Understanding Base Sensors and Smart Sensors
Before we explore Smart Sensors, let’s start with the basics. A “base sensor” is a device that senses physical properties and produces an electrical output in response to a change. We’ve had sensors for years that can see, feel, hear, smell, and even taste. In the field of instrumentation and process control, these sensors are integrated into process control loops.
For example, a “Thermocouple” is a temperature sensor that generates increasing voltage as the temperature rises. In temperature process control loops, thousands of thermocouples are connected to transmitters. The voltage is conditioned and converted into an industry-standard signal that represents the controlled temperature range.
Enter the Smart Sensor
But what if a sensor could do more than sense a single physical property? Imagine a sensor that not only detects changes but also performs data conversion, digital processing, and can even communicate with external devices and “The Cloud.” That’s where the game-changing Smart Sensors come into play.
In essence, a Smart Sensor consists of a base sensor, a microprocessor, communication capabilities, and onboard diagnostics. This powerful combination opens up a wide range of functions and options. Smart Sensors can perform self-assessments, self-calibration, and detect issues such as sensor contamination, switch failures, and open coils.
The Versatility of Smart Sensors
The true power of Smart Sensors lies in their versatility. Some Smart Sensors are capable of multi-sensing, enabling them to measure pressure, temperature, humidity, gas flow, and more. As industry develops increasingly sophisticated and complex processes, Smart Sensors will become indispensable in the era of manufacturing intelligence.
