Digital Bargraphs Specifications

Help with Digital Bargraphs specifications:

Display

	Display Technology
	Your choices are...
	LED		A panel meter where the segments are represented by light emitting diodes (LEDs).
	LCD		A panel meter where the segments are represented by dark areas in a liquid crystal display.
	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.
	Standard Display Colors		Bi-color LED's are made using red and green LED's in the same package. Most indoor programmable LED displays today use either all red LED's or they use red and green LED's. To a lesser extent all amber is sometime selected. It is possible to create 256 or more shades of color from red to green using only red and green bi-color LED's. Blue LED's are the most expensive and have the highest brightness. Adding blue LED's to the red and green can give you over 1.7 million shades of color.
	Your choices are...
	Amber		The characters are amber in color.  Amber is a deep yellow color.
	Aqua		The characters are aqua in color.
	Blue		The characters are blue in color.  Common wavelength of 450 nm.

	Multicolor		The panel meter is capable of displaying characters in multiple colors.
	Other		Other unlisted color.

Inputs

	Analog Input Channels:		Number of all analog input channels. This includes both general & specific types.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.
	Voltage Range		The range of voltages the meter is capable of measuring.
	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.
	Current Range		The range of currents the meter is capable of measuring.
	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.
	Frequency Range		The range of frequencies the meter is capable of measuring.
	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.
	Analog Input Type
	Your choices are...
	AC Voltage		Input is received as a measurable form of AC voltage.
	DC Voltage		Input is received as a measurable form of DC voltage.
	AC Current		The input is designed to receive AC current.
	DC Current		The input is designed to receive DC current.
	Frequency		The input is designed to receive a frequency or pulse.
	Single Phase AC Power		Input is received as an adjustable range of single phase AC current, voltage and/or frequency.
	Three Phase AC Power		Input is received as an adjustable range of three phase AC current, voltage and/or frequency.
	DC Power		Input is received as an adjustable range of DC current, voltage and/or frequency.
	Strain Gauge		A strain gauge is a sensing device, attached along its entire length to a surface so that its resistance will change as the surface is deformed. Strain gages are typically used as elements in a Wheatstone bridge circuit, which is used to make the measurement.
	Resistance		Piezoresistive sensors are based on semiconductor technology. The resistance changes because of alterations in the length and width (as with strain gauges) as well as a shift of electrical charges within the resistor.
	Temperature		Thermocouple (TC), RTD or thermistor input accepted.
	Other		Other unlisted type of input.
	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.

Outputs

	Output Type
	Your choices are...
	Analog		Analog outputs are used in applications that require digitally controlled output voltages usually within the range of +/-10 V or less, and at current levels below 10 mA. The heart of an analog output channel is a digital-to-analog converter (DAC), which converts a digital code into a voltage level. The output of the DAC is then processed or conditioned to produce the required output signal characteristics.
	Parallel		A channel capable of transferring more than one bit at a simultaneously.
	Serial		A port, or interface, that can be used for serial communication, in which only one bit is transferred at a time.
	Relay		One of the most common types of outputs available is the relay output. A relay can be used with both AC and DC loads.
	Other		Other unlisted type of 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.

	Adjustable Display		The meter can be adjusted to show different displays.
	Alarms		The meter has alarms to indicate when limits or set points are reached.
	Displays Digits		The meter also has a digital display.
	Intrinsically Safe		At facilities where there are flammable or explosive materials, operating at low energy can prevent electrical devices from creating arcs, sparks, or heat (during normal or fault conditions) that could ignite the explosive substance. Such a system is termed "intrinsically safe."
