How to choose the right sensor for the job

For controls engineers developing machinery for factories or plants, sensor selection is a pivotal aspect that directly influences system performance, reliability and safety.

In industrial automation, sensors monitor critical variables such as temperature, pressure, flow rates and machine positioning, ensuring precise control and adherence to safety standards. Machine Design reported that applications of sensors extend across automated manufacturing environments, where their integration facilitates robotics, navigation and collision avoidance.

By understanding the different sensor technologies—such as reed switches, Hall effect sensors, thermistors and Pt-RTDs—engineers can tailor their choice based on the specific demands of the application, from proximity detection to temperature control. Each sensor type offers distinct advantages, whether it’s the high sensitivity of TMR switches or the wide temperature range of Pt-RTDs.

Additionally, partnering with the right sensor supplier is critical for the long-term success of automation projects. Engineers must consider suppliers who provide comprehensive product lines, technical application support and custom engineering options.
