| |
Sensor Element / Chip
|
|
Denotes a "raw" device with no signal conditioning, or one with no packaging.
|
| |
Sensor / Transducer
|
|
A more complex device with packaging and/or signal conditioning that is powered and provides an output such as dc volts, 4-20mA, etc. (ex: a pressure sensor with 4-20mA output).
|
| |
Instrument / Meter
|
|
A (usually) self-contained unit that provides an output (typically a display) locally at or near the device. Usually also includes signal processing/conditioning. Example: a hand-held voltmeter.
|
| |
Gauge / Indicator
|
|
A device, which has a (usually analog) display and no electronic output. Example: a pressure gauge.
|
| |
Recorder / Totalizer
|
|
A device that records several data points or totalizes measurement in some fashion. It may also be capable of sophisticated functions such as statistical analysis.
