MID shows no flow: empty pipe, incorrect conductivity or parameterization?
If a magnetic-inductive flow meter, or MID for short, shows no flow, a defect in...
Pressure transmitter shows incorrect values: is the cause the sensor, process or scaling?
When a pressure transmitter shows incorrect values, the sensor itself is often suspected first. In...
CAT III and CAT IV for voltage testers: why the measurement category is decisive
When selecting a voltage tester, many users first look at the voltage range. 690 V,...
Testing TT, TN and IT systems: why the network system affects the test procedure
When testing electrical installations, the measuring instrument is not the only factor that determines a...
Thermocouple reads incorrectly: installation error, cable influence or wrong sensor type?
When a thermocouple displays incorrect temperatures, the sensor itself is often suspected first. In practice,...
Digital pressure gauges with output signal: when 4–20 mA or RS485 makes sense
A digital pressure gauge is often used when the pressure should be easy to read...
Multi-channel temperature data loggers: when several measuring points are important at the same time
In many applications, temperature is not only required at one single point. In processes, plants,...
Measuring humidity and temperature together: why a combined sensor is often better
Temperature and humidity are assessed together in many applications: in warehouses, museums, production rooms, control...
Galvanic isolation in measurement signals: when isolation amplifiers and transmitters are needed
In industrial measuring circuits, signals must be reliably transmitted from sensors, transmitters and field devices...
Diaphragm seals for viscous or crystallizing media: preventing clogging
When pressure sensors, pressure transmitters or pressure gauges are used in systems with viscous, sticky,...
