Technology & Mounting


	Gaging Technology
	Your choices are...
	Laser Micrometer		Laser micrometers and gages are instruments that measure extremely small distances using laser technology.
	LED / Optical Micrometer		Gages use light emitting diode (LED) based technology to measure dimensional features.
	Video Micrometer		Gages use imaging or video-based technology to measure dimensional features. A video micrometer projects two lines onto an object and provides a measurement of the distance between the two lines after calibration.
	Other		Other unlisted, specialized, or proprietary technology types.
	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.

	Non-contact?		Non-contact gages and gaging systems measure the dimensional features of a part without making contact with these features. Typically, non-contact instruments are used when a part's function or assembly does not allow for marring or damage to the part during measurement.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Type


	Mounting / Loading
	Your choices are...
	Automatic / Inline		Gages or systems where the part is automatically presented to the gage and measured without operator intervention. Inline designates that the automatic gages are applied in a production line. Usually, shadow type or CCD based laser micrometers are used in these applications. These laser micrometers can maintain high accuracy levels during production gaging of moving products such as wire, webs, or bar.
	Benchtop / Floor		Benchtop, table-based or floor mounted gage or instrument where a part is both manually loaded and measured. Laser scanning or rastoring type micrometers are commonly applied and provide sufficient accuracy in most stationary or benchtop applications.
	Handheld / Portable		Devices can be operated while being held in the hand and/or are portable.
	Machine Mounted		Gage mounted within, or on, a machine tool or process equipment for tool setup or travel measurement. Test indicators, dial indicators or micrometer heads are example of gages that are often machine-mounted.
	Other		Other unlisted, specialized or proprietary mounting or loading types.
	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.

	Configuration:
	Your choices are...
	Dual Head		The transmitter and receiver are independently positioned in two separate units or heads.
	Single Head		The transmitter and receiver are tied together on a single structure.
	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.

Specifications


	Range:		The total range length or dimensional range that gages can measure.
	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.

	Resolution:		The best or minimum graduations for scaled or dial-indicating instruments, or the best or minimum resolution for gages with digital displays.
	Search Logic:		All matching products will have a value less than or equal to the specified value.

	Speed:		Speed refers to either ultimate response speed for CCD type micrometers or to scan speed for laser rastoring type micrometers. Scan speed is the same as '1 / (response time)'
	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.

	T/R Separation:		T/R separation is the distance between the transmitter and receiver heads in the laser micrometer.
	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.

	Laser/Visibility Type:
	Your choices are...
	Visible Laser Light (680nm)		Lasers produce lightwaves that are visible to the naked eye (400nm - 680nm).
	Infrared Laser Light (>680nm)		Lasers produce lightwaves greater than 680nm.
	Laser Class I		Lasers are not hazardous for continuous viewing or are designed to prevent human access to laser radiation. These devices consist of low power lasers or higher power embedded lasers (i.e. laser printers).
	Laser Class II		Lasers emit visible light. Because of normal human aversion responses, these devices do not normally present a hazard; however, they would do so if viewed directly for extended periods of time (like many conventional light sources).
	Laser Class III		Lasers normally would not cause injury to the eye if viewed momentarily, but would present a hazard if viewed using collecting optics.
	Search Logic:		Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Measurement Scale & Output


	Units:
	Your choices are...
	English		Gages and gaging systems are based on the English system of measurement (e.g., inches).
	Metric		Gages and gaging systems are based on the metric system of measurement (e.g., centimeters, millimeters).
	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.

	Display Type
	Your choices are...
	Digital Display		Digital display types present metrology data in numeric or alphanumeric form. Micrometers, calipers, and indicators are available with digital displays. Gages with digital displays often have data output capabilities using serial or other formats. Digital readouts are a precision type of digital display integrated into dimensional gages or systems.
	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 Output:		The type of electrical signal that will be produced.
	Your choices are...
	Analog Current (4-20mA, etc.)		Transmitters are useful when sending signals over long distances. 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.
	Analog Voltage		The output voltage is a simple (usually linear) function of the measurement.
	Serial		Standard serial, digital output protocols include RS232.
	Parallel		Standard parallel, digital output protocol include the general-purpose interface bus (GPIB), a standard also known as IEEE 488.
	GPIB / IEEE 488 / HPIB		The output is transmitted via a standard digital protocol capable of carrying more than one bit simultaneously, such as GPIB, HPIB, IEEE 488, etc.
	Other		Other unlisted, specialized, or proprietary output types.
	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.

Measurement Capability


	Measurement Capability:
	Your choices are...
