications are useful
Temperature, relative humidity, pressure and other measured variables are often monitored over extended periods in...
Humidity sensor in a cleanroom: Monitoring temperature, humidity and pressure together
In a cleanroom, monitoring the particle concentration alone is not sufficient. Temperature, relative humidity and...
Transmitter for converting 0–10 V to 4–20 mA: Why signal conversion is often necessary in practice
Different analogue signal standards frequently meet in existing machines and industrial plants. For example, a...
MINIMESS measuring points in hydraulic systems: Check pressure without shutting down the system
Pressure is one of the most important diagnostic variables in a hydraulic system. It shows...
Vibration sensors for pumps and motors: Detecting bearing condition and imbalance at an early stage
Pumps, electric motors, fans, compressors and gearboxes generate mechanical vibration during normal operation. Completely vibration-free...
Grounding an electromagnetic flowmeter correctly: Why equipotential bonding and grounding rings stabilise the measurement
Electromagnetic flowmeters are regarded as robust and low-maintenance measuring instruments for electrically conductive liquids. They...
Defining calibration intervals: Why operating conditions are more important than a fixed annual schedule
Many companies automatically calibrate their measuring and test equipment every twelve months. This schedule is...
