4…20 mA current is commonly used to connect process signals to a controller in industrial applications. Sometimes, an analog voltage signal or digital communications is used, but there are many advantages to using a current loo...

An RTD temperature sensor is a common device for temperature measurements in a wide range of industrial applications. In this article, we take a look at how they work, the most common types, and their advantages and disadvantag...

The design of intrinsically safe galvanic isolators such as the PR 9000 series of devices differs from Zener barriers. Both devices restrict the energy available to the hazardous area, but by using components such as transforme...

In the realm of industrial process control and factory automation, signal conditioning devices play a crucial role in ensuring the accurate transmission of process values. These devices also ensure that the resulting signal is...

The ability to split an analog signal is a much asked for feature. Whether to simply add a local indicator or to use the additional signal as an input to a separate process or system, signal splitting is a commonly used technique.

Electromagnetic interference, or EMI, is commonly found in industrial environments, and can adversely affect the accuracy of your instrumentation signals – here are some tips and advice that can help ensure accurate measurement...

Frequency to current converters are used in control systems to transform a pulse or frequency to an equivalent current signal.

With reference to IEC 60079-11, an intrinsically safe circuit is one which during normal operation and under specific fault conditions does not generate a spark or have sufficient thermal energy to cause ignition of an explosiv...

Thermocouple and RTD sensors are commonly used to measure temperature in industrial processes. In cases where these sensors are connect directly to the PLC, the result of the measurement accuracy is sometimes worse than expecte...
