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...
Temperature data loggers for the cold chain and storage: Reliably documenting limit values
Temperature-sensitive foods, pharmaceuticals, laboratory samples, chemicals and technical products often have to be stored within...
Selecting a hydrogen pressure sensor: Correctly assessing materials, seals and approvals
Hydrogen is used in electrolysis plants, compressors, storage systems, fuel-cell systems, test benches, pipeline networks...
Installing a load cell correctly: Avoid incorrect load application, unsuitable supports and force shunts
A high-quality load cell can only measure accurately if the mechanical design allows the intended...
