Noncontact Infrared Temperature Sensors Specifications

Help with Noncontact Infrared Temperature Sensors specifications:

Performance Specifications

	Temperature Range		The range of temperature that you need to measure.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
	Accuracy		The accuracy of the measured temperature as a percentage of the reading.
	Search Logic:		All matching products will have a value less than or equal to the specified value.
	Spectral Range		Near IR = 0.75-3µm, Middle IR = 3-6µm, Far IR = 6-15µm, Extreme IR = 15-30µm.
	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.
	Response Time		The response time is the time it takes for the instrument to measure temperature.
	Search Logic:		All matching products will have a value less than or equal to the specified value.
	Operating Temperature		The temperature range over which the device must operate.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
	Responsivity		Responsivity measures the input–to-output gain - the increase in electrical output per optical input signal of a photodetector system.
	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.
	Detectivity		Detectivity is a performance measure of a photodetector, equal to the reciprocal of the noise equivalent power (NEP), and normalized to unit area and unit bandwidth. Units are centimeters * Hertz ^(1/2) / Watt, also written shorthand as the "Jones" unit, in honor of the scientist who defined this magnitude.
	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.

Device Category

	Device Category		You can think of products as belonging to general categories based on what they are designed to do and 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...
	Element / Chip		A sensor element or chip denotes a "raw" device such as a thermocouple, or one with no packaging.
	Sensor / Transducer		A sensor is a device that converts a measured temperature into an electrical output signal.  Typically, a temperature sensor will be a simple device with no display or user interface.  A temperature transducer is a temperature sensing device with packaging, signal conditioning, and compensation.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Technology

	Technology
	Your choices are...
	Optical Pyrometer		Optical pyrometers include: photon / quantum effect detectors and 2-color devices.
	Thermal Pyrometer / Detector		Infrared temperature sensors based on thermal technology may include: bolometers (variable resistance / thermistor), thermocouples / thermopiles, or pyrometers / pyroelectric detectors.
	Other		Other unlisted, specialized, or proprietary technology.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Electrical Outputs and Features

	Electrical Outputs
	Your choices are...
	Current		Often called a transmitter. A current (4-20mA, or any other analog current output) is imposed on the output circuit proportional to the measurement. Feedback is used to provide the appropriate current regardless of line noise, impedance, etc. This output is useful when sending signals long distances.
	Voltage		The output voltage is a simple (usually linear) function of the measurement.
	Switch / Alarm		The output is a change in state of a switch or alarm.
	Serial		The output of the transmitter sends out a serial communications signal, such as, RS-232 or RS-485.
	Other		Other unlisted, specialized, or proprietary output.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Automatic Emissivity Adjustment		The emissivity adjustment allows the device to detect only the emitted IR as opposed to the reflected or transmitted IR which would give a false temperature reading.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Laser Spot Aiming / Sighting		The device has a laser to show where measurement is being taken from. Laser is not used to sense temperature.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Battery Powered		The device is powered by a battery or battery pack.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
