The most common and popular sensors for temperature measurement include:
Thermocouples
Thermistors
RTDs (PTx)
Infra-red temperature detectors
Different types of temperature sensors. From left to right: thermocouple, thermistors, and RTD.
Millions of these sensors are at work every day in all manner of applications, from the engine temperature shown on our automobile dashboard, to the temperatures measured in pharmaceutical manufacturing. Virtually every industry utilizes temperature measurement in some way.
There are many types of sensors that have been invented to measure physical phenomenon:
Thermocouples, RTDs and Thermistors: for measuring temperature
Strain gages: to measure strain on an object, e.g. pressure, tension, weight, etc.,
Load cells: for measuring weight and load
LVDT sensors: LVDTs are used to measure displacement in distance
Accelerometers: measuring vibration and shock
Microphones: for capturing sound waves
Current transducers: for measuring AC or DC current
Voltage transformers: for measuring high voltage potentials
Optical sensors: used to detect light, transmit data, and replace conventional sensors
Camera sensors: used to capture single and continuous 2D images
Digital sensors: used for discrete on/off counting, linear and rotary encoding, position measurements, etc.
Positioning sensors (GPS): used to capture the longitudinal, latitudinal position based on GPS, GLONASS, and other satellite positioning systems. Different GPS sensors with different accuracy are available.
