While analytics and other Big Data technologies might be the ‘brains’ of the IIOT, transducer systems are the nervous system; continuously gathering information and streaming data to processing centres. Industrial internet systems depend on sensors for continuous, accurate information to measure pressure, temperature, volume, orientation and other parameters.
A lot of attention has been given to the roles of automation and machine learning in future industrial technology. However, software advancements will only provide limited capabilities without cutting-edge sensor technology.
Consider the following examples of industrial transducer technology:
- Temperature - There are several kinds of sensors used to measure temperature. The two primary kinds are Contact type and Non-contact type. These categories are divided into mechanical temperature sensors, Electrical temperature sensors, Thermocouples, Resistance thermometers and Silicon band gap sensors. These sensors are used for the maintaining of temperature-sensitive systems.
- Force – Strain gauge technology allows measuring force precisely and fast. Therefore strain gauges measure the deformation of objects and change the mechanical impact into a change of electrical resistance
- Torque – Similar to force strain gauges allow also the measurement of torque. Many torque meter measure rotating speed simultaneous so that mechanical power can be calculated
