Thermocouple elements are temperature sensors that are useful over a wide range of temperatures. They are used with thermocouple temperature probes, bimetallic devices that are suitable for various temperature sensing applications.
Pressure transmitters function by measuring the amount of pressure that is exerted on their sensors. It measures mechanical pressure and converts it to electrical signal.
The sensors that an engineer puts on a robot are entirely dependent upon the functions that the engineer perceives that the the robot will be called upon to perform. Some, but not all, of the sensors may be: proximity sensors, pressure sensors, light sensors, magnetic sensors, a camera, temperature sensors, accelerometer, speed sensor... The question isn't, "what sensors does a robot have", but rather, "what sensors does the engineer think that the robot should have?"
Sensor technology has several limitations, including sensitivity to environmental conditions, which can affect accuracy and reliability. Many sensors have a limited range and may require calibration for specific applications. Additionally, issues such as sensor drift, noise, and potential interference from other electronic devices can compromise data quality. Furthermore, the cost and complexity of deployment and maintenance can be barriers in some applications.
Resistance can be changed by strain over time and changes in the temperature. Resistance thermometers are sensors that are used to measure temperature by correlating the resistance of the RTD elements.
