Linear Measurement Range:
|
|
Distance range over which the sensor or instrument operates in the linear range, or within its design accuracy.

Search Logic:
|
|
User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
|
|
| |
Sensing Frequency Range:
|
|
The frequency range over which the device operates. Enter "0" to indicated DC response, if desired.

All matching products will have a value greater than or equal to the specified value.
|
|
| |
Static Resolution:
|
|
Resolution is the smallest increment of the quantity that can be recognized. It tells you how much change in a quantity is required for the sensor to detect the change. For very small changes in position you would want a sensor with a very tight (small) resolution. There are two types of resolution, Static and Dynamic. Dynamic Resolution = Static Resolution x (Bandwidth)^1/2

All matching products will have a value less than or equal to the specified value.

|
| |
Nonlinearity:
|
|
Deviation from a purely linear response in the measuring region; lower linearity deviation values denote more accurate reading throughout the measuring range.

Electrical Output
|
|
The type of electrical signal that will be produced. This category includes analog and digital signals for communicating directly to a computer, and switched or discrete-level output.
|

Your choices are...
|
|
|
| |
Analog Current
|
|
Often called a transmitter. A current is imposed on the output circuit proportional to the measurement. Feedback is used to provide the appropriate current regardless of line noise, impedance, etc. Useful when sending signals long distances. Common examples of analog current or transmitter ranges are 4-20 mA, 0-20 mA, and 0-50 mA.
|
| |
Analog Voltage
|
|
Output voltage is a simple (usually linear) function of the measurement. Examples include 0-10V, ±10V, etc.
|
| |
Serial Interface
|
|
A standard digital output protocol (serial) such as RS232, RS422, RS485, etc.
|
| |
Parallel Interface
|
|
Output conforms to a digital parallel protocol such as GPIB / IEEE-488 / HPIB. Common examples of parallel interfaces include printer ports and Centronics®.
|
| |
Other
|
|
Unlisted or specialized output configuration.

Shielded?
|
|
A shielded sensor can be embedded in metal (made flush). A non-shielded sensor is usually side-sensitive.

Intrinsically Safe?
|
|
Intrinsically safe (IS) is an adjective for equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture in its most ignited concentration. The IS terminations and wiring may be brought into any hazardous location of any group classification for which it is accepted without requiring explosion proof housing or other means of protection.

| |
Nonmagnetic Targets
|
|
Detection targets do not require magnetization.
|
| |
Ferrous Targets
|
|
Targets for position detection include iron or iron-based materials such as steel, stainless steel, etc.
|
| |

Device Type
|
|
For the purposes of this question, device types are separated into general categories based on what they are designed to do or what you have to do to use them. The 'category' criteria attempts to distinguish 'unpacked' sensors that might be used as part of a larger sensor from, say, a gauge which can be read just by looking at it.
|
| |
Your choices are...
|
|
|
| |
Sensor Element / Chip
|
|
Denotes a "raw" device such as a thermocouple, 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.
|
| |
Gauge / Indicator
|
|
A device that has a display (needle, digital readout, etc.) and no auxiliary electronic output.
|
| |
Instrument / Meter
|
|
Typically, a self-contained unit that provides an output (usually a display) locally at or near the device. May also include signal processing and conditioning. Example: a hand-held voltmeter.
|
| |
Recorder / Totalizer
|
|
A device that records several data points or is used to totalize measurements in some fashion. It may also be capable of sophisticated functions such as statistical analysis.
|
| |
Controller
|
|
Controllers are devices that accept sensor input and provide control function (limits, PID, logic, etc.) via one or more control signal outputs.
