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...
