An abundance of remote sensors are connected to the industrial control management infrastructure. These sensors collect and communicate process and environmental information back to the automation controllers. Within the wide range of sensor types used, the most common are temperature, pressure, and vibration. Standard outputs used for communications include analog voltage or current, smart digital, and digital on/off (in the case of threshold sensors).
Field instruments are handheld devices that are frequently used to maintain, repair, and calibrate remote sensors. These devices are typically battery powered and require precise sensor interface electronics.
