Sensors, transducers and detectors covers a wide category of devices used to monitor, measure, test, record, analyze and/or display data as generated due to changes in a measured norm. All manner of sensors, transducers, and detectors are included in this grouping; from unpackaged sensor chips or elements; to complete indicators, gauges, switches, and meters; to large-scale devices such as data recorders, totalizers, and system controllers.
Globalspec divides the Sensors, Transducers, and Detectors category into the following major families: acceleration and vibration, acoustic and audio, analytical, density and specific gravity, displacement, electrical and electromagnetic, encoders and resolvers, environmental, flow, force, gas, humidity and moisture, level, linear and orientation position, pressure, proximity or presence, rotary position, safety, temperature, tension, tilt, torque, velocity, viscosity, vision, and weather sensors. The lines between many of these categories are blurry as many of these sensors, detectors, and transducers are effective for testing within a number of similar areas.
