Understanding a Calibration Certificate: Correctly Assessing Measurement Deviation, Measurement Uncertainty and Tolerance
A calibration certificate often contains numerous measured values, tables, uncertainty statements and technical notes. Nevertheless,...
Connecting DIN-Rail Transmitters Correctly: Planning 24 V DC, Input and Output
DIN-rail transmitters connect sensors, electrical measured variables and control systems. They convert, for example, a...
Humidity Sensor with 4–20 mA or Modbus: Selecting the Signal for HVAC and Building Automation
Humidity sensors in ventilation systems, plant rooms and buildings often measure not only relative humidity...
Current and Voltage Data Loggers: Identifying Load Profiles and Voltage Dips
Many electrical problems do not occur continuously. A machine may shut down only occasionally because...
Digital Pressure Gauge with Switching Output: Monitoring Pressure Limits Directly
A digital pressure gauge displays the current pressure directly at the measuring point. If the...
Finding Compressed-Air Leaks with an Acoustic Camera: Industrial Leak Detection
Compressed-air leaks often remain undetected in industrial installations for a long time. Small leaks at...
Protecting Force Transducers Against Overload: Planning Stops, Safety and Installation Correctly
Force transducers used in test benches, presses, assembly fixtures, weighing systems and machines are frequently...
Telescopic Probe for Radiation Measurement: Increasing Distance, Locating Hotspots and Improving Safety
Telescopic probes make it possible to measure the dose rate at potentially higher-radiation or hard-to-reach...
Gas Density Monitor or Gas Density Sensor: Monitoring SF6 Gas Density Safely
In SF6-insulated medium- and high-voltage switchgear, gas density is a decisive operating parameter. If the...
Simulating an mV/V Signal: Testing Load Cells and Strain-Gauge Sensors Correctly
Load cells, force sensors, torque transducers and many melt-pressure sensors do not provide a direct...
